Description
In this talk we present our theoretical results for the single-diffractive production of open heavy flavor mesons and non-prompt charmonia in pp and pA collisions. Using the color dipole framework, we found that this mechanism 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 should be significantly slower than that of inclusive production of the same heavy mesons. If this expectation will be confirmed experimentally, this could constitute important contribution to our understanding of multiplicity enhancement mechanisms in the production of different quarkonia states. We also analyzed this process in pA collisions and found that the cross-section per nucleon decerases by up to a factor of two compared to pp production due to nuclear saturation effects.
