Spin polarizations under a pseudovector interaction between quarks with the Kobayashi-Maskawa-'t Hooft term in high density quark matter

M. Morimoto, Y. Tsue, J. da Providencia +2

A possibility of a quark spin polarization originated from a pseudovector condensate is investigated in the three-flavor Nambu-Jona-Lasinio model with the Kobayashi-Maskawa-'t Hoof…

Exploration of the phase diagram and the thermodynamic properties of QCD at finite temperature and chemical potential with the PNJL effective model

M. Motta, W. M. Alberico, A. Beraudo +2

The QCD transition from a hadronic to a quark-gluon plasma phase is a cross-over at vanishing/small baryo-chemical potential, while at higher chemical potentials it is argued that…

Aspects of isentropic trajectories in chiral effective models

Rainer Stiele, Wanda Maria Alberico, Andrea Beraudo +4

The evolution of the fireball in heavy ion collisions is an isentropic process, meaning that it follows a trajectory of constant entropy per baryon in the phase diagram of the stro…

Second look to the Polyakov Loop Nambu-Jona-Lasinio model at finite baryonic density

O. Ivanytskyi, M. Ángeles Pérez-García, V. Sagun +1

We revisit the Polyakov Loop coupled Nambu-Jona-Lasinio model that maintains the Polyakov loop dynamics in the limit of zero temperature. This is of interest for astrophysical appl…

The Role of the $t t ˉ h$ Rest Frame in Direct Top-Quark Yukawa Coupling Measurements

Andrea Ferroglia, Miguel C. N. Fiolhais, Emanuel Gouveia +1

This paper studies new possibilities to directly measure a hypothetical $C P$ -odd (pseudoscalar) component in the top-quark Yukawa coupling. In particular, the role of the $t{\bar t…

Towards a reliable effective field theory of inflation

Mar Bastero-Gil, Arjun Berera, Rudnei O. Ramos +1

We present the first quantum field theory model of inflation that is renormalizable in the matter sector, with a super-Hubble inflaton mass and sub-Planckian field excursions, whic…

Top condensation model: a step towards the correct prediction of the Higgs mass

A. A. Osipov, B. Hiller, A. H. Blin +3

A realization of the composite Higgs scenario in the context of the effective model with the $S U (2)_{L} \times U (1)_{R}$ symmetric four-Fermi interactions proposed by Miransky, Tanabash…

Phase Diagram, Scalar-Pseudoscalar Meson Behavior and Restoration of Symmetries in (2+1) Polyakov-Nambu-Jona-Lasinio Model

Pedro Costa, Renan Câmara Pereira

We explore the phase diagram and the modification of mesonic observables in a hot and dense medium using the (2+1) Polyakov-Nambu-Jona-Lasinio model. We present the phase diagram i…

Quark and Polyakov-loop correlations in effective models at zero and non-vanishing density

Hubert Hansen, Rainer Stiele, Pedro Costa

The aim of this work is to shed light on some lesser known aspects of Polyakov-loop--extended chiral models (namely the Polyakov-loop extended Nambu--Jona-Lasinio and Quark-Meson m…

Constraining dimension-six nonminimal Lorentz-violating electron-nucleon interactions with EDM physics

Jonas B. Araujo, A. H. Blin, Marcos Sampaio +1

The electric dipole moment (EDM) of an atom could arise also from $P$ -odd and $T$ -odd electron-nucleon couplings. In this work we investigate a general class of dimension- $6$ elect…
