Charm production in fixed-target mode at LHCb

Being used in the fixed-target mode, the multi-TeV LHC proton and lead beams allow for studies of heavy-flavour hadroproduction with unprecedented precision at backward rapidities, far negative Feynman-x, using conventional detection techniques. At the nominal LHC energies, quarkonia can be studied in detail inp+p,p+d, andp+Acollisions atsNN≃115 GeV and in Pb +pand Pb +Acollisions atsNN≃72 GeV with luminosities roughly equivalent to that of the collider mode that is up to 20 fb−1 yr−1inp+pandp+dcollisions, up to 0.6 fb−1 yr−1inp+Acollisions, and up to 10 nb−1 yr−1in Pb +Acollisions. In this paper, we assess the feasibility of such studies by performing fast simulations using the performance of a LHCb-like detector.

The Impact

Selected results of the LHCb experiment on heavy ion collisions studied in the collider and fixed-target modes are presented. The clear evidence of the impact of the production mechanism (prompt/delayed, p-p or p-Pb systems) on the pT and rapidity distributions for J/ф, D0 and ϒ(ns) species is demonstrated. The interpretation of the observations in frames of theoretical models is briefly discussed. Some original results, as well as prospects of fixed-target mode studies, are presented.
