Manifestation of a nontrivial vacuum in discrete light cone quantization
Takanori Sugihara, Masa-aki Taniguchi
We study a (1+1)-dimensional model with a light-cone zero mode and constant external source to describe spontaneous symmetry breaking. In the broken phase, we find degenerat…
Dynamics of the Light-Cone Zero Modes: Theta Vacuum of the Massive Schwinger Model
Koji Harada, Atsushi Okazaki, Masa-aki Taniguchi
The massive Schwinger model is quantized on the light cone with great care on the bosonic zero modes by putting the system in a finite (light-cone) spatial box. The zero mode of $A…
Mesons in the massive Schwinger model on the light-cone
koji Harada, Atsushi Okazaki, Masa-aki Taniguchi
We investigate mesons in the bosonized massive Schwinger model in the light-front Tamm-Dancoff approximation in the strong coupling region. We confirm that the three-meson bound st…
Six-body Light-Front Tamm-Dancoff approximation and wave functions for the massive Schwinger model
Koji Harada, Atsusi Okazaki, Masa-aki Taniguchi
The spectrum of the massive Schwinger model in the strong coupling region is obtained by using the light-front Tamm-Dancoff (LFTD) approximation up to including six-body states. We…
The massive Schwinger model with on the light cone
Koji Harada, Takanori Sugihara, Masa-aki Taniguchi +1
The massive Schwinger model with two flavors is studied in the strong coupling region by using light-front Tamm-Dancoff approximation. The mass spectrum of the lightest particles i…
