Effective linear meson model

, 1996
The effective action of the linear meson model generates the mesonic n-point functions with all quantum effects included. Based on chiral symmetry and a systematic quark mass expansion we derive relations between meson masses and decay constants.

Polarizability of pseudoscalar mesons from the lattice calculations

EPJ Web of Conferences, 2016
We explore the energy dependence of neutral and charge pions of the background constant abelian magnetic field in SU(3) lattice gauge theory without dynamical quarks. The energy of neutral pseudoscalar meson diminishes with the field, while the energy of

Derivation of Meson Masses in SU(3) and SU(4) Extended Linear Sigma Model at Finite Temperature

Particles
The present study focused on the mesonic potential contributions to the Lagrangian of the extended linear sigma model (eLSM) for scalar and pseudoscalar meson fields across various quark flavors.
