Abstract: (APS)

A study of prompt

Ξ_{c}^{+}

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

p Pb

and

Pb p

collisions with an estimated integrated luminosity of approximately 12.5 and 17.4

{nb}^{- 1}

, respectively. The

Ξ_{c}^{+}

production cross section, as well as the

Ξ_{c}^{+}

to

Λ_{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

Ξ_{c}^{+}

transverse momentum. The results provide strong constraints on theoretical calculation and are a unique input for hadronization studies in different collision systems.
