Radiative decays of mesons in the NJL model [PDF]

, 2001
We revisit the theoretical predictions for anomalous radiative decays of pseudoscalar and vector mesons. Our analysis is performed in the framework of the Nambu-Jona-Lasinio model, introducing adequate parameters to account for the breakdown of chiral ...

Mesonic excitations and pi--pi scattering lengths at finite temperature in the two-flavor Polyakov--Nambu--Jona-Lasinio model

, 2009
The mesonic excitations and s-wave pi--pi scattering lengths at finite temperature are studied in the two-flavor Polyakov--Nambu--Jona-Lasinio (PNJL) model.

Oscillations of the static meson fields at finite baryon density [PDF]

, 1996
The spatial dependence of static meson correlation functions at finite baryon density is studied in the Nambu -- Jona - Lasinio model. In contrast to the finite temperature case, we find that the correlation functions at finite density are not screened ...

Thermoelectric transport coefficients of quark matter

European Physical Journal C: Particles and Fields, 2022
A thermal gradient and/or a chemical potential gradient in a conducting medium can lead to an electric field, an effect known as thermoelectric effect or Seebeck effect.

Parameter fitting in three-flavor Nambu–Jona-Lasinio model with various regularizations

Nuclear Physics B, 2016
We study the three-flavor Nambu–Jona-Lasinio model with various regularization procedures. We perform parameter fitting in each regularization and apply the obtained parameter sets to evaluate various physical quantities, several light meson masses ...

Can oscillating neutrino states be formulated universally?

European Physical Journal C: Particles and Fields, 2020
A standing problem in neutrino physics is the consistent and universal definition of oscillating neutrino states as coherent superpositions of massive neutrino states.

Majorana neutrino and the vacuum of Bogoliubov quasiparticle

Physics Letters B, 2018
The Lagrangian of the seesaw mechanism is C violating but the same Lagrangian when re-written in terms of Majorana neutrinos is manifestly C invariant.

Quark–meson coupling model based upon the Nambu–Jona Lasinio model

Physics Letters B, 2016
The NJL model for the octet baryons, using proper time regularisation to simulate some of the features of confinement, is solved self-consistently in nuclear matter.

Wigner solution of the quark gap equation

European Physical Journal C: Particles and Fields, 2018
Solutions and their evolutions of the quark gap equation are studied within the Nambu–Jona–Lasinio model, which is a basic issue for studying the QCD phase structure and locating the possible critical end point.

Structure Functions of the Nucleon in a Soliton Model

, 2019
We study nucleon structure functions in the soliton picture of the bosonized Nambu-Jona-Lasinio model. We focus on their vacuum contributions and examine whether they are outweighed by their valence quark counterparts.Comment: 4 pages, contribution to ...
