In a transition amplitude of wave-packets, e.g., that of the decay process, there are in and out time boundaries for the
initial and final configurations, respectively, when the
transition occurs in a finite tim...
We compute an -channel scalar scattering in the Gaussian wave-packet formalism at the
tree-level. We find that wave-packet effects, including shifts of the pole and
width of the propagator of , persist...

Gravity can be regarded as a consequence of local Lorentz (LL) symmetry,
which is essential in defining a spinor field in curved spacetime. The
gravitational action may admit a zero-field limit of the metric and vierbein at
a certain ultraviolet c...

We study the proton lifetime in the Grand Unified Theory (GUT),
which has the left-right (LR) symmetric gauge theory below the GUT scale. In
particular, we focus on the minimal model without the bi-doublet Higgs field in
the LR symmetric ...

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...
