9. Impact of Spin on Quark Wigner Distributions

SUJIT JANA (SVNIT)

04/09/2025, 16:40

Poster

We study how the spin of quarks and the target affects the shape of Wigner distributions in the transverse impact parameter space $(\vec{b}_\perp)$, which is conjugate to the transverse momentum transfer $D_\perp=\frac{\Delta_\perp}{1-\xi^2}$, within the framework of a light-front dressed quark model. This study considers the effect of nonzero longitudinal momentum transfer, called skewness,...

17. Mass bounds for fully bottom tetraquark from Regge phenomenology driven inequalities

Vandan Patel (Sardar Vallabhbhai National Institute of Technology Surat, Gujarat, India)

04/09/2025, 16:40

Poster

We present a study of the mass spectrum of fully bottom ($bb\bar{b}\bar{b}$) tetraquark states using a Regge phenomenology-based approach. Interpreting these tetraquarks as diquark–antidiquark bound systems, we employ quasi-linear Regge trajectories in the ($J,M^2$) plane to examine their mass behavior. Within this framework, we establish linear and quadratic mass inequalities that impose...

38. The Diquark-Antidiquark Picture of Kaon-like Resonances

Chetan Lodha

Poster

Motivated by the discovery of several kaon-like states observed at BESIII and LHCb, this study explores S, P and D wave tetraquark states with quark contents $ss\bar{s}\bar{q}$ and $sq\bar{q}\bar{q}$ using potential-based phenomenology. The tetraquarks are modeled as diquark-antidiquark systems in $[\bar{3}]_c \otimes [3]_c$ and $[6]_c \otimes [\bar{6}]_c$ color configurations. A comparison...

15. Coalescence Like Sum Rules from Hydrodynamics

Ms Priya (Indian Institute of Science Education and Research, Berhampur)

04/09/2025, 16:50

Poster

Hadronization in ultra-relativistic heavy-ion collision (UHIC) experiments can be effectively described by the quark coalescence mechanism. Within this framework, sum rules for flow coefficients naturally emerge, wherein the flow harmonic $v_n$ of a hadron is expressed as the sum of the corresponding $v_n$ of its constituent quarks. The application of these sum rules requires the consideration...

34. Two-body nonleptonic decays of D, Ds, B and Bs mesons in the factorization approach: Theoretical predictions for heavy-ion physics applications

Manakkumar Parmar (Sardar Vallabhbhai National Institute of Technology, Surat)

04/09/2025, 16:50

Poster

Heavy flavor mesons serve as crucial probes of the Quark-Gluon Plasma (QGP) in heavy-ion collisions at RHIC and LHC facilities. Precise theoretical predictions of their decay properties in vacuum are essential baseline measurements for understanding medium modifications in hot QCD matter. Using the factorisation approach, this work presents a comprehensive study of two-body nonleptonic decays...

2. When Stars Collapse in Silence: Magnetar-Black Hole Variability Under the Veil of Dark Matter

Anmol Gandhi (Independent Researcher)

04/09/2025, 16:50

Poster

Magnetars, a rare class of neutron stars, are known for their ultra-strong magnetic fields and high-energy emission variability. Their origin, evolution, and interactions especially with black holes present unique challenges to astrophysical models. This study investigates the dynamic behavior of magnetar–black hole systems, focusing on how hidden dark matter, either distributed in their local...

42. Effect of viscosity on jet thermalization in hot QCD plasma.

Sally Rodrigues

04/09/2025, 17:00

Poster

We perform numerical investigations in the framework of QCD kinetic theory to examine the energy and angular characteristics of high energetic parton, acting as representative for a jet formed in heavy-ion collisions. The parton traverses through Quark-Gluon Plasma (QGP), enabling us to analyze the behavior of the medium. The parton’s energy loss, arising from medium-induced radiation, is...

33. Meson Mass Modifications in Hot and Dense QCD Matter via a Complex Heavy-Quark Potential

DIPESH YADAV (SVNIT)

04/09/2025, 17:00

Poster

We present a method to determine the masses of heavy quarkonium mesons modified by medium effects at finite temperature and density by solving the radial Schrödinger equation with a complex heavy-quark potential derived from an improved Gauss law model. This potential incorporates medium screening through a temperature- and density-dependent Debye mass parameter, featuring a real part that...

