Abstract

The cross-sections of (2) meson production in proton-proton collisions at √=13 TeV are measured with a data sample collected by the LHCb detector corresponding to an integrated luminosity of 275 pb−1. The production cross-sections for prompt (2) mesons and those for (2) mesons from b-hadron decays ((2)-from- ) are determined as functions of the transverse momentum, T, and the rapidity, y, of the (2) meson in the kinematic range 2<T<20 GeV/ and 2.0<<4.5. The production cross-sections integrated over this kinematic region are( prompt (2),13 TeV)=1.430±0.005 (stat)±0.099 (syst)μb,((2)-from- ,13 TeV)=0.426±0.002 (stat)±0.030 (syst)μb.A new measurement of (2) production cross-sections in pp collisions at √=7 TeV is also performed using data collected in 2011, corresponding to an integrated luminosity of 614 pb−1. The integrated production cross-sections in the kinematic range 3.5<T<14 GeV/ and 2.0<<4.5 are( prompt (2),7 TeV)=0.471±0.001 (stat)±0.025 (syst)μb,((2)-from- ,7 TeV)=0.126±0.001 (stat)±0.008 (syst)μb.All results show reasonable agreement with theoretical calculations.
