“…It is known that various expressions for C n , equivalent in the NLA BFKL approximation, exist (for an extensive study of them and of their peculiarities, see Ref. [46]). For the purposes of the analysis proposed in this work, it is sufficient to consider just one representation, the so-called exponentiated one, where the following global for-(2021) 81:691 mula for the C n ≡ C NLA n coefficients holds with NLA BFKL accuracy:…”

“…A potential issue, highlighted first [46] in the case of Mueller-Navelet jet production (left panel of Fig. 2) but present in any process featuring jet emission in the final state, is related with the experimental event selection in a situation when more than one jet is tagged in a single event.…”

“…In particular, jet impact factors have been widely employed to describe the inclusive hadroproduction of two jets tagged with high transverse momenta and large separation in rapidity (Mueller-Navelet configuration [38]), for which several phenomenological studies have been carried out so far [39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54]. The comparison of theoretical distributions on the azimuthalangle distance between the two jets, ϕ = ϕ J 1 − ϕ J 2 − π , with experimental analyses [55] recently conducted by the Compact-Muon-Solenoid (CMS) collaboration at Cern, has addressed projections on azimuthal-angle observables and ratios between any two of them, R n0 ≡ cos(nϕ) , R nm ≡ cos(nϕ) cos(mϕ) ,…”

The agreement between calculations inspired by the resummation of energy logarithms, known as BFKL approach, and experimental data in the semi-hard sector of QCD has become manifest after a wealthy series of phenomenological analyses. However, the contingency that the same data could be concurrently portrayed at the hand of fixed-order, DGLAP-based calculations, has been pointed out recently, but not yet punctually addressed. Taking advantage of the richness of configurations gained by combining the acceptances of CMS and CASTOR detectors, we give results in the full next-to-leading logarithmic approximation of cross sections, azimuthal correlations and azimuthal distributions for three distinct semi-hard processes, each of them featuring a peculiar final-state exclusiveness. Then, making use of disjoint intervals for the transverse momenta of the emitted objects, i.e. $$\kappa $$ κ -windows, we clearly highlight how high-energy resummed and fixed-order driven predictions for semi-hard sensitive observables can be decisively discriminated in the kinematic ranges typical of current and forthcoming analyses at the LHC. The scale-optimization issue is also introduced and explored, while the uncertainty coming from the use of different PDF and FF set is deservedly handled. Finally, a brief overview of , a numerical tool recently developed, suited for the computation of inclusive semi-hard reactions is provided.

“…These reactions include (see also Ref. [33]) the diffractive leptoproduction of two light vector mesons [23,[34][35][36], the inclusive hadroproduction of two jets featuring large transverse momenta and well separated in rapidity (Mueller-Navelet channel [37]), for which several phenomenological analyses have appeared so far [38][39][40][41][42][43][44][45][46][47][48][49][50][51], the inclusive detection of two light-charged rapidity-separated hadrons [52][53][54][55] or of a rapidity-separated pair formed by a light-charged hadron and a jet [56][57][58], the inclusive production of rapidity-separated -or -jet pairs [59]. For all these hadroproduction channels a hybrid highenergy/collinear factorization was built up, where collinear parton distribution functions (PDFs) enter the definition of the BFKL impact factors.…”

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

We present a study on inclusive emissions of a double $$\Lambda _c$$ Λ c or of a $$\Lambda _c$$ Λ c plus a light-flavored jet system as probe channels in the semi-hard regime of QCD. Our formalism relies on the so-called hybrid high-energy/collinear factorization, where the standard collinear description is supplemented by the t-channel resummation à la BFKL of energy logarithms up to the next-to-leading accuracy. We make use of the modular interface, suited to the analysis of different semi-hard reactions, employing the novel parameterization for the description of parton fragmentation into $$\Lambda _c$$ Λ c baryons. We provide predictions for rapidity distributions and azimuthal correlations, that can be studied at current and forthcoming LHC configurations, hunting for possible stabilizing effects of the high-energy series.

The decorrelation in the azimuthal angle between the most forward and the most backward jets (Mueller-Navelet jets) is measured in data collected in pp collisions with the CMS detector at the LHC at √ s = 7 TeV. The measurement is presented in the form of distributions of azimuthal-angle differences, ∆φ, between the Mueller-Navelet jets, the average cosines of (π − ∆φ), 2(π − ∆φ), and 3(π − ∆φ), and ratios of these cosines. The jets are required to have transverse momenta, p T , in excess of 35 GeV and rapidities, |y|, of less than 4.7. The results are presented as a function of the rapidity separation, ∆y, between the Mueller-Navelet jets, reaching ∆y up to 9.4 for the first time. The results are compared to predictions of various Monte Carlo event generators and to analytical predictions based on the DGLAP and BFKL parton evolution schemes.
