A hot topic at the Large Hadron Collider (LHC) is the production of anti-nuclei. In ultra high-energy collisions, nuclei with very low binding energies are not expected to survive the dense and hot final state environment. The traditional view of nuclei production has been that antinuclei form via coalescence after the hot environment has dissipated. However, statistical thermal models, where...

The observation of collective-like behaviors in pp and p–Pb collisions at LHC energies has sparked debate about the similarities between the dynamics of small systems and heavy-ion collisions. In this talk, our latest published results are presented, showing baryon-meson v2 grouping (within 1 sigma) and significant splitting (approximately 5 sigma) at intermediate pT in high-multiplicity p–Pb...

In this work we discuss the hard dense loop perturbation theory approach for studying the thermodynamics of strongly magnetized dense quark matter. The study has been confined to one loop self-energy of quarks and gluons respectively, for calculating the free energy of the system. Thermodynamic quantities such as pressure, magnetization, second-order quark number susceptibility, and speed of...

Inspired by recent observations, we attempt to investigate the existence of a QGP-like medium in $p-p$ collisions. The $p-p$ being a small collision system implies comparable transverse and longitudinal

This interdisciplinary talk will chart the course of the quantum revolution, beginning with Richard Feynman's foundational vision of simulating nature. We will introduce the core principles of superposition, interference, and entanglement before taking a deep dive into the leading hardware platforms, including superconducting and trapped-ion qubits. The presentation will discuss some...

Jet is a collimated shower of particles produced from the fragmentation of high energetic partons in high energy collisions. Jet measurements provide a testing ground of the pQCD calculations while in heavy-ion collisions they help to probe the medium. In this talk I will focus on the recent results of jet measurements at LHC. The recent interesting results from small collision systems will...

Over the past 15 years, elliptic and triangular flow coefficients ($v_2$, $v_3$) have been extensively studied in heavy-ion collisions to gain insight into the collective behavior and transport properties of the quark-gluon plasma (QGP). However, in recent years, increasing attention has been directed toward the radial and directed flow coefficients ($v_0$, $v_1$), which have emerged as...

Dilepton emissions represent a key probe for characterising the Quark-Gluon Plasma (QGP). A central role in computing dilepton yields is played by the imaginary part of the electromagnetic current-current correlation, or equivalently, of the photon polarisation tensor [1]. In this work, we investigate the influence of local acceleration on dilepton production. We compute this quantity in a...

The surface tension under one loop correction at finite chemical potential is calculated. Due to the effect of the chemical potential in this one loop correction, the formation of stable bubble/droplet is obtained with the value of quark and gluon parametrization in the range of gamma_{q} = 1/8 and 24 gamma_{q} less than and equal to gamma_{g} less tahn and equal to 30 gamma_{q}. It implies...
