Anisotropic Behavior of S‐Wave and P‐Wave States of Heavy Quarkonia at Finite Magnetic Field
Advances in High Energy Physics, Volume 2023, Issue 1, 2023., 2023 We studied the effect of momentum space anisotropy on heavy quarkonium states using an extended magnetized effective fugacity quasiparticle model (EQPM). Both the real and imaginary part of the potential has been modified through the dielectric function by including the anisotropic parameter ξ.

From cosmic matter to the laboratory
Astronomische Nachrichten, Volume 342, Issue 5, Page 808-818, June 2021., 2021 Abstract The recent discovery of binary neutron star mergers has opened a new and exciting venue of research into hot and dense strongly interacting matter. For the first time, this elusive state of matter, described by the theory of quantum chromo dynamics, can be studied in two very different environments.

String (Gravi)photons, “Dark Brane Photons”, Holography and the Hypercharge Portal
Fortschritte der Physik, Volume 69, Issue 6, June 2021., 2021 Abstract The mixing of graviphotons and dark brane photons to the Standard Model hypercharge is analyzed in full generality, in weakly‐coupled string theory. Both the direct mixing as well as effective terms that provide mixing after inclusion of SM corrections are estimated to lowest order.

An Effective Model for Glueballs and Dual Superconductivity at Finite Temperature
Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021 The glueballs lead to gluon and QCD monopole condensations as by‐products of color confinement. A color dielectric function G(∣ϕ∣) coupled with a Abelian gauge field is properly defined to mediate the glueball interactions at confining regime after spontaneous symmetry breaking (SSB) of the gauge symmetry. The particles are expected to form through the

Two-current correlations in the pion in the Nambu and Jona-Lasinio model
European Physical Journal C: Particles and Fields, 2020 We present an analysis of two-current correlations for the pion in the Nambu–Jona-Lasinio model, with Pauli–Villars regularization. We provide explicit expressions in momentum space for two-current correlations corresponding to the zeroth component of ...

QCD critical end point and baryon number fluctuation
He jishu, 2023 One of the main goals of relativistic heavy-ion collision (HIC) is to search for the critical end point (CEP) of quantum chromodynamics (QCD), and distribution of the net-proton number from experimental measurements shows non-monotonic behavior, which ...

Meson production in e+e- annihilation and tau lepton decays within extended NJL model [PDF]
EPJ Web of Conferences, 2019 The Nambu–Jona-Lasinio model is applied to describe processes of electron-positron annihilation into mesons at center-of-mass energies below 2GeV and hadronic decays of tau leptons. Contributions of intermediate scalar, vector, and axial-vector mesons in

Advances in High Energy Physics, Volume 2020, Issue 1, 2020., 2020 We study the strongly interacting matter phase diagram on the T − μ plane through the two flavor Polyakov extended NJL model. We compare the phase diagrams obtained from three different effective potentials, focusing on the behavior of the width of the crossover region and the critical end point for each case.

Chiral symmetry restoration with three chiral partners
SciPost Physics Proceedings, 2022 I discuss the masses of chiral partners in the context of chiral symmetry restoration at finite temperature. Using the Nambu–Jona-Lasinio model I first remind the usual situation where two mesons of opposed parity become degenerate above the chiral ...

Analysis of ρ condensation in a Nambu-Jona-Lasinio model
EPJ Web of Conferences, 2014 A non-local Nambu-Jona-Lasinio model can be derived from QCD in the lowenergy limit. In this way, it is possible to fix all the free parameters of the model with physical ones. We used this approach to derive a local limit to the Nambu-Jona-Lasinio model,
