Heavy long-lived quarks, ie charm and bottom, are frequently studied both as tests of QCD
and as probes for other physics aspects within and beyond the standard model. The long …

We propose a new analytical expression for the transverse-momentum-dependent (TMD, or
unintegrated) gluon density in the proton. Essential phenomenological parameters are …

Using the analytical expression for transverse momentum dependent (TMD) gluon density in
a proton, a self-consistent simultaneous description of low Q 2 data on proton structure …

In the hadroproduction of charm in the context of string fragmentation, the pull of a beam
remnant at the other end of a string may give a charm hadron more energy than the …

Simple interpolating formula for the square of the quarkonium mass and an analytic
expression for the Regge trajectories α (t) in a whole region of both light and heavy …

We discuss the open charm production in the peripheral reactions p¯ p→ Y¯ c Y c and p¯
p→ M c M¯ c, where Y c and M c stand for Λ c+, Σ c+ and D, D*, respectively, at s≲ 15 GeV …

Hadron inclusive spectra in pp collisions are analyzed within the modified quark–gluon
string model including both the longitudinal and transverse motion of quarks in the proton in …

We find out the connection between the unintegrated gluon distribution at low intrinsic
transverse momenta and the inclusive spectrum of the hadrons produced in pp collision at …

Transverse momentum dependent (TMD) parton distributions in a proton are important in
high-energy physics from both theoretical and phenomenological points of view. Using the …

We use a nonperturbative QCD approach, the quark-gluon string model, to compute the τ-
neutrino fluxes produced by fixed target pA collisions (where A is a target material) for …
