Yoonbai Kim, Sho Tsujimaru, Koichi Yamawaki
Spontaneous breakdown of the continuous symmetry is studied in the framework of discretized light-front quantization. We consider linear sigma model in 3+1 dimensions and show that…

Can the Nambu-Goldstone Boson Live on the Light-Front?
Yoonbai Kim, Sho Tsujimaru, Koichi Yamawaki
We show that the Nambu-Goldstone(NG) boson restricted on the light-front(LF) can only exist if we regularize the theory by introducing the explicit breaking NG-boson mass . Th…
