文摘In this paper a feasibility study of the Bc meson to measure its mass and lifetime is described with the general purpose detector at the LHC. The study solely concentrated on the J/ψn^＋, J/ψ→μ^＋μ^- decay channel of the Bc and it was concluded that about 120 events can be selected in the first fb^-1 of data. With this data sample, the mass resolution was estimated to be 2.0（stat.） MeV/c^2 while the cτ resolution was found to be 13.1（stat.） p.m, i.e. the lifetime resolution to be 0.044（stat.） ps.
