Single diffractive production of open heavy flavor mesons

In this paper, we discuss the single diffractive production of open heavy flavor mesons and nonprompt charmonia in 𝑝⁢𝑝 collisions. Using the color dipole approach, we found that the single diffractive production constitutes 0.5%–2% 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 coproduced hadrons and found that it is significantly slower than that of inclusive production of the same heavy mesons.
