Research team predicts the next big thing in the world of particle physics: supersymmetry

Jan 11, 2012 By Jana Smith

(PhysOrg.com) -- A better understanding of the universe will be the outgrowth of the discovery of the Higgs boson, according to a team of University of Oklahoma researchers.   The team predicts the discovery will lead to supersymmetry or SUSY — an extension of the standard model of particle physics.  SUSY predicts new matter states or super partners for each matter particle already accounted for in the standard model.  SUSY theory provides an important new step to a better understanding of the universe we live in.

Howard Baer, Homer L. Dodge Professor of High Energy Physics in the OU Department of Physics and Astronomy, and his colleagues were the first in the world to show what SUSY might look like at colliding beam experiments.  Baer has published books and papers on SUSY; most recently, a paper on implications of recent evidence of the Higgs boson at the Cern Large Hadron Collider for SUSY theory.

Baer has studied SUSY for 25 years and believes the of the Higgs boson will open the door to a whole new world of super particles.  The Higgs boson is the standard-model particle that gives all other particles mass.  According to Baer, “Finding the Higgs is like looking for a needle in a haystack, but the is only the tip of the iceberg of SUSY matter.”

“With SUSY,” says Baer, “we are talking about the next level of the laws of .  If there is SUSY, then we will find super partners, which will provide a new perspective for the origin and evolution of the .  At that point, we can say we are on the road to a much deeper comprehension of nature.”

SUSY may be the next big step in understanding cosmology and the origin of dark matter, the so-called invisible particles that dominate the matter density of the universe.  OU has several theorists and experimentalists working to validate SUSY theory.  Baer has developed computer code over a 25-year period that calculates super particle masses and production rates for the LHC located at Cern in Switzerland.

The LHC is already looking for SUSY, but has had no success so far. Atlas and CMS experiments will provide new analysis on SUSY in March 2012. In the next three years, the LHC will double the energy required to prove the SUSY theory—another important step in understanding the universe as we know it today.

This is wishful-hype by Howie. LHC closed out the parameter space up to ~800Gev, & SUSY theorists predict that if its not seen at around a Tev, SUSY is Toast ! String theory sans SUSY suffocates to death as well. In addition, no black holes have been seen at LHC, so A new breath of fresh air must enter physics soon.

IMO notoriously known neutrino is superpartner of photon, these SUSY theorists just don't understand their own theory. It doesn't imply the existence of WIMPs and another superpartners, though. SUSY is actually thirty years old theory and the latest result from LHC already disproved it.

IMO physicists are just seeking the pretense for another continuation of LHC experiments, or they would lost their jobs.

Mass and gravity could also be generated by the energy density of quantum vacuum. This model does not require existence of Higgs boson and graviton.

It's essentially the dense aether model of AWT. In this model the massive particles are condensing like the droplets from particle gas or like the solitons at the water surface. But this model has another consequences. For example, in this model the space-time can be never completely flat, it should contain some density fluctuations, which can be interpreted as a Higgs bosons. The difference is, this model doesn't require the Higgs boson of discrete or even fixed mass - it's mass could be completely continuous, which violates the concept of quantization of mass and energy at Planck scale. My opinion is, both these models can be correct. It's easier to demonstrate it at the cosmological scale, where the spacetime forms a sparse fractal mesh of foamy density fluctuations of dark matter.

From AWT follows, the same fractal structure which we are observing in structure of dark matter should emerge at the quantum scale. This structure is not completely fuzzy, it exhibits spectral peaks which correspond the nested dodecahedral symmetry (dodecahedrons are Platonic solid, which generate most regular structure of foam). The same geometry is responsible for so called Penrose circles, which were observed inside of dark matter.

From this model follows, the space-time is not completely uniform at the Planck scale, it has foamy structure, which prefers some masses of Higgs boson over another ones - but it's not composed of distinct quantized particles anyway too. The problem is actually following - at the atom nuclei scale the Universe is well quantized and symmetric in the same way, like at the scale of objects composed of mostly atom nuclei (neutron stars). But the more we are distant from these two scales, the more the Universe appear symmetric and fuzzy.

