New ATLAS measurement of the lifetime of the electrically neutral beauty meson is the most precise to date

The collaboration has found evidence of CP violation in decays of baryons and in decays of beauty hadrons into charmonium particles

The finding also represents the first evidence of the heaviest antimatter hypernucleus yet at the LHC
