Accelerators and storage rings are coupled physical systems designed to generate, manipulate, and store high-energy charged particle beams under precisely controlled electromagnetic fields. Accelerators, such as linear accelerators or synchrotrons, use radiofrequency cavities and magnet lattices (dipoles, quadrupoles, higher multipoles) to incrementally increase beam energy and control transverse and longitudinal dynamics. Storage rings maintain beams on closed orbits for extended durations, employing sophisticated lattice designs, beam optics, and feedback systems to preserve emittance, energy spread, and stability while enabling collisions or extraction for experiments, synchrotron radiation production, or secondary beam generation.
The ATLAS collaboration at the Large Hadron Collider (LHC) has released a new high-precision measurement of the lifetime of the electrically neutral beauty (B0) meson—a hadron composed of a bottom antiquark and a down quark.
