The quark-gluon plasma (QGP), a new state of nuclear matter at extremely high temperature and pressure where quarks and gluons are deconfined can be produced in relativistic heavy-ion collisions. Experimentally QGP is regularly produced in the laboratory by colliding ions in relativistic energy to create such an extreme temperature and pressure. An extensive study of the formation of the QGP...
The Multi-Purpose Detector (MPD) experiment is a flagship heavy-ion experiment at the NICA facility under construction at JINR, in Dubna, Russia expected to start operation in 2025. The experiment will operate in the energy range √sNN = 4-11 GeV which covers the high net-baryon density region of the QCD phase diagram. Among the various physics topics covered by the MPD physical program,...
Transverse momentum-dependent parton distributions (TMDs) factorization is a peculiar theoretical framework in QCD which aids in understanding the high-energy scattering processes. Techniques such as collinear factorization, Qiu-Sterman, soft-collinear effective theory, lattice QCD and Gaussian approximation have been employed for factorization in bag model, light-front constituent quark...
We formulate a light-front spectator model for the proton incorporating the gluonic degree of freedom. In this model, at high energy scattering of the proton, the active parton is a gluon and the rest is viewed as a spin-1/2 spectator with an effective mass. The light front wave functions of the proton are constructed using a soft wall AdS/QCD prediction and parametrized by fitting the...
In this work, we inspect the susceptibilities of the conserved charges like charge number, baryon number, and strangeness number using the Polyakov loop extended quark meson model. The effect of a finite magnetic field is studied on the fluctuations for the zero value of the chemical potential by employing Taylor's series expansion method. The impact of the finite magnetic field on the...
The method of superoperators in Liouville space was applied to study equilibrium and excited states of hot nuclei. By the example of selected iron group nuclei and neutron-rich nuclei with N$\approx$50, the influence of temperature on the rates and cross sections for various weak-interaction reactions (electron capture, inelastic neutrino scattering, etc.), which play an important role in the...
We study the global properties of a star made of self-gravitating Bose-Einstein Condensates Rastall, Rainbow and combined Rastall-Rainbow theories of modified gravity. By employing a relativistic and non-relativistic BEC equation of state we solve the stellar structure equations in these theories and quantify the mass and radius of the BEC stars. We also study the effect temperature on BEC...
To portray the internal structure of low-lying octet baryons, the understanding of the intrinsic properties of their building blocks i.e., quarks and gluons is indispensable. We present the study of spatial distribution of quark charges via generalized parton distribution in the impact parameter space. This structural anatomization is carried out by making the use of quark-scalar diquark model...
