We consider the prescription dependence of the Higgs effective potential
under the presence of general nonminimal couplings. We evaluate the fermion
loop correction to the effective action in a simplified Higgs-Yukawa model
whose path integral mea...

We investigate the Higgs potential beyond the Planck scale in the superstring theory, under the assumption that the supersymmetry is broken at the string scale. We identify the Higgs field as a massless state of the string, which is indicated by t...

The observed Higgs mass MH=125.9±0.4GeV leads to the criticality of the standard model, that is, the Higgs potential becomes flat around the scale 10[17-18]GeV for the top mass 171.3 GeV. Earlier we proposed a Higgs inflation scenario in which thi...

We study implications of generalized non-zero Dirichlet boundary condition
along with the ordinary Neumann one on a bulk scalar in the Randall-Sundrum
warped compactification. First we show profiles of vacuum expectation value of
the scalar under ...
We clarify and study our previous observation that, under a compactification
with boundaries or orbifolding, vacuum expectation value of a bulk scalar field
can have different extra-dimensional wave-function profile from that of the
lowest Kaluza-...
We propose a simple five-dimensional extension of the Standard Model (SM)
without any Higgs potential nor any extra fields. A Higgs doublet lives in the
bulk of a flat line segment and its boundary condition is Dirichlet at the ends
of the line, w...
