Measurements of Bc+ production and mass are performed with the decay mode Bc+→J/ψπ+ using 0.37fb-1 of data collected in pp collisions at √s=7TeV by the LHCb experiment. The ratio of the production cross section times branching fraction between the Bc+→J/ψπ+ and the B+→J/ψK+ decays is measured to be (0.68±0.10(stat)±0.03(syst)±0. 05(lifetime))% for Bc+ and B+ mesons with transverse momenta p T>4GeV/c and pseudorapidities 2.5
