Study of the $\Xi_b^-$ baryon decay at CMS
A preliminary measurement of the $\Xi_b^-$ baryon lifetime through the decay chain $\Xi_b^-$ → J/ψ$\Xi^-$ −, where J/ψ → µ$^{+}$µ$^{−}$, $\Xi^-$ → Λ$^{0}$π$^{−}$ and Λ$^{0}$ → pπ$^{−}$, using 5.1 fb$^{−1}$ of integrated luminosity of data from proton-proton collisions with a center-of-mass energy of...
