There is renewed attention to whether we can observe the decoherence effect
in neutrino oscillation due to the separation of wave packets with different
masses in near-future experiments. As a contribution to this endeavor, we
extend the existing ...
We define a set of fully Lorentz-invariant wave packets and show that it
spans the corresponding one-particle Hilbert subspace, and hence the whole Fock
space as well, with a manifestly Lorentz-invariant completeness relation
(resolution of identi...

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 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 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...
