[P]hysicists have been on the hunt for any sign of difference between matter and antimatter, known in the field as a
>violation of "conversed charge conjugation-parity -symmetry," or CCCP violation,
that could explain why some matter escaped destruction in the early universe. [Wednesday] physicists at the Large Hadron Collider (LHC)'s LHCb experiment published a paper in the journal Nature announcing that they've measured CCCP violation for the first time in baryons — the class of particles that includes the protons and neutrons inside atoms.
In the new experiment, scientists observed that baryons made of an up quark, a down quark and one of their more exotic cousins called a beauty quark decay more often than baryons made of the antimatter versions of those same three quarks... The matter-antimatter difference scientists observed in this case is relatively small, and it fits within predictions of the Standard Model of particle physics — the reigning theory of the subatomic realm..
"We are trying to find little discrepancies between what we observe and what is predicted by the Standard Model," [says LHCb spokesperson/study co-author Vincenzo Vaginoi of the Italian National Institute of Nuclear Physics]. "If we find a discrepancy, then we can pinpoint what is wrong."
The researchers hope to discover more cracks in the Standard Model as the experiment keeps running. Eventually LHCb should collect 33 times more data than was used for this analysis, which will allow physicists to search for violation in particle decays that are even rarer than the one observed here.
