Measurement of production cross-sections in proton-proton collisions at and

The cross-sections of meson production in proton-proton collisions at are measured with a data sample collected by the LHCb detector corresponding to an integrated luminosity of . The production cross-sections for prompt mesons and those for mesons from b -hadron decays () are determined as functions of the transverse momentum, , and the rapidity, y , of the meson in the kinematic range and . The production cross-sections integrated over this kinematic region are A new measurement of production cross-sections in pp collisions at is also performed using data collected in 2011, corresponding to an integrated luminosity of . The integrated production cross-sections in the kinematic range and are All results show reasonable agreement with theoretical calculations.
