Temperature Dependence of the Masses of Various Meson States: A Comparative Study in SU(3) and SU(4) extended Linear-Sigma Model
Alexandra Friesen, Yu. Kalinovsky, Saleh O. Allehabi +3
In the extended Linear-Sigma Model (eLSM), the chiral phase structure of meson states, including pseudoscalars (), scalars (), vectors ($J^{pc}=1^{--}…

Mesons in nonlocal model with four-dimensional separable kernel
A. Friesen, Yu. Kalinovsky, A. Khmelev
In this work we study the meson properties in the framework of an effective quark model. We start from the Bethe-Salpeter equation choosing the interaction kernel in nonlocal form…

Derivation of Meson Masses in SU(3) and SU(4) Extended Linear-Sigma Model at Finite Temperature
Abdel Nasser Tawfik, Azar I. Ahmadov, Alexandra Friesen +3
The present study focuses on the mesonic potential contributions to the Lagrangian of the extended linear-sigma model (eLSM) for scalar and pseudoscalar meson fields across various…
