New Particle Identified At LHC

First time accepted submitter m4ktub writes "A team of researchers working with the ATLAS experiment at the LHC have published an article in arXiv where they describe what is believed to be the first observation of a new particle: the boson Chi-b (3P). Professor Roger Jones, Head of the Lancaster ATLAS group, said 'While people are rightly interested in the Higgs boson, which we believe gives particles their mass and may have started to reveal itself, a lot of the mass of everyday objects comes from the strong interaction we are investigating using the Chi-b.'"

Re:Quark and anti-quark?

[PvtVoid]

Within quark theory, quark/antiquark annihilation is not defined, as that has not been necessary to explain the phenomena we have observed nor does it lead to any verifiable predictions.

This is total nonsense. Quark/antiquark annihilation is perfectly well-described in standard theory. The answer to the OP's question is that the quark and antiquark do annihilate, which is why all mesons are unstable. But it takes a little bit of time for the annihilation to happen, which gives you the lifetime of the meson.
