University of Birmingham Measurement of the B+c meson lifetime using B+c J/ + X decays

The lifetime of the B + c meson is measured using semileptonic decays having a J /ψ meson and a muon in the ﬁnal state. The data, corresponding to an integrated luminosity of 2 fb − 1 , are collected by the LHCb detector in pp collisions at a centre-of-mass energy of 8 TeV. The measured lifetime is