24. Thermalization and Transport Phenomena in Oxygen-Oxygen Collisions at √(s_NN )=7 TeV: A Color String Percolation Model Approach

Ms Thresia Michael (Department of Physics, University Institute of Sciences, Chandigarh University, Gharuan, Mohali, Punjab)

04/09/2025, 17:00

Poster

The investigation of the QCD phase transition and the Quark-Gluon Plasma (QGP) formation in high-energy nuclear collisions continues to be a central focus in modern nuclear physics. While traditionally associated with heavy-ion collisions, recent studies suggest that QGP-like droplets may also emerge in high-multiplicity proton-proton (pp) events. Motivated by these findings, the present study...

82. Heavy quark relaxation time from the effective QCD potential

Mr Prasanta Murmu (Indian Institute of Technology Bhilai)

04/09/2025, 17:10

Poster

In this work, we investigate the scattering cross section for heavy quark using the Dual QCD potential within the framework of the Born approximation. The scattering cross section is presented as a function of momentum. This study is further extended to calculate the relaxation time and analyze its dependence on temperature.

31. Mass Spectra of Cascade Bottom–Charm Baryons ( $\Xi_{bc}$, $\Xi'_{bc}$ ) in a Relativistic Flux Tube Model

Mr V.G. Prajapati (Sardar Vallabhbhai National Institute Of Technology)

04/09/2025, 17:10

Poster

Using the relativistic flux tube model with spin effects, we present an investigation of the mass spectra of the $\Xi_{bc}$ and $\Xi'_{bc}$ baryons. This quark--diquark approach treats each baryon as a (bc) diquark bound to a light quark by a rotating string-like flux tube, incorporating spin dependent interactions. Our predicted masses for the ground-state $\Xi_{bc}$ and $\Xi'_{bc}$ align...

43. Numerical Relativistic Magnetohydrodynamics and Related study in Heavy Ion Collisions

Krishanu Sengupta (National Institute of Science Education and Research)

04/09/2025, 17:10

Poster

Relativistic heavy-ion collisions generate a deconfined state of nuclear matter known as the quark-gluon plasma (QGP), along with extremely strong magnetic fields (~10¹⁸–10¹⁹ Gauss) in non-central events. These fields can significantly modify the transport properties of the QGP, such as its conductivity and viscosity. In this work, we numerically investigate the QGP evolution using the...

30. Investigation of the Mass Spectra of Singly Charmed Pentaquarks

Hardik Rathod (Sardar Vallabhbhai National Institute of Technology)

04/09/2025, 17:20

Poster

In this study, we calculate the mass spectra of singly charmed pentaquark states using the hypercentral constituent quark model (HCQM). The pentaquark is treated as a bound system consisting of two diquarks and an antiquark, with their interactions described by a potential that includes both a linear confining term and a Coulomb term. To account for the fine structure of the mass spectra,...

59. Modelling transport properties of compressed baryonic matter

Anand Rai (IIT BHILAI)

04/09/2025, 17:20

Poster

We present a comparative study of key transport coefficients—electrical conductivity ($\sigma$), thermal conductivity ($\kappa$), shear viscosity ($\eta$), and the Lorenz number ($\kappa/\sigma T$) by using different models: Hadron Resonance Gas (HRG) model, the Nambu–Jona-Lasinio (NJL) model, and effective chiral model. By examining their dependence on temperature and net baryon density, our...

46. Probing Dissipative Dynamics of Hybrid Stars through r-mode Oscillations

KHUSHBU ZALA

04/09/2025, 17:20

Poster

We study the damping of r-mode oscillations in hybrid stars, focusing on bulk viscosity as the dominant dissipative mechanism. In the hybrid star the mixed phase emerges due to a first-order phase transition between hadronic and quark matter at high baryon densities, and is treated as a distinct region with its own transport properties. Bulk viscosity is computed by incorporating...
