Comment on "Scrutinizing pion-pion scattering in light of recent lattice phase shifts"
Eef van Beveren, George Rupp
In a recent paper by Xiu-Li Gao, Zhi-Hui Guo, Zhiguang Xiao, and Zhi-Yong Zhou, Phys. Rev. D 105, 094002 (2022), here referred to as I, -wave scattering phase shifts obtain…
Understanding the and masses as well as their widths
Eef van Beveren, George Rupp
The low and approximately equal masses of the scalar mesons and , as well as their relatively small decay widths, are impossible to understand in terms of stan…
Warm Inflation, Neutrinos and Dark matter: a minimal extension of the Standard Model
Miguel Levy, João G. Rosa, Luis B. Ventura
We show that warm inflation can be realized within a minimal extension of the Standard Model with three right-handed neutrinos, three complex scalars and a gauged lepton/B-L U(1) s…
Modern meson spectroscopy: the fundamental role of unitarity
Eef van Beveren, George Rupp
The importance of -matrix unitarity in realistic meson spectroscopy is reviewed, both its historical development and more recent applications. First the effects of imposing -…
Two-loop renormalisation of gauge theories in Implicit Regularisation and connections to dimensional methods
A. Cherchiglia, D. C. Arias-Perdomo, A. R. Vieira +2
We compute the two-loop -function of scalar and spinorial quantum electrodynamics as well as pure Yang-Mills and quantum chromodynamics using the background field method in a fu…
Classical excluded volumes of loosely bound light (anti)nuclei and their chemical freeze-out in heavy ion collisions
B. E. Grinyuk, K. A. Bugaev, V. V. Sagun +12
From the analysis of light (anti)nuclei multiplicities that were measured recently by the ALICE collaboration in Pb+Pb collisions at the center-of-mass collision energy $\sqrt{s_{N…
One-meson-loop NJL model: Effect of collective and noncollective excitations on the quark condensate at finite temperature
Renan Câmara Pereira, Pedro Costa
We explore the effect of including quantum fluctuations in the two flavor NambuJona-Lasinio model at finite temperature. This is accomplished, in a symmetry preserving way, by i…
Non-zero tensor condensates in cold quark matter within the three-flavor Nambu-Jona-Lasinio model with the Kobayashi-Maskawa-'t Hooft interaction
A. Kagawa, M. Morimoto, Y. Tsue +3
The possible formation of tensor condensates originated from a tensor-type interaction between quarks is investigated in the three-flavor Nambu-Jona-Lasinio model including the Kob…
Functional renormalization group study of the critical region of the quark-meson model with vector interactions
Renan Câmara Pereira, Rainer Stiele, Pedro Costa
The critical region of the two flavour quark-meson model with vector interactions is explored using the Functional Renormalization Group technique, a non-perturbative method that t…
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…
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…

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 -odd and -odd electron-nucleon couplings. In this work we investigate a general class of dimension- elect…
