Stable Neutral Fermi Ball
K. Ogure, T. Yoshida, J. Arafune
Fermi Ball is a kind of nontopological soliton with fermions trapped in its domain wall, and is suggested to arises from the spontaneous symmetry breaking of the approximate …
Stability and experimental flux bound of Fermi Ball
Kenzo Ogure, Jiro Arafune, Takufumi Yoshida
We investigate the stability of an Fermi ball(F-ball) within the next-to-leading order approximation in the thin wall expansion. We find out that an F-ball is unstable in case that…
Experimental Bounds on Masses and Fluxes of Nontopological Solitons
J. Arafune, T. Yoshida, S. Nakamura +1
We have re-analyzed the results of various experiments which were not originally interested as searches for the Q-ball or the Fermi-ball. Based on these analyses, in addition to th…
Finiteness of Multi-body Neutrino Exchange Potential Energy in Neutron Stars
Jiro Arafune, Yukihiro Mimura
The multi-body neutrino potential energy is analytically estimated for a spherical neutron star with a vector potential model for neutrinos. We show that the self-energy and the ne…
Non-perturbative Evaluation of the Effective Potential of Theory at Finite Temperature under the Super-Daisy Approximation
Jiro Arafune, Kenzo Ogure, Joe Sato
We calculate the effective potential of the scalar theory at finite temperature under the super-daisy approximation, after expressing its derivative with respect to mass square in…
CP Violation and Matter Effect in Long Baseline Neutrino Oscillation Experiments
Jiro Arafune, Masafumi Koike, Joe Sato
We show simple methods how to separate pure CP violating effect from matter effect in long baseline neutrino oscillation experiments with three generations of neutrinos. We give co…
