Nambu-Jona-Lasinio Model Coupled to Constant Electromagnetic Fields in D-Dimension
M. Ishi-i, T. Kashiwa, N. Tanimura
Critical dynamics of the Nambu-Jona-Lasinio model, coupled to a constant electromagnetic field in D=2, 3, and 4, is reconsidered from a viewpoint of infrared behavior and vacuum in…
A construction of N=2 and centerless N=4 superconformal fields via affine superalgebras
Minoru Wakimoto
In this note we give a new construction of the N=2 superconformal algebra using currents of the affine superalgebra and free bosonic fields, and also the N=4 supe…
Variational Mass Perturbation Theory for Light-Front Bound-State Equations
Koji Harada, Thomas Heinzl, Christian Stern
We investigate the mesonic light-front bound-state equations of the 't Hooft and Schwinger model in the two-particle, i.e. valence sector, for small fermion mass. We perform a high…
Critical Couplings in the Nambu--Jona-Lasinio Model with the Constant Electromagnetic Fields
M. Ishi-i, T. Kashiwa, N. Tanimura
A detailed analysis is performed for the Nambu--Jona-Lasinio model coupled with constant (external) magnetic and/or electric fields in two, three, and four dimensions. The infrared…
