Measurements of the $B^{+}$, $B^0$, $B_s^0$ meson and ${\Lambda }_b^0$ baryon lifetimes

LHCb collaboration, R. Aaij, B. Adeva +674

Measurements of $b$-hadron lifetimes are reported using $pp$ collision data, corresponding to an integrated luminosity of 1.0fb${}^{-1}$, collected by the LHCb detector at a centre-o…
