Abstract Effects of non-linear small-x evolution of the gluon distribution given by the Balitsky–Kovchegov equation are analyzed within the collinear approximation framework. We perform a twist decomposition of the proton structure functions $$F_2$

We investigate production of J/ψ mesons in hadron-hadron collisions, defined as low invariant mass cc¯ singlets produced in a mixture of perturbative and nonperturbative mechanisms provided by the PYTHIA Monte Carlo. We find that in this model the

Abstract In the hybrid k T -factorization formula, one initial-state parton momentum is space-like and carries non-vanishing transverse components, while the other is on-shell. We promote this factorization formula to next-to-leading order. Studying

Abstract We present theoretical predictions for selected differential cross sections for the process $$pp \rightarrow t {\bar{t}}B$$ pp→tt¯B at the LHC, where B can be a Higgs (H), a Z or a W boson. The predictions are calculated in the direct QCD

Abstract We analyze contributions to the heavy vector meson production with large transverse momentum in proton-proton and diffractive photon-proton scattering driven by an exchange of two Balitsky-Fadin-Kuraev-Lipatov Pomerons in the squared amplitu

Abstract We perform threshold resummation of soft gluon corrections to the total cross sections and the invariant mass distributions for production of a top-antitop quark pair associated with a heavy electroweak boson $$V = W^+$$ V=W+ , $$W^-$$ W- or

Abstract We propose a new process which probes the BFKL dynamics in the high energy proton-proton scattering, namely the forward Drell-Yan (DY) production accompanied by a backward jet, separated from the DY lepton pair by a large rapidity interval.

Abstract The combined HERA data for the inclusive deep inelastic scattering (DIS) cross sections for the momentum transfer $$Q^2 > 1\,\mathrm {GeV}^2$$ Q2>1GeV2 are fitted within the Dokshitzer–Gribov–Lipatov–Altarelli–Parisi (DGLAP) framewor

The studies of the associated production processes of a top-quark pair with a colour-singlet boson, e.g. Higgs, W or Z, are among the highest priorities of the LHC programme. Correspondingly, improvements in precision of theoretical predictions for t
