Particle oddball surprises physicists

Mar 18, 2009
The Tevatron typically produces about 10 million proton-antiproton collisions per second, sometimes creating particles known as B mesons. A B meson contains a quark-antiquark pair that includes either a bottom quark or anti-bottom quark. B mesons can decay directly into a J/Ψ (psi) particle and a Φ (phi) particle. The CDF scientists found evidence that some B mesons unexpectedly decay into an intermediate quark structure identified as a Y particle.

(PhysOrg.com) -- Scientists of the CDF experiment at the Department of Energy's Fermi National Accelerator Laboratory announced yesterday that they have found evidence of an unexpected particle whose curious characteristics may reveal new ways that quarks can combine to form matter. The CDF physicists have called the particle Y(4140), reflecting its measured mass of 4140 Mega-electron volts. Physicists did not predict its existence because Y(4140) appears to flout nature's known rules for fitting quarks and antiquarks together.

"It must be trying to tell us something," said CDF cospokesperson Jacobo Konigsberg of the University of Florida. "So far, we're not sure what that is, but rest assured we'll keep on listening."

Matter as we know it comprises building blocks called . Quarks fit together in various well-established ways to build other particles: mesons, made of a quark-antiquark pair, and , made of three quarks. So far, it's not clear exactly what Y(4140) is made of.

The CDF collaboration found evidence for a new particle dubbed Y(4140), produced by the Tevatron collider at Fermilab. The particle's signature peak became apparent when scientists analyzed the decay of particles that produce pairs of muons and pairs of K mesons, revealing a new particle structure. The Y particle has a mass of 4140 Mega-electron volts.

The Y(4140) particle decays into a pair of other particles, the J/psi and the phi, suggesting to physicists that it might be a composition of charm and anticharm quarks. However, the characteristics of this decay do not fit the conventional expectations for such a make-up. Other possible interpretations beyond a simple quark-antiquark structure are hybrid particles that also contain gluons, or even four-quark combinations.

The CDF scientists observed Y(4140) particles in the decay of a much more commonly produced particle containing a , the B+ . Sifting through trillions of proton-antiproton collisions from Fermilab's , CDF scientists identified a small sampling of B+ mesons that decayed in an unexpected pattern. Further analysis showed that the B+ mesons were decaying into Y(4140).

The Y(4140) particle is the newest member of a family of particles of similar unusual characteristics observed in the last several years by experimenters at Fermilab's Tevatron as well as at KEK laboratory in Japan and at DOE's SLAC National Accelerator Laboratory in California.

"We congratulate CDF on the first evidence for a new unexpected Y state that decays to J/psi and phi," said Japanese physicist Masanori Yamauchi, a cospokesperson of KEK's Belle experiment. "This state may be related to the Y(3940) state discovered by Belle and might be another example of an exotic hadron containing charm quarks. We will try to confirm this state in our own Belle data."

Theoretical physicists are trying to decode the true nature of these exotic combinations of quarks that fall outside our current understanding of mesons and baryons. Meanwhile experimentalists happily continue to search for more such particles.

"We're building upon our knowledge piece by piece," said CDF cospokesperson Rob Roser of Fermilab, "and with enough pieces, we'll understand how this puzzle fits together."

The Y(4140) observation is the subject of an article submitted by CDF to Physical Review Letters this week. Besides announcing Y(4140), the collaboration is presenting more than 40 new results at the Moriond Conference on Quantum Chromodynamics in Europe this week, including the discovery of electroweak top-quark production and a new limit on the Higgs boson, in concert with experimenters from Fermilab's DZero collaboration. Both experiments are actively pursuing a very broad program of physics, including ever-more-precise measurements of the top and bottom quarks, W and Z bosons and searches for additional new particles and forces.

"Thanks to the remarkable performance of the Tevatron, we expect to greatly increase our data sample in the next couple of years, said Konigsberg. "We'll study better what we've found and hopefully make more discoveries. It's a very exciting time here at Fermilab."

It's not a particle, you people.

It is merely an externally stabilized vortex, via it's origin field pressures and that of adjacent 2-d fields.

They are literally 2-d field interactives passing in-out of this dimension, leaving a 'trace' that becomes this 3-d time based dimension we call reality. We are dimensional foam on the back of infinitely big interactive 2-d fields. Those 2-d fields, which are AMPLITUDE based, whereas our 'foam', that we call 'reality'..is frequency and oscillation based, with regards to the interactive between these 'opposing flow relations'.

This is why we always have particle and anti-particle as pairs.

Energy cascades through the system into ours via the mechanism of slight offsets in the resonance pattern that is enforced and held by these field interactives.

They are merely 2-d field interactive resonant vortexes. Resonance and frequency constitutes manipulation. is this not clear? This is what all our 'masters of matter and energy' have done over the years.

We,as 3-d structures (in 'time'), are merely a vantage point, as a barely stabilized vector of these energies. That is our vantage or viewing point.

When you see a cascading water system..and you see a point where the water drops a bit..and there..on the stabilized 'foam' point in the lower front edge of it..you see a 'rubber duckie' floating along..not moving downstream..and not being engulfed by the cascade.. just bobbing along in it's little area...that rubber duckie is -US- in our little '3-d space/time thingie'

Why do you think that enriched complex vortexes like uranium are so easy to break apart? The resonant field of their interactive is very messy..and thus..it can be shattered and the fields spring apart, like giant Gordian knots made of infinite 2-d fields. Think about it.

Gravity, time, magnetism, etc..are all residual interactives of these structures (atomic/vortex) which have a numerical resonance complimentary number/freq that is an offshoot of the main 2-d field frequencies..which are near infinite.

That's all there is to it. End of story.

Get with the program.

The particle is obviously screaming: "Heeeelp! Free me from the chains of the Standard Model! I am just a simple looping EM wave..."
