TL;DR

This paper investigates the production of open heavy flavor mesons and non-prompt charmonia in proton-proton collisions using the color dipole approach, revealing their production rates and dependence on collision energy and multiplicity.

Contribution

It introduces a detailed analysis of single diffractive production of heavy mesons in $pp$ collisions, providing theoretical predictions aligned with experimental data and exploring multiplicity effects.

Findings

Single diffractive production is 0.5-2% of inclusive production.

Theoretical results agree with Tevatron data.

Cross-section at LHC energies is experimentally accessible.

Abstract

In this paper we discuss the single diffractive production of open heavy flavor mesons and non-prompt charmonia in $pp$ collisions. Using the color dipole approach, we found that the single diffractive production constitutes 0.5-2 per cent of the inclusive production of the same mesons. In Tevatron kinematics our theoretical results are in reasonable agreement with the available experimental data. In LHC kinematics we found that the cross-section is sufficiently large and could be accessed experimentally. We also analyzed the dependence on multiplicity of co-produced hadrons and found that it is significantly slower than that of inclusive production of the same heavy mesons.
