High-energy resummed distributions for the inclusive Higgs-plus-jet production at the LHC

Abstract

The inclusive hadroproduction of a Higgs boson and of a jet, featuring large transverse momenta and well separated in rapidity, is proposed as a novel probe channel for the manifestation of the Balitsky–Fadin–Kuraev–Lipatov (BFKL) dynamics. Using the standard BFKL approach, with partial inclusion of next-to-leading order effects, predictions are presented for azimuthal Higgs-jet correlations and other observables, to be possibly compared with experimental analyses at the LHC and with theoretical predictions obtained in different schemes.

High-energy resummation in $$\Lambda _c$$ baryon production

“…The overall outcome is that the inclusive detection of c of baryons in semi-hard reactions allows for a stabilization of the high-energy resummation under higher-order corrections. A similar effect has been already observed in processes involving the production of massive bosons, such as the recently proposed Higgs plus jet channel [75]. However, while in that case the large energy scales provided by the Higgs transverse mass act as "natural" stabilizers for the BFKL series, here it comes as an intrinsic feature of the c production.…”

“…If one waives the full NLA BFKL treatment, in favor of a partial inclusion of NLA resummation effects, then also LO impact factors come into play and a plethora of new semihard channels open up, such as three-and four-jet hadroproduction [60][61][62][63][64][65][66][67][68], J/ -jet [69], forward Drell-Yan dilepton production in association with a backward-jet tag [70], heavy-quark pair photoproduction [71,72] and hadroproduction [73,74], Higgs-jet production [75].…”

Hunting BFKL in semi-hard reactions at the LHC

“…The analysis of more differential distributions covering broader kinematic ranges requires an ineludible effort into the enhancement of our formalism to accommodate other resummation mechanisms. A major outcome of a recent work on the inclusive hadroproduction of a Higgs boson and a jet well separated in rapidity [111] is that an exhaustive study of the Higgs transverse-momentum distribution lies on the exploration of neighboring kinematic regions, each of them representing a preferred channel to probe a specific resummation. That calls for a net overhaul of our framework (first from the analytic and then from the numeric point of view) which would not anymore rely only on the pure BFKL approach, but should rather evolve into an underlying staging where distinct resummations are plugged-in and play their part.…”

“…tracing the path towards a prospective NLA BFKL treatment of heavy-flavored-meson production channels. With the same accuracy, J/ -jet [110], Higgs-jet [111] and heavylight di-jet [112] correlations have been proposed, while a full LLA description, together with consistency-inspired collinear improvements [113] to the BFKL kernel, of the forward Drell-Yan dilepton production plus a backward jet has been recently conducted [114].…”

Exclusive production of $$\rho $$-mesons in high-energy factorization at HERA and EIC

“…It has been recently pointed out how the inclusive diffractive tagging of particles with a heavy transverse mass, such as Higgs bosons [38], heavy-flavored jets [39][40][41] and charmed baryons [42], leads to a fair stabilization of the high-energy series under higher-order corrections. Future studies of reactions featuring the forward emission of those objects will provide us with additional and possibly clearer probe channels for the UGD.…”
