Various nuclei, like Cu, Au, Pb, and U, have collided in various relativistic heavy-ion colliders to comprehend the medium of de-confined quarks and gluons called Quark-Gluon Plasma (QGP). The STAR data for isobar, Ru+Ru, and Zr+Zr, collisions at $\sqrt{s_{\mathrm {NN}}}$ = 200 GeV, provide hints of different nuclear structure between the two isobar nuclei through collective flow and...
n this talk I wish to clarify two questions that have been left unanswered in the paper D.Kharzeev and E. Levin:
``Deep inelastic scattering as a probe of entanglement,''
Phys. Rev. D \textbf{95} (2017) no.11, 114008.
In this paper we compute the von Neumann entropy of the system of partons resolved by deep inelastic scattering at a given Bjorken $x$ and momentum transfer $q^2 = - Q^2$. ...
In this talk we briefly overview various channels used for phenomenological studies of the partonic structure of the target, which is usually encoded in Generalized Parton Distributions (GPDs), and also summarize our recent theoretical studies of exclusive production of heavy mesons pairs (quarkonia and heavy-light $D$-mesons). We argue that at moderate energies (for example, in the kinematics...
It was argued that local parity breaking may emerge in hot dense hadronic medium. We investigate the possibility of formation of photon and vector meson states localized in the transition region between domains with different axial chemical potential values. Using the vector meson dominance model modified to take into account parity-breaking backgrounds we obtain the spectrum of such states...
Relativistic procedure of explicit accounting of the orbital momentum and
spin of the $V$-meson resonance
is suggested for the high energy inclusive reaction
$A+B\Longrightarrow V+X\Longrightarrow 1+2+X$.
It is compared decays of the structureless and composite $V$-mesons.
Composite mesons are constructed within to the general field-theoretical
approach,
where hadrons and...
High-energy collisions allow us to study the behaviour of matter at high temperature and density. Various experimental signatures suggest that a new state of matter called Quark-Gluon Plasma (QGP) is produced in heavy-ion collisions. However, recent results suggest that high-multiplicity $p$+$p$ collisions might also be able to produce QGP droplets. Therefore, there is a pressing need to gain...
High-energy heavy-ion collision experiments aim to explore the phase transition from normal hadronic matter to the quark-gluon plasma (QGP), a deconfined state of quarks and gluons. The dynamics of relativistic heavy-ion collisions at various collision energies have been extensively studied using A Multi-Phase Transport (AMPT) model. The AMPT model is very sensitive to the input parameters,...
We present a novel method of extraction of the Collins-Soper kernel directly from the comparison of differential cross-sections measured at different energies. Using this method, we provide feasibility studies for the direct measurement of the Collins-Soper kernel with the CMS detector. We also solve a long standing problem of comparison between TMDs obtained from PB and factorization approaches.
We fit the transverse momentum spectra of hadrons from intermediate heavy-ion collisions, generated by two microscopic transport models, UrQMD and SMASH, to Boltzmann-Gibbs and to Tsallis distributions. The analysis is done (i) for the evolution of hot and dense nuclear matter in central area of central heavy-ion collisions and (ii) for the infinite nuclear matter, simulated in both models via...
We study a bino-like light neutralino ($\tilde \chi_1^0$) produced at the LHC from the decay of a scalar lepton ($\tilde e_L$) through the process $pp\to \tilde e_{L} \to e\tilde \chi_1^0$ in the context of R-parity-violating (RPV) supersymmetry where $\tilde \chi_1^0$ is the lightest supersymmetric particle. For small masses and RPV couplings, the neutralino is naturally long-lived and its...
