The LHCb collaboration at CERN has observed the ultra-rare decay of the Sigma-plus baryon into a proton and two muons, a process that could reveal physics beyond the Standard Model and help understand matter-antimatter asymmetry. This achievement was made possible by analyzing extensive data from proton-proton collisions and employing machine learning techniques, marking a significant milestone in particle physics research.
A new discovery at Cern's LHCb experiment reveals differences in the decay rates of matter baryons and their antimatter counterparts, providing insights into why the universe is dominated by matter and not antimatter, and hinting at potential new physics beyond the standard model.
The LHCb collaboration at CERN has made significant progress in understanding the χc1(3872) particle, a puzzling entity in particle physics. Using data from LHC Run 1 and Run 2, they found that the particle's decay ratios are inconsistent with a pure molecular hypothesis, suggesting it contains a compact component. This supports theories that χc1(3872) could be a conventional charmonium, a compact tetraquark, or a mixture of molecules with a compact core.
