Measurement of ${\Xi }_c^{+}$ production in $p\mathrm{Pb}$ collisions at $\sqrt{s_{NN}}=8.16$ TeV at LHCb

A study of prompt ${\Xi }_c^{+}$ production in proton-lead collisions is performed with the LHCb experiment at a center-of-mass energy per nucleon pair of 8.16 $\text{TeV}$ in 2016 in $p\mathrm{Pb}$ and $\mathrm{Pb}p$ collisions with an estimated integrated luminosity of approximately 12.5 and 17.4 ${\text{nb}}^{-1}$, respectively. The ${\Xi }_c^{+}$ production cross section, as well as the ${\Xi }_c^{+}$ to ${\Lambda }_c^{+}$ 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 ${\Xi }_c^{+}$ transverse momentum. The results provide strong constraints on theoretical calculation and are a unique input for hadronization studies in different collision systems.
