Measurement of Bc Mass and Lifetime at LHCb

Abstract

The $B_c^{\pm }$ mass and lifetime measurements using the decay $B_c^{\pm }\to J/\psi {\pi }^{\pm }$ at the LHCb experiment were studied. About 310 signal events are expected for a data set which corresponds to an integrated luminosity of 1 fb${}^{-1}$, with a $B/S$ ratio equal to 2. Based on these data, the $B_c^{\pm }$ mass and lifetime can be measured with expected statistical errors below 2 MeV/$c^2$ and 30 fs, respectively.
