Compositeness of baryonic resonances: Applications to the Delta(1232), N(1535), and N(1650) resonances
Takayasu Sekihara, Takashi Arai, Junko Yamagata-Sekihara +1
We present a formulation of the compositeness for baryonic resonances in order to discuss the meson-baryon molecular structure inside the resonances. For this purpose, we derive a…
Compositeness of the Delta(1232) resonance in pi N scattering
Takayasu Sekihara, Takashi Arai, Junko Yamagata-Sekihara +1
We evaluate the compositeness of the resonance so as to clarify the internal structure of in terms of the component. Here the compositeness is defined…
Euler-Heisenberg-Weiss action for QCD+QED
Sho Ozaki, Takashi Arai, Koichi Hattori +1
We derive an analytic expression for one-loop effective action of QCD+QED at zero and finite temperatures by using the Schwinger's proper time method. The result is a nonlinear eff…
