Abstract

The production of bmesons in proton-proton collisions is studied using a data sample collected by the LHCb detector, at centre-of-mass energies of s$$ \sqrt{s} $$=7 and 8 TeV and corresponding to an integrated luminosity of 3.0 fb1. The bmesons are identified through their decays to (1S) and (2S) using photons that converted to e+e pairs in the detector. The relative prompt production rate of b1(1P) and b2(1P) mesons is measured as a function of the (1S) transverse momentum in the brapidity range 2.0 < y <4.5. A precise measurement of the b(3P) mass is also performed. Assuming a mass splitting between the b1(3P) and the b2(3P) states of 10.5 MeV/c2, the measured mass of the b1(3P) meson is
