The B+c meson is unique in the standard model as it is the ground state of a family of mesons containing two different heavy flavour quarks. Recent results on the B+c state are discussed and prospects of Bc studies at LHCb are described. Using the large data sample collected in 2011 at √s = 7TeV, the LHCb Collaboration achieved precise mass and production measurement of the B+c meson and reported the first observation of the B+c → J/ψ π+π−π+ and B+c → ψ(2S) π+ decay modes. Their branching fractions relative to B+c → J/ψπ+ are measured. Future studies on Bc excited states will provide a relevant input to the theoretical models of QCD-bound states involving two heavy quarks.
