The study of hadron by means of QCD is still unable to answer the unsolved puzzle; the hadron structures, especially those of heavy mesons. Hence, a comprehensive investigation of the 1S, 2S, and 3S states of heavy pseudoscalar (P) and vector (V) mesons for charmonia ($c\bar{c}$), bottomia ($b\bar{b}$), and charm-bottom ($c\bar{b}$) is strongly required. By employing the light-front quark...

We have investigated the transverse parton distribution of the proton through the momentum‐transfer squared ($t$) distribution data of the differential cross section for coherent $J/\psi$ production at HERA. Based on a Gaussian–hotspot model motivated by a three valence quark picture of a proton, we introduce three independent geometric degrees of freedom: (1) the overall impact–parameter size...

The internal structure of the pion is investigated using generalized parton distribution (GPD) within the framework of the covariant Nambu–Jona-Lasinio (NJL) model. As an effective chiral symmetry-based theory of QCD, the NJL model provides valuable insight into non-perturbative aspects of pion structure. In the NJL model, to omit the divergence in the quark propagators, we apply a proper-time...

Starting from the relativistic manner, in this work, we construct the non-derivative four-point interactions for Octet and Decuplet baryons in the Chiral Effective Field Theory (ChEFT). The non-relativistic expansion of the baryon fields has been considered up to the Next-Leading Order (NLO) of the three-momentum. Using the 1/$N_c$ operator product expansion up to 1/$N_c^2$, we can reduce the...

Nuclear deformity has been known to introduce fluctuations in the initial geometry and multiplicity in heavy-ion collisions. As the centrality bin is often calculated based on the multiplicity, this fluctuation is propagated as a larger correlation uncertainty between collision parameters and experiment observables. The aim of this study is to establish a framework to construct the probability...

Neutron stars exhibit sudden changes of its rotational velocity, known as "pulsar glitches". It has been believed that glitches are mainly caused by superfluid neutron vortices in the inner crust of neutron stars. However, importance of contributions of the outer core has been recently discussed, and further microscopic investigations of quantum vortices and fluxtubes in the outer core of...

Recent observations of neutron stars indicate that there must be corrections to Einstein's theory of gravity. This research aims to study gravitational modifications in neutron stars. The GUP (Generalized Uncertainty Principle) effect is incorporated into the RG (Rainbow Gravity) metric in the slowly rotating case. GUP itself will affect the nuclear properties in neutron star matter, causes...

In this work, we investigate an effective Lagrangian that describes the interactions between $D$ mesons, charmed baryons ($Y_c$), and nucleons within the framework of Heavy-Quark Spin Symmetry (HQSS). Using the super-multiplet formalism, we systematically construct the three-point interaction terms. As a result, by considering the minimal sets of the effective Lagrangian in the HQSS...

We introduce a geometric framework for non-unitary quantum processes, in line with the unitary SU(N) geometry. We propose a Finslerian metric for our goal, which modifies the original unitary geometry by applying the restrictions from Lindblad Master Equations from the perspective of Pontryagin's Maximum Principle (PMP). We illustrate the results of the Finslerian metrics for depolarising and...

We study the internal structure of exotic hadrons, especially focusing on the relation between the compositeness and physical observables [1, 2]. Defined as the probability of finding hadronic molecular components in the wave function, compositeness serves as a quantitative measure of the internal structure of exotic hadrons. We utilize the coupled-channel potential model incorporating both...

In this work, we aim to calculate the diquark mass together with the quark-diquark potential in which we apply an extended HAL QCD potential method to a baryonic system made up from a static quark and a diquark. We consider various types of diquarks
(eg: scalar $0^{+}$ diquark, axial-vector $1^{+}$ diquark etc) to examine their mass differences.Numerical calculations are...

In this study, we investigate the elastic scattering of proton-proton ($pp$) and proton-antiproton ($p\bar{p}$) systems in the Regge limit ($s>>|t|$), focusing on the contributions of spin-2 pomeron and spin-3 odderon exchanges to the scattering amplitude. Starting from effective Lagrangians describing these exchanges, we derive the corresponding amplitudes within the standard perturbative...

We investigate two-pion emission decays of singly charmed and bottom baryons, focusing on $\Lambda_Q^*(1P)$ and $\Xi_Q^*(1P)$ states with $J^P = 1/2^−$ and $3/2^−$, which belong to the flavor triplet $\bar{3}_F$. Our study includes both sequential decays through intermediate states in the flavor sextet $6_F$ and direct three-body decay, with coupling constants estimated using the chiral-quark...

Currently, one of the most important and difficult areas of research in nuclear structure is the production of superheavy elements. All superheavy elements discovered so far are not stable against the two dominant decay modes, namely alpha decay and spontaneous fission. The decay modes and other essential properties of these nuclei have not been fully investigated experimentally due to their...

Quantum computers have also shown potential for efficient Hamiltonian simulation where computational resources scaling polynomially with system size. For instance, the Variational Quantum Eigensolver (VQE) has been adapted to evaluate ground state energy of nuclei [1] and the hardware specification needed [2], and to solve Bardeen-Cooper-Schrieffer (BCS) Hamiltonian [3]. In this project, we...

The encoded nuclear structures related to flow fluctuations can be investigated at a fixed impact parameter in ultra-relativistic ion collisions through factorization breaking. This phenomenon is explored by analyzing momentum-dependent correlations among flow harmonics across distinct kinematic bins, specifically regarding transverse momentum ($p_T$) or pseudorapidity ($\eta$). The influence...
