In order not to create excessive expectations, the scientists of the LHCb experiment (acronym for Large Hadron Collider beauty experiment, where beauty refers to the beauty quarks) warn that much work remains to be done to collect evidence to support and justify the “invention” of a new physics.
Beauty quarks, which are reputedly unstable, decay into other particles in a fraction of a minute, and “turn” into muons and electrons, producing both in equal amounts.
And, roughly speaking, particles never seen before acting on the decay of quarks can signify the existence of a new fundamental force of nature.
This conclusion is because the decay of beauty quarks is mediated by one of the three fundamental forces described by the Standard Model, the weak force.
The March study looked at beauty quarks paired with “up” quarks, while the new research looked at two decays: one from beauty quarks paired with “down” quarks and one paired with “up” quarks as well.
The idea is that the decay should be the same if there really is a new force affecting the beauty quarks.
The result of new research on beauty quark decay is available on arXiv and awaits peer review
