In this talk, I will discuss in-medium jet modifications observed in heavy-ion collisions at the STAR experiment. I will also present upcoming measurements and their underlying physics at this conference.
Collision of heavy nuclei at relativistic energies provide a unique opportunity to study the behavior of strongly interacting matter under extreme conditions of temperature and density. Till date such collisions are only known way for laboratory investigation of a possible phase transition from hadronic matter to a plasma of de-confined quarks and gluons as well as the restoration of the...
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...
Exploring the in-medium properties of different mesons such as their masses and decay width may play a significant role in understanding the related experimental observables. In this work we focus on the modifications in the properties of pseudoscalar $K$ and vector $\phi$ mesons in the dense hadronic medium using the chiral SU(3) hadronic mean field model. We consider the hadronic medium...
Quantum Chromodynamics (QCD), the fundamental theory governing the strong interaction, remains a important area of study due to the ongoing challenges in fully understanding its internal dynamics, even after extensive research. Hadron spectroscopy, a specialized field within particle physics, focuses on exploring the spectrum of hadrons. This field seeks to uncover the intrinsic properties and...
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...
The mechanism responsible for (anti)nuclei production in ultrarelativistic hadronic collisions remains a subject of active scientific debate. Two leading frameworks, the statistical hadronisation model and the coalescence model, are commonly employed to interpret experimental data. In the coalescence scenario, multi-baryon states are produced when baryons that are close in phase space at...
The measurement of quarkonium production is a powerful tool for investigating both perturbative and non-perturbative aspects of quantum chromodynamics (QCD) in proton-proton (pp) collisions, as well as the properties of the quark-gluon plasma (QGP) in heavy-ion collisions. Quarkonia are golden probes of the QGP evolution, with their yields influenced by suppression and (re)generation of...
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...
Traditionally, the phase space of produced particles in relativistic heavy ion collisions has been studied in terms of Fourier basis that decompose the azimuthal distribution giving rise to the well known flow coefficients. However, very little has been done in the radial direction to analyse the transverse momentum dependence beyond simple 'eye estimation'. We introduce a systematic 2-D...
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...
The transverse momentum dependent observable $v_{0}(p_\mathrm{T})$ has recently emerged as a novel probe of radial expansion in high-energy heavy-ion collisions. Using Pb$-$Pb collision data at $\sqrt{s_\mathrm{NN}} = 5.02$ TeV recorded with the ALICE detector, measurements of $v_{0}(p_\mathrm{T})$ for pions, kaons, and protons are performed across a broad range of collision centralities. A...
We present numerical simulations of stochastic fluid dynamics with a conserved charge coupled to the momentum density of the fluid. This theory is known as model H, and it is expected to describe universal dynamics in the vicinity of a possible critical endpoint in the QCD phase diagram. We verify dynamical scaling, extract the scaling exponent z, and compute the renormalization of shear...
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...
Light (anti-)nuclei and hypernuclei are loosely bound objects whose production in high-energy collisions provides a unique window into the late-stage dynamics of the system. Their formation is typically described either through coalescence of nucleons at kinetic freeze-out or via thermal production at chemical freeze-out, and comparisons between these scenarios remain a subject of active...
Recent measurements in high-multiplicity pp and p$-$Pb collisions at the LHC have shown that small systems exhibit similar phenomena traditionally associated with heavy-ion collisions, such as strangeness enhancement, finite radial-flow and azimuthal anisotropy. These effects challenge the notion that such systems can be modelled as incoherent superpositions of parton-parton scatterings, as...
The quark-gluon plasma (QGP) produced in relativistic heavy-ion collision experiments exhibits collective behavior that can be effectively described using a relativistic hydrodynamic framework. In recent years, the experimental observation of spin polarization in various hadrons has opened a new avenue for probing the non-trivial vortical structure of the QGP medium. This has motivated the...
Inspired by a recent observation of enhancement in the dilepton rate from a magnetized QCD medium [1], we utilize a hydrodynamic model framework to incorporate the impact of the space-time evolution of the system on such properties [2]. In particular, we investigate the transverse momentum ($p_T$) spectra and even flow harmonics such as $v_2$ and $v_4$ with a focus on the impacts of the...
Wigner distributions offer a multidimensional phase–space representation of quarks, simultaneously encoding spatial and momentum correlations. They form a natural bridge between generalized parton distributions (GPDs) and transverse–momentum–dependent distributions (TMDs), providing direct access to quark orbital angular momentum (OAM). In this talk, I will present the light-front formulation...
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
dimensions, leading to rapid cooling of the medium. Consequently, it changes the dynamics of charmonium states, which is highly unlike the charmonium dynamics in heavy-ion collisions. We use...
We investigate the in-medium properties of heavy quarkonia by studying the medium modified heavy-quark potential in a hot and dense QCD medium under finite baryonic chemical potential (μb) and anisotropy (ξ). The real and imaginary components of the potential are computed using a static gluon propagator within the quasiparticle model framework. The real part is employed to solve the...
We present analytical solutions of relativistic hydrodynamics for systems with cylindrical symmetry, incorporating boost-invariant longitudinal expansion and Hubble-like transverse flow. We also discuss an analytical solution for a spherically expanding system with Hubble-like symmetry. For both cases, we calculate hadron transverse momentum spectra on a constant-temperature freeze-out...
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...
