Large Hadron Collider achieves 2011 data milestone

Today at around 10:50 CEST, the amount of data accumulated by Large Hadron Collider experiments ATLAS and CMS clicked over from 0.999 to 1 inverse femtobarn, signalling an important milestone in the experiments' quest for new physics. The number signifies a quantity physicists call integrated luminosity, which is a measure of the total number of collisions produced. One inverse femtobarn equates to around 70 million million (70 x 1012) collisions, and in 2010 it was the target set for the 2011 run. That it has been achieved just three months after the first beams of 2011 is testimony to how well the LHC is running.

"It's great to have delivered this amount of data in time for the main summer conferences," said ’s Director for Accelerators and Technology, Steve Myers. “When we set ourselves the objective of achieving one inverse femtobarn in 2011, it was for good reason: that amount of data could well give us access to exciting new physics.”

The experiments are now working hard to get results ready for the main summer physics conferences: the European Physical Society’s High Energy Physics conference, which will be held in Grenoble from 21 to 27 July, and the Lepton-Photon conference, this year hosted by the Tata Institute in Mumbai from 22 to 27 August.

Among the new physics the LHC experiments are searching for are the Higgs mechanism and supersymmetry. The Higgs mechanism, and its associated particle, is the last missing ingredient of the so-called Standard Model of particle physics that explains the behaviour and interactions of the fundamental particles that make up the ordinary matter from which we and everything around us are made. The Higgs mechanism gives rise to the masses of certain particles.

Ordinary matter, however, appears to be only around 4% of what the Universe is made of. Supersymmetry is a theory that goes beyond the Standard Model. It is a more elegant theory of ordinary matter, and could also explain the mysterious dark matter that makes up about a quarter of the universe. With one inverse femtobarn there’s a real chance that, if these theories are correct, they will start to manifest themselves in the data.

“This is a superb achievement, which demonstrates the outstanding performance of the accelerator and of the operation team,” said Fabiola Gianotti, spokesperson for the ATLAS experiment. “It's really great to have such a large amount of data in time for the main summer conferences. The ATLAS , in particular students and post-docs, are working hard and with great enthusiasm to produce exciting results, from precise measurements of the known particles to searches for the Higgs boson and other new phenomena. It's really a gorgeous moment!"

"With the LHC running at much higher intensity than initially foreseen, signals of new physics might appear any moment in our data," said CMS spokesperson Guido Tonelli. "Hundreds of young researchers all over the world are actively searching for new particles such as the Higgs boson, supersymmetric particles or new exotic states of matter. If nature is kind to us, we could have major breakthroughs even before the end of this incredibly exciting year"

A third LHC experiment, LHCb, requires less data than and CMS, but has also exceeded its expectations for the year.

“LHCb is currently taking data at a rate almost double that previously expected, thanks to the fantastic performances of LHC machine," said Pierluigi Campana, LHCb spokesperson. “We are chasing the rarest events and the new possible asymmetries of nature that could show up in the decays of beauty quarks. The amount of data we are collecting will put LHCb in the position to unveil the flavour of new physics. This an exciting time for everybody, in particular for our youngest colleagues, who have a leading role in this scientific adventure."

Although recording data with proton beams, the fourth major LHC experiment, ALICE, is specifically designed for physics with lead-ion beams, which will come during the last four weeks of the LHC’s 2011 run.

Congratulations to them! Now do Europeans say beauty quarks and Americans say bottom quarks, what's the deal there?

It will be interesting to see if they can cut off some Energy ranges for supersymmetric particles in the next coming years or make a revolutionary discovery. I am not sure what SUSY predicts. Any one know some basic parameters? It is amazing that the theory has survived for 40 years with no experimental confirmation.

Reality, when understood, is replicable. Theories will dissipate when reality is proven, only god theory shall remain. To move past quantization we need to move to the heart of matter, whether; conventional, anti-, or dark- matter, it all shares commonality - mass. Materialization via light is gods power. electromagnetic energy converts a neutral field point of no mass and no energy into a massive energetic point - matter. Energy (em) materializes reality. Energy interacts with space (spacial field) creating massive particles. There is nothing stopping regenesis. Conversion of matter into light (dematerialization) and re-materialization as long as the bits of information are not lost or changed. Reality is controllable. The Higgs boson does not exist independently (for long that is). The Higgs boson is the result of energy interacting with the higgs field. When you push something you exude a force on it, it exudes a negative force on you. Energy forces materialization in gods field.

But when you push hard enough it will break. The Higgs field has a breaking point. Tunneling out and in of reality bypasses it. Since reality is controllable higher planes exist. Cutting out of reality (through the singularity) delivers one to a higher dimension (higher plane). Infinite energy (equaling high universal limit) rips the Higgs field creating a singular point in space-time, not belonging to our spacetime (4D). Crossing the singularity brings one into a new dimension. The singularity of a blackhole is limited to itself. Is reverse crossability possible? Can one fall into a blackhole (out of our universal 4D space-time) and come back into it?

