Particle Physics

Physicists on the LHCb experiment at CERN's Large Hadron Collider have detected the Xicc+ particle, a baryon containing two charm quarks and one down quark. This heavier analogue of the proton resolves a 20-year-old mystery from a previous experiment. The discovery, confirmed at over 7 sigma significance, highlights upgrades to the LHCb detector.

An international team has initiated the MACE experiment to detect a rare transformation of muonium into its antimatter counterpart, antimuonium. This process, if observed, would challenge the Standard Model of particle physics by violating lepton flavor conservation. The project aims to vastly improve upon previous searches conducted over two decades ago.
