Electric polarizability of pions in semirelativistic quark model

Abstract

The generalized and static polarizabilities of charged pions, which are considered a relativistic sys tem of two pointlike spinor quarks with a linear interaction potential, are calculated. The relationship between static electricity and generalized polarizabilities of pions is studied in the context of this approach.

Thermophysical properties and mass spectra of meson systems via Nikiforov-Uvarov method

“…For example, Modarres et al studied the thermodynamic properties of quark-gluon plasma, as well as its phase diagram as a function of baryon density and temperature [34]. Furthermore, thermodynamic properties are investigated within the framework of chiral quark models and in molecular physics using both relativistic and non-relativistic models [35,36].…”

Solutions of Klein-Gordon equation for the modified central complex potential in the symmetries of noncommutative quantum mechanics

“…An adequate understanding of the quark behavior of two interacting quarks as a function of their relative positions is very pertinent in different fields of sub-atomic and elementary particles using various potential schemes. Recently, there has been a great interest in obtaining quark potential energy functions governing the interaction of twoquarks (mesons model) [1][2][3][4][5][6][7][8][9][10] . In particular, the complex potentials such as exponential type complex and non-Hermitian potentials, generalized Hulthén potential in complex quantum mechanicsand central complex potentials r b iar r V / ) (…”
