Abstract

We discuss the possibility of producing the bound states of the {eta}'(958) meson in nuclei theoretically using the the Nambu-Jona-Lasinio (NJL) model. We calculate the formation cross section of the {eta}' bound states with the Green function method for the ({gamma},p) reaction and discuss the experimental feasibility at photon facilities such as SPring-8. We conclude that we can expect to observe resonance peaks in ({gamma},p) spectra for the formation of {eta}' bound states and we can deduce new information on {eta}' properties at finite density. These observations are believed to be essential to know the possible mass shift of {eta}' and deduce new information on the effective restoration of the chiral UA(1) anomaly at finite density.

{eta}- and {eta}{sup '}-mesic nuclei and U{sub A}(1) anomaly at finite density

Journal Article Nagahiro, Hideko; Takizawa, Makoto; Hirenzaki, Satoru - Physical Review. C, Nuclear Physics

We discuss theoretically the possibility of observing the bound states of the {eta} and {eta}{sup '}(958) mesons in nuclei. We apply the NJL model to study the {eta} and {eta}{sup '} meson properties at finite density and calculate the formation cross sections of the {eta} and {eta}{sup '} bound states with the Green function method for ({gamma},p) reaction. We also discuss the experimental feasibility at photon facilities like SPring-8. The contributions due to the {omega} meson production are also included to obtain the realistic ({gamma},p) spectra. We conclude that we can expect to observe resonance peaks in ({gamma},p) spectra formore »« less

Anomalous decay of pion and {eta} at finite temperature

Journal Article Costa, P; Ruivo, M; Kalinovsky, Yu - Physical Review. C, Nuclear Physics

We study the anomalous decays {pi}{sup 0},{eta}{yields}{gamma}{gamma} in the framework of the three-flavor Nambu-Jona-Lasinio (NJL) model at finite temperature. The similarities and differences between these results and those obtained at zero temperature and finite density are discussed. In both cases the lifetimes of these mesons decrease significantly at the critical point, although this might not be sufficient to observe enhancement of these decays in heavy-ion collisions.

Hot QCD at finite isospin density: Confronting the SU(3) Nambu–Jona-Lasinio model with recent lattice data

Journal Article Lopes, Bruno; Avancini, Sidney; Bandyopadhyay, Aritra; ... - Physical Review D

Extending our recently published SU(2) results for zero temperature, we now compute the QCD equation of state for finite isospin density within the three-flavor Nambu–Jona-Lasinio (NJL) model in the mean field approximation, motivated by the recently obtained lattice QCD results for both zero and finite temperatures. Like our previous study, here also we have considered both the commonly used traditional cutoff regularization scheme and the medium separation scheme. Our results are compared with recent high-precision lattice simulations as well as previously obtained results in two-flavor Nambu–Jona-Lasinio model. The agreement between the lattice results and the predictions from three-flavor NJL modelmore »« less

Light front NJL model at finite temperature

Journal Article Strauss, S; Beyer, M; Mattiello, S - AIP Conference Proceedings

We investigate the properties of qq and qq-bar states in hot and dense quark matter in the framework of light-front finite temperature field theory. Presently we consider the Nambu Jona-Lasinio (NJL) model and derive the gap equation at finite temperature and density. We study pionic and scalar diquark dynamics in quark matter and compute the two-body masses and the Mott dissociation using a t-matrix approach. For the scalar diquark we determine the critical temperature of color superconductivity.