To create a singularity one requires perfectly aligned energy (focused on a singular spacial point). Infinite energy means a rational translation greater than or equal to Total Mass of Universe per its size after its emergence. If energy concentration is greater than that of the Big Bang we have a singularity. A rip in the fabric of spa

The more physicists know about the universe the harder they search for more detail. Hmmmm. Watch out people these physicists will pop in and out of existence in your path pretty soon. They will be able to live on pure energy alone : they will maintain their biological processes with only energy intake and thus their digestive tube will become obsolete.

That's why they have computers. And data warehouses.

Even a modern Formula-1 car generates data so fast during a race, that it takes weeks to analyze it, by the best engineers and massive computers.

Computers at the LHC sift, refine and store only the relevant parts from the massive data flow. Then other supercomputers again sift, refine and store that data, sorting out only the relevant information in that mass of data.

Only then do scientists start looking at what's left. And even that is an enormous amount of data. But you get the idea.

Protons have negative and positive charges comprising them. They have a positive net charge. There are three Higgs bosons in a proton.

Negative charges (electrons) and positive charges (positrons) when interact they destroy one another, merging of oppositely charged particles = light wave (alternating charge wave). Dark mass is matter with only positive, or only negative charges. Dark matter does not have light wave (photon) formation. No merging of negative and positive charges means no decay (weakforce) and no photons (em radiation). Matter of only one type of charge has mass (gravitational force) and it is either: 1. negative of charge or 2. positive of charge.

Decay is the result of negative positive mergance of energy. Photons and small particles emerge from matter because matter has negative and positive components the gravitational force produces pressure which determines density, this is strong force.

t radiate light (photons) and doesn't decay (as result of WEAKness of FORCE). Dark matter has only one directional spin (same charge). Negative and positive charge is required for decay. Light is wave formation from the two oppositely turning charges (loss of energy from particle). And breaking up of atoms is result of pressure loss, pressure is compression, gravity compresses. Gravitational pressure sets elemental limits (atomic composition). For atomic nuclei to be stable it can't be made up of just one charge, this would cause repulsion of the nuclei. This is where neutrons come in. Neutrons stabilize atomic nuclei by adding even charge therefore diluting the positive net charge, keeping it positive but reducing the positive repulsion, this enables negative charged electrons to hold the nuclei together. When the nuclei is too heavy (too diluted by neutrons) and it is extracted from the material holding it together, it begins to lose charges.

(gamma (neutral charge wave), positive charges (positrons), and negative charges (electrons))

Neutrons also emerge and they cause matter to get heavier without charge change.

Alpha gamma and beta radiation.

Dark matter does not form materials. Same charges repel and therefore keep a uniform distance from each other. Dark matter affects us 1. gravitationally, and 2. the repulsive energy of common charge.

Dark matter 1. adds mass and 2. Pushes space apart with the electric field it generates with spin. Repulsion and mass.

So exotic is out. Dark mass does not clump up like galaxies do because of their negative and positive charge attraction, dark matter is different the gravitational attraction doesn't cause materialization unless we have sufficient pressure (gravitational or external compression) also by diluting charge consistency we lower the pressure requirements for matter (what we call atomic elements) to form.

Huge gravitational pressure is required for an UP quarks star to form. The positive charges repel each other, huge pressure is required to hold positive charges together. The UP quark star quickly begins to degenerate, the positively spinning charges begin to impact the charges beside them inverse their spin causing them to change their spin and charge. The UP quark star would quickly explode, BANG. If that didn't happen though, what would happen is reversal of 50% of UP quarks, leaving an equal amount of negative and positive charges, neutral net charge, a neutron star. If an UP quark star

formed it would quickly decay into a neutron star, as long as the gravitational force was greater than local charge repulsion. If repulsive force is greater no neutron star has time to form, the star explodes.

This illustrates the repulsive strength of common charge. This is dark energy.

- we cannot see electrons, we can only see the points in space where the negative energy of the electron interacts with positive energy. Photons are made when charges annihilate. No differing charges no photons. -

Regardless of the verdict I am almost certainly correct (as correct as one can be with this uncertain physical world). I've formulated and deduced the most likely scenario but unless I succeed in replication - which I havent yet - all I'm left with is theory. The world around us is weird, it is nearly impossible to define something you yourself are a product of. Until one creates their own universe he does not understand it. We can understand the interactions by calculating the mechanics but we cannot prove anything but mechanics theoretically. Many theories fit reality but reality is just one. The unifying theory rids all others by giving us reality. To prove reality you must recreate it in your image. Imagine...

Authentic wacko most likely, but a wacko that dreams of furthering humanity by answering the most fundamental of questions: - What are we? Where did we come from? How did we get here? - and with all those answered we'll hold the power to direct where we are going.
