The STAR experiment at RHIC has excellent detector coverage, tracking, and particle identification capabilities to study emergent phenomena of QCD, for instance the Quark-Gluon Plasma (QGP) created in central heavy-ion collisions. Among the probes used experimentally to study the QGP’s properties, hard probes (jets and heavy flavor quarks) are unique since they are dominantly produced at the...

The transition from quarks to hadrons is a fundamental process in nature that can be studied at colliders. Heavy quarks (charm and beauty) are mainly produced in hard scattering processes occurring in the early stages of the collisions, and the measurement of production yields of final-state hadrons are a sensitive tool for studying their hadronisation processes. In particular, measurements of...

In the absence of interactions the conductivity of chiral separation effect (CSE) in the system of massless fermions is given by topological expression. Interactions might change the pattern drastically. However, we prove that the CSE conductivity is still given by the topological invariant composed of the Green functions at zero temperature as long as the chiral symmetry is present, and if...

The production of the industrially significant radionuclide polonium-210 from the neutron irradiation of bismuth metal and the subsequent beta decay of bismuth-210 is highly inefficient due to the small neutron capture cross section of bismuth-209. In this paper, we report a previously undescribed self-sustaining nuclear chain reaction involving self- propagating neutron multiplication in...

The production of quarkonia in high-energy heavy-ion collisions has been studied extensively to understand their production mechanisms and properties of Quark-Gluon Plasma (QGP). The recent PHENIX study shows the increasing $J/\psi$ yields versus multiplicity in $p+p$ collisions which is similar to results in different $J/\psi$ acceptance and collision energy. These results imply that the...

Quark-Gluon Plasma (QGP) matter created in relativistic heavy-ion collisions exhibits strong collective behavior. This collectivity can be studied through the azimuthal anisotropy by the Fourier expansion of the azimuthal distributions of produced particles relative to the reaction plane. The second Fourier coefficient, elliptic flow ($v_2$), is particularly important to measure collectivity...

One of the primary goals of studying heavy-ion collisions has been to comprehend a medium of de-confined quarks and gluons called Quark-Gluon Plasma (QGP). Various nuclei, like Cu, Au, Pb, and U, have been collided in various relativistic heavy-ion colliders to decipher the properties of this medium and the corresponding particle production in these collisions. All these nuclei are observed to...

Strange hadrons offer a distinctive way to examine hadronization. Initially, the increase of the yield ratio of strange hadrons to non-strange hadrons in heavy ion collisions relative to pp collisions was the proposed signature of the quark-gluon plasma formation. The study of strangeness production from small to large collision systems is fundamental to understanding the origin of the...

The ridge effect in proton-proton and proton-lead collisions refers to the long-range near-side correlations of the final state particles in events with high particle multiplicity. In this work, we perform a comparative analysis of rapidity-azimuthal angle correlations at proton-proton collisions using Pythia and BFKLex, the latter being a Monte Carlo code based on the BFKL dynamics, the...

CMS has produced a wealth of results related to the high-density QCD matter produced in different hadronic collisions. While the heavy-ion (A-A) collisions are essential to understand collective behavior and the final-state effects for the detailed characteristics of hot, dense partonic matter, the small collision systems (p-A, p-p), provide the critical information on the initial-state cold...

Quantum Chromodynamics (QCD) predicts a transition form hadronic matter to a deconfined state of quarks and gluons known as quark gluon plasma (QGP) under extreme conditions of temperature and/or baryon chemical potential ($\mu_B$). One of the main objectives of the relativistic heavy-ion collision experiments is to explore the properties of strongly interacting QGP. Azimuthal anisotropy of...

Relative yields of quarkonium and transverse momentum (pT) spectrum of charged particles have the potential to map and test the properties of QGP medium. Inside the medium, as the quarkonia are largely exposed to the color-charge screening and gluon dissociation, the scattered partons experience a loss of energy due to gluon emission and parton splitting mainly. In this study, we evaluate the...

Studies have yielded strong evidence that a deconfined state of quarks and gluons, the quark--gluon plasma, is created in heavy-ion collisions. This hot and dense matter exhibits almost zero friction and a strong collective behavior. An unexpected collective behavior has also been observed in small collision systems. In this talk, the origin of collectivity in small collision systems is...

It is well known that strong magnetic fields arise in heavy ion collisions. The magnetic field effects essentially depend on centrality of the collision and other conditions. We study influence of external magnetic field on QCD phase diagram (temperature, chemical potential). We perform this study within holographic QCD and compare obtained results with lattice calculations available for small...
