Measurement of V0 production ratios in pp collisions at s√ = 0.9 and 7TeV
The Ā/A and Ā/K0S production ratios are measured by the LHCb detector from 0.3 nb-1 of pp collisions delivered by the LHC at s√ = 0.9TeV and 1.8 nb-1 at s√ = 7TeV. Both ratios are presented as a function of transverse momentum, pT, and rapidity, y, in the ranges 0.15 < pT < 2.50GeV/c a...

| description | The Ā/A and Ā/K0S production ratios are measured by the LHCb detector from 0.3 nb-1 of pp collisions delivered by the LHC at s√ = 0.9TeV and 1.8 nb-1 at s√ = 7TeV. Both ratios are presented as a function of transverse momentum, pT, and rapidity, y, in the ranges 0.15 < pT < 2.50GeV/c and 2.0 < y < 4.5. Results at the two energies are in good agreement as a function of rapidity loss, Δy = ybeam - y, and are consistent with previous measurements. The ratio Ā/A, measuring the transport of baryon number from the collision into the detector, is smaller in data than predicted in simulation, particularly at high rapidity. The ratio Ā/K0S , measuring the baryon-to-meson suppression in strange quark hadronisation, is significantly larger than expected. |
