Prompt and non-prompt J/psi production and nuclear modification at mid-rapidity in p-Pb collisions at root s(NN)=5.02 TeV
Original language description
A measurement of beauty hadron production at mid-rapidity in proton-lead collisions at a nucleon-nucleon centre-of-mass energy root s(NN) = 5.02 TeV is presented. The semi-inclusive decay channel of beauty hadrons into J/psi is considered, where the J/psi mesons are reconstructed in the dielectron decay channel at mid-rapidity down to transverse momenta of 1.3 GeV/c. The bb production cross section at mid-rapidity, d sigma(bb)/dy, and the total cross section extrapolated over full phase space, sigma(bb), are obtained. This measurement is combined with results on inclusive J/psi production to determine the prompt J/psi cross sections. The results in p-Pb collisions are then scaled to expectations from pp collisions at the same centre-of-mass energy to derive the nuclear modification factor R-pPb, and compared to models to study possible nuclear modifications of the production induced by cold nuclear matter effects. RpPb is found to be smaller than unity at low pT for both J/psi coming from beauty hadron decays and prompt J/psi.
