Measurement of Ξ+? production in ?⁢Pb collisions at √??⁢? = 8.16 TeV at LHCb

• A study of prompt Ξ+? 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 ?⁢Pb and Pb⁢? collisions with an estimated integrated luminosity of approximately 12.5 and 17.4 nb−1, respectively. The Ξ+? production cross section, as well as the Ξ+? to Λ+? 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 Ξ+? transverse momentum. The results provide strong constraints on theoretical calculation and are a unique input for hadronization studies in different collision systems.
