# Study of heavy meson production in p-Pb collisions at $\sqrt{S}$=5.02 TeV in the general-mass variable-flavour-number scheme

## TL;DR

This paper presents a next-to-leading-order analysis of charm and bottom meson production in p-Pb collisions at the LHC, showing good agreement with experimental data and no significant nuclear initial-state effects.

## Contribution

It provides the first detailed NLO calculations of heavy meson production in p-Pb collisions using the general-mass variable-flavor-number scheme, compared with recent LHC data.

## Key findings

- Good agreement with ALICE, LHCb, and CMS data
- No evidence of nuclear initial-state interaction effects
- Ratios of p-Pb to p-p cross sections close to one

## Abstract

We study inclusive charm and bottom production, for both D and B mesons, in p-Pb collisions at the LHC. Numerical results for p_T-differential production cross sections are obtained at next-to-leading-order in the general-mass variable-flavor-number scheme. We compare our results with recent data from ALICE, LHCb and CMS at a center-of-mass energy of 5 TeV and find good agreement. A comparison with p-p cross sections does not reveal the presence of nuclear initial-state interaction effects that could be expected to become visible as deviations of the ratio of p-Pb and p-p cross sections from one.
