I will present a new strategy [1] to analyze the chemical freeze-out of light (anti)nuclei produced in high energy collisions of heavy atomic nuclei within an advanced version of the hadron resonance gas model. It is based on two different, but complementary approaches to model the hard-core repulsion between the light nuclei and hadrons. The first approach is based on an approximate...
Traditionally, low-$p_\perp$ sector is used to infer the features of initial stages of QGP evolution before QGP thermalization. On the other hand, recently acquired wealth of high-$p_{\perp}$ experimental data paves the way to utilize the hard probes energy loss in exploring the initial stages. We here study [1] how four different commonly considered initial-stage scenarios – which have the...
The equation of state (EoS) of quark-gluon plasma (QGP) using a phenomenological model is studied with magnetic field effect. The calculations with the effective mass of quark are modified in the presence of magnetic field. The results presented using thermodynamic variables are significantly affected by effective quark mass and with the magnetic field. The model results provide EoS of QGP...
We study the two photon decays using a phenomenological model emitted from a quark-gluon plasma at high temperature. For the phenomenology of heavy-ion collisions, we present γγ emission spectra by taking into account the parametrization factors in thermal dependent quark mass. The rate of diphoton production is calculated and compared with the rate from hadronic matter. The production rate is...
Anisotropic flow is used to study the key properties and the evolution of the quark-gluon plasma (QGP) created in heavy-ion collisions and to search for a small droplet of QGP in small collision systems. One of the ways of studying these phenomena is via multi-particle cumulants of different orders. Currently, only a few of them are available and have been studied in theoretical calculations...
Induced Surface and Curvature Tensions approach for 3D and 2D multicomponent dense mixtures of hard spheres
Results for classical case and thoughts about its generalization using Lorentz contraction of excluded volume
The PHENIX experiment takes full advantage of polarized proton collisions provided by the Relativistic Heavy Ion Collider to probe the spin structure of the proton. The PHENIX Spin program studies the gluon and sea quark helicity distributions as well as transverse spin phenomena via various spin observables using longitudinally and transversely polarized proton collisions.
In addition,...