Let say, we are standing inside of fractal landscape, which has its distribution well defined. But because from certain distance everything is covered with omnipresent fog, we will not see any regularity at the infinite distance anyway. The regularity of Higgs field is therefore a compromise between schematic regularity of formal theories and the observability of Universe at the sufficiently small or large scale. If we would travel around fractal landscape covered with fog, then many details and regularities would reveal itself at proximity. So I'm convinced, if we could shrink to the distance and energy density scale of atom nuclei, we would see our neighbourhood as regular, as we can see the Universe around us and the regularity of Higgs field would shift toward smaller scale accordingly. The same rich and complex world could exist inside of black holes or outside of event horizon of Universe - we just cannot see it because of dispersion of light with omnipresent vacuum fluctuations.

There is well known fact, the quantum mechanics implies so-called hierarchy problem. For example, in explanation of Brownian motion the smaller time interval we take, the faster average speed of particles we get and with decreasing scale the energy density increases ad infinitum. From this reason Standard Model doesn't predict any particular mass of Higgs boson: every possible values are allowed in it. Which is essentially correct, because the same mechanism is responsible both for Yukawa force at quantum scale, Casimir force at microscopic scale and/or dark matter effects at large scales. In all cases we are facing some tiny fluctuations of vacuum, which are shielding the massive objects and which result into cohesive forces at short distance scales.

Formally thinking physicists aren't indeed satisfied with this situation, so they're proposing various constrains, which would limit the scale of Higgs boson field and which would lead into calculable values of Higgs boson mass.

So far the most elaborated attempt is the supersymmetry, which is based on the following analogy. When ideal wave spreads along water surface, it doesn't affect the water density inside it. But we can consider the water as a compressible fluid, so that every surface wave induces the pressure wave in the underwater, which may resonate mutually. This resonance substantially constrains the spectrum of waves of both types present in the system. Furthemore, from this model follows, when surface wave forms a particle (wave packet or soliton), then every surface soliton should have its dual analogy/counterpart in soliton of underwater waves and vice-versa. Such dual pairs of solitons exists at the water surface: Russell's and Falaco solitons. This idea is therefore physically relevant and it quite old, for example in 1966 was proposed already, the meson solitons floating at the surface of atom nuclei could act as as supersymmetric counterparts of hadrons inside of them.

In context of GUT the three generations of gauge bosons are called photons, gluons and W/Z-bosons correspond the three generations of photions, i.e. the neutrino, muino and tauino. Photons undergo the quantum oscillations in the same way, like the neutrinos - in this case it's called a decoherence, but it's essentially the very same process: the photons undergo repetitive changes into particle-antiparticle pairs and back again inside of field of quantum fluctuations. Photons mostly occur without spin, but they may exhibit polarization (spin) - in this regard they're dual to neutrinos, which are mostly charged particles, but they may occur in form of sterile neutrinos. The lower energy/higher energy the photons/neutrino has, the more easier it forms neutral form, which manifests with superluminal speed for photons/neutrinos of lower/higher energy than the energy of CMBR photons.

All people that started before that data have starting dates right around that. Any inference based on starting dates from that day or the next are built on sand.

Mabarker used to have posts from 2005 IIRC.

Well it is good to see that they are at least getting closer. It's clear the higgs boson is theoretical, and very similar to the 'ether' of centuries before (meaning it does not exist). But, when I say they are getting closer, that simply means their efforts at consciously realizing something by consciously observing it is improving. Not quite there yet, but that is the their main idea and the thought process in use. . .And, will eventually be the key to the entire understanding of everything. Call it super symmetry, or whatever you want, that's what will come out of it, and lead to the first real 'time travellers'. I should not be disclosing this sort of information, however, here, I believe it's probably so far-fetched as to be easily dismissed, so should be safe in sharing here. Perhaps what I say here will have some effect, and, that is honestly part of our experimental projects. Guten Tag
