Hadrons anti-hadrons production in reaction planes in relativistic heavy ion collisions on two common event generators: HIJING and HYDJET++

open access: yesEPJ Web of Conferences, 2017
The study of hadron production in heavy ion collisions provides the researcher with valuable techniques to investigate the properties of quark gluon plasma (QGP).

Analysing powers and spin correlations in deuteron–proton charge exchange at 726 MeV

open access: yesPhysics Letters B, 2015
The charge exchange of vector polarised deuterons on a polarised hydrogen target has been studied in a high statistics experiment at the COSY-ANKE facility at a deuteron beam energy of Td=726 MeV. By selecting two fast protons at low relative energy Epp,

Hadron Spin Dynamics [PDF]

open access: yes, 2001
Spin effects in exclusive and inclusive reactions provide an essential new dimension for testing QCD and unraveling hadron structure. Remarkable new experiments from SLAC, HERMES (DESY), and the Jefferson Laboratory present many challenges to theory ...

Compressible bag model and the phase structure

open access: yes, 2002
The phase structure of hadrons and quark-gluon plasma is investigated by two types of equation of hadron state, namely ideal hadron gas model and the compressible bag model.

Evaluation of the two lightest quark masses

open access: yesЯдерна фізика та енергетика, 2017
Simple relations between the masses of the two lightest up and down quarks were obtained on the basis of the simple physically based model compatible with the present-day theory of strong interactions, i.e. with quantum chromodynamics.

Forward rapidity J/ψ production as a function of charged-particle multiplicity in pp collisions at s $$ \sqrt{s} $$ = 5.02 and 13 TeV

open access: yesJournal of High Energy Physics, 2022
The production of J/ψ is measured as a function of charged-particle multiplicity at forward rapidity in proton-proton (pp) collisions at center-of-mass energies s $$ \sqrt{s} $$ = 5.02 and 13 TeV.

Quarkonium polarization as a test of non-relativistic effective theory [PDF]

open access: yes, 1997
I compare current approaches to quarkonium production with regard to what they tell us about quarkonium polarization. Predictions for $J/\psi$ polarization in hadron-hadron and photon-hadron collisions are summarized.Comment: 6 pages, LaTeX, 3 figures ...

Semi-inclusive photon-hadron production in pp and pA collisions at RHIC and LHC

open access: yes, 2012
We investigate semi-inclusive photon-hadron production in the color glass condensate (CGC) framework at RHIC and the LHC energies in proton-proton (pp) and proton-nucleus (pA) collisions. We calculate the coincidence probability for azimuthal correlation

On the nature of the N* and Δ resonances via coupled-channel dynamics [PDF]

open access: yesEPJ Web of Conferences
This talk focuses on a recent work aiming at determining the composition of certain N* and Δ resonances, i.e. whether they are compact states formed directly by quarks and gluons, or composite generated from the mesonbaryon interaction.

Restoration of $k_T$ factorization for low $p_T$ hadron hadroproduction

open access: yes, 2011
We discuss the applicability of the $k_T$ factorization theorem to low-$p_T$ hadron production in hadron-hadron collision in a simple toy model, which involves only scalar particles and gluons. It has been shown that the $k_T$ factorization for high-$p_T$
