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