Recent developments in heavy flavour production

TL;DR

This paper reviews recent theoretical and experimental progress in heavy-flavour hadron production, emphasizing resummation techniques, mass dependence, and comparisons with collider data for charm and bottom mesons.

Contribution

It introduces a framework that resums collinear logarithms and retains heavy-quark mass dependence, providing improved predictions for heavy-flavour production.

Findings

Good agreement with CDF data for charmed and B-meson production.

Effective description of D* meson photoproduction at HERA.

Validation of the resummation approach against experimental results.

Abstract

We review one-particle inclusive production of heavy-flavoured hadrons in a framework which resums the large collinear logarithms through the evolution of the FFs and PDFs and retains the full dependence on the heavy-quark mass without additional theoretical assumptions. We focus on presenting results for the inclusive cross section for the production of charmed mesons in p anti-p collisions and the comparison with CDF data from the Tevatron as well as on inclusive B-meson production and comparison with recent CDF data. The third topic is the production of D^* mesons in photoproduction and comparison with recent H1 data from HERA.
