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…
Path integral representation for stochastic jump processes with boundaries
Takashi Arai
We propose a formalism to analyze discrete stochastic processes with finite-state-level N. By using an (N+1)-dimensional representation of su(2) Lie algebra, we re-express the mast…
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…
