Bottom-flavored inclusive emissions in the variable-flavor number scheme: A high-energy analysis

We propose the inclusive semihard production, in proton-proton collisions, of two bottom-flavored hadrons, as well as that of a single bottom-flavored hadron accompanied by a light jet, as novel channels for the manifestation of stabilization effects of the high-energy resummation under next-to-leading-order corrections. Our formalism relies on a hybrid high-energy and collinear factorization, where the Balitsky-Fadin-Kuraev-Lipatov (BFKL) resummation of leading and next-to-leading energy logarithms is used together with collinear factorization. We present results for cross sections and azimuthal correlations differential in rapidity, which are widely recognized as standard observables used to hunt for distinctive signals of the BFKL dynamics. We propose the study of double differential distributions in the transverse momenta of final-state particles as a common basis to investigate the interplay of different kinds of resummation mechanisms.

Automated summary

This study proposes novel channels for the manifestation of stabilization effects of high-energy resummation under next-to-leading-order corrections in proton-proton collisions, focusing on the inclusive semihard production of two bottom-flavored hadrons and a single bottom-flavored hadron accompanied by a light jet. The formalism relies on hybrid high-energy and collinear factorization, combining BFKL resummation with collinear factorization, to investigate distinctive signals of the BFKL dynamics through cross sections and azimuthal correlations. The study suggests investigating the interplay of different types of resummation mechanisms through double differential distributions in the transverse momenta of final-state particles.
