b-Hadron production in the general-mass variable-flavour-number scheme and LHC data

TL;DR

This paper presents theoretical predictions for inclusive b-hadron production at the LHC using the general-mass variable-flavour-number scheme, showing good agreement with experimental data and highlighting minor discrepancies in cross section ratios across energies.

Contribution

It introduces a detailed theoretical framework for b-hadron production and compares it with LHC data, revealing areas of agreement and tension.

Findings

Predictions agree with LHCb and CMS data within uncertainties.

Minor tension observed in cross section ratios at different energies.

Theoretical uncertainties are primarily due to renormalization scale variations.

Abstract

We study inclusive b-hadron production in pp collisions at the LHC at different center-of-mass energies and compare with experimental data from the LHCb and CMS collaborations. Our predictions for cross sections differential in the transverse momentum and (pseudo-)rapidity agree with data within uncertainties due to renormalization scale variations. A small tension is found if data and theory predictions are compared for cross section ratios at different center-of-mass energies.
