Up to now, the existence of intrinsic (or valence-like) heavy quark components of the proton distribution function has not yet been confirmed or rejected. We show that this hypothesis can be verified at experiments on the inclusive production of the open strangeness (NA61) and at measurements of prompt photons or vector bosons accompanied by heavy flavour jets performed at LHC, CERN. Our theoretical study demonstrates that investigations of the intrinsic heavy quark contributions look very promising in hard processes like $pprightarrow K^pm+X$ and $pprightarrowgamma/Z/W +c(b)+X$. A possible observation of these components at the CBM, NICA experiments is discussed also.
The production of heavy flavour hadrons in $pp$ collisions at large values of their transverse momenta can be a new unique source for estimation of intrinsic heavy quark contribution to the proton. We analyze the inclusive production of the open stra
Exact analytical forms of solutions for Dispersion Relations for Amplitudes and Dispersion Relations for Slopes are applied in the analysis of pp and $rm {p bar p}$ scattering data in the forward range at energies below $sqrt(s)approx 30 GeV$. As inp
We analyze the self-similarity approach applied to study the hadron production in p-p and A-A collisions. This approach allows us to describe rather well the ratio of the proton to anti-proton yields in A-A collisions as a function of the energy at a
We present theoretical model comparison with published ALICE results for D-mesons (D$^0$, D$^+$ and D$^{*+}$) in $p$+$p$ collisions at $sqrt{s}$ = 7 TeV and $p$+Pb collisions at $sqrt{s_{NN}}$ = 5.02 TeV. Event generator HIJING, transport calculation
We study the correlations of D mesons produced in $p$+$p$ and $p$+Pb collisions. These are found to be sensitive to the effects of the cold nuclear medium and the transverse momentum ($p_T$) regions we are looking into. In order to put this on a quan
