Advances in High Energy Physics, Volume 2016, Issue 1, 2016., 2016 Strange hadrons, especially multistrange hadrons, are good probes for the early partonic stage of heavy ion collisions due to their small hadronic cross sections. In this paper, I give a brief review on the elliptic flow measurements of strange and multistrange hadrons in relativistic heavy ion collisions at Relativistic Heavy Ion Collider (RHIC) and ...

How neutron stars constrain the nuclear equation of state
EPJ Web of Conferences, 2014 Recent neutron star observations set new constraints for the equation of state of baryonic matter. A chiral effective field theory approach is used for the description of neutron-dominated nuclear matter present in the outer core of neutron stars ...

A proposal of a renormalizable Nambu–Jona-Lasinio model
European Physical Journal C: Particles and Fields, 2018 A local and gauge invariant gauge field model including Nambu–Jona-Lasinio (NJL) and QCD Lagrangian terms in its action is introduced. Surprisingly, it becomes power counting renormalizable. This occurs thanks to the presence of action terms which modify

Effective models of two-flavor QCD: from small towards large $m_q$
, 2009 We study effective models of chiral fields and Polyakov loop expected to describe the dynamics responsible for the phase structure of two-flavor QCD.

Interacting Dark Matter and q‐Deformed Dark Energy Nonminimally Coupled to Gravity
Advances in High Energy Physics, Volume 2016, Issue 1, 2016., 2016 In this paper, we propose a new approach to study the dark sector of the universe by considering the dark energy as an emerging q‐deformed bosonic scalar field which is not only interacting with the dark matter, but also nonminimally coupled to gravity, in the framework of standard Einsteinian gravity.

QCD phase diagram in a finite volume in the PNJL model
Open Physics, 2022 In this work, we study the quantum chromodynamics phase diagram at finite temperature and non-zero chemical potential in the framework of the SU(2) flavor of the Polyakov–Nambu – Jona–Lasinio model (PNJL).

Calculations of ${\cal O}(p^6)$ Resonance Coupling Constants in the Scalar Sector of the ENJL Model
, 2007 We derive the scalar resonance coupling constants of resonance chiral theory from the Extended Nambu Jona-Lasinio model by using heat-kernel expansion.Comment: 7 ...

, 1996 A short review of some of the most relevant contributions to non-perturbative QED is done. Since a Gaussian behaviour of QED \`a la $\lambda\phi^4$ has been ruled out by the numerical data, I analyse the other two most reliable scenarios, i.e. triviality

On SU(3) Effective Models and Chiral Phase Transition
Advances in High Energy Physics, Volume 2015, Issue 1, 2015., 2015 Sensitivity of Polyakov Nambu‐Jona‐Lasinio (PNJL) model and Polyakov linear sigma‐model (PLSM) has been utilized in studying QCD phase‐diagram. From quasi‐particle model (QPM) a gluonic sector is integrated into LSM. The hadron resonance gas (HRG) model is used in calculating the thermal and dense dependence of quark‐antiquark condensate.

Quantum simulation of chiral phase transitions
Journal of High Energy Physics, 2022 The Nambu–Jona-Lasinio (NJL) model has been widely studied for investigating the chiral phase structure of strongly interacting matter. The study of the thermodynamics of field theories within the framework of Lattice Field Theory is limited by the sign ...
