Bayesian analysis of the properties of hybrid stars with the Nambu–Jona-Lasinio model [PDF]
The possible presence of deconfined matter in the cores of massive neutron stars is the subject of a large debate. In this context, it is important to set limits on the size and characteristics of a hypothetical quark core compatible with the present ...

Anisotropic Behavior of S‐Wave and P‐Wave States of Heavy Quarkonia at Finite Magnetic Field
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
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
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
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

Kaon generalized parton distributions and light-front wave functions in the Nambu–Jona-Lasinio model
Kaon generalized parton distributions (GPDs) and the leading Fock state light-front wave functions are investigated in the framework of Nambu–Jona-Lasinio model with proper time regularization.

Non-Hermitian extension of the Nambu–Jona-Lasinio model in 3+1 and 1+1 dimensions [PDF]
This paper presents a non-Hermitian PT-symmetric extension of the Nambu--Jona-Lasinio (NJL) model of quantum chromodynamics in 3+1 and 1+1 dimensions.

Spontaneous electromagnetic superconductivity of vacuum in a strong magnetic field: evidence from the Nambu-Jona-Lasinio model. [PDF]
Using an extended Nambu-Jona-Lasinio model as a low-energy effective model of QCD, we show that the vacuum in a strong external magnetic field (stronger than 10(16) T) experiences a spontaneous phase transition to an electromagnetically superconducting

Two-current correlations in the pion in the Nambu and Jona-Lasinio model
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 ...

Thermo-magnetic effects in quark matter: Nambu-Jona-Lasinio model constrained by lattice QCD [PDF]
.The phenomenon of inverse magnetic catalysis of chiral symmetry in QCD predicted by lattice simulations can be reproduced within the Nambu-Jona-Lasinio model if the coupling G of the model decreases with the strength B of the magnetic field and ...
