Precision measurement of the $B^0$ meson lifetime using $B^0\to J/\ddot{I}ˆK^{\ast 0}$ decays with the ATLAS detector

ATLAS Collaboration

A measurement of the $B^0$ meson lifetime using $B^0\to J/\ddot{I}ˆK^{\ast 0}$ decays in data from 13 TeV proton-proton collisions with an integrated luminosity of 140 fb${}^{-1}$ recorded by…
