A study of prompt Xic+ production in proton-lead collisions is performed with the LHCb experiment at a center-of-mass energy per nucleon pair of 8.16 TeV in 2016 in pPb and Pbp collisions with an estimated integrated luminosity of approximately 12.5 and 17.4 nb-1, respectively. The Xic+ production cross section, as well as the Xic+ to Lambdac+ production cross-section ratio, are measured as a function of the transverse momentum and rapidity and compared to the latest theory predictions.

Abstract

A study of prompt Xic+ production in proton-lead collisions is performed with the LHCb experiment at a center-of-mass energy per nucleon pair of 8.16 TeV in 2016 in pPb and Pbp collisions with an estimated integrated luminosity of approximately 12.5 and 17.4 nb-1, respectively. The Xic+ production cross section, as well as the Xic+ to Lambdac+ production cross-section ratio, are measured as a function of the transverse momentum and rapidity and compared to the latest theory predictions. The forward-backward asymmetry is also measured as a function of the Xic+ transverse momentum. The results provide strong constraints on theoretical calculation and are a unique input for hadronization studies in different collision systems.
