Effective Potential for Theory at Finite Temperature in and
T. Hattori, M. Hayashi, T. Inagaki +1
We calculate the explicit expression of the effective potential in a theory at finite temperature in a static universe for arbitrary spacetime dimensions (2\leq D < 5). To s…
Complementarity between Gauge-Boson Compositeness and Asymptotic Freedom -- with scalar matter
Keiichi Akama, Takashi Hattori
We derive and solve the compositeness condition for the SU(N_c) gauge boson coupling with N_s scalar fields at the next-to-leading order in 1/N_s and the leading order in ln(Λ^2) (…
Probabilistic Naturalness Measure for Dipole Moments due to New Physics
Keiichi Akama, Takashi Hattori, Kazuo Katsuura
We introduce a probabilistic measure of naturalness (naturalness level) to fix naturalness bounds quantitatively. It is applied to the anomalous magnetic moments and the electric d…
Compositeness of gauge boson and asymptotic freedom in non-abelian gauge theory
Takashi Hattori
In order to investigate the composite gauge field, we consider the compositeness condition (i.e. renormalization constant ) in the general non-abelian gauge field theory. We…
