Abstract

The charged-particle production ratios are measured with the LHCb detector using 0.3 nb-1 of pp collisions delivered by LHC at sqrt(s)=0.9 TeV and 1.8 nb-1 at sqrt(s)= TeV. The measurements are performed as a function of transverse momentum pT and pseudorapidity eta. The production ratios are compared to the predictions of several Monte Carlo genera- tor settings, none of which are able to describe adequately all observables. The ratio anti-p/p is also considered as a function of rapidity loss, Delta-y = y_beam - y, and is used to constrain models of baryon transport.
