We include the $\eta_c$ meson into the $\eta$-$\eta'$-$G$ mixing
formalism constructed in our previous work, where $G$ represents the
pseudoscalar gluball. The mixing angles in this tetramixing
matrix are constrained by theoretical and experimental implications
from relevant hadronic processes. Especially, the angle between
$\eta_c$ and $G$ is found to be about $15^\circ$ from the...

A model relating radiative seesaw and minimal dark matter mass scales without beyond the standard model (SM) gauge symmetry (RνMDM) is constructed. In addition to the SM particles, the RνMDM contains, a Majorana fermion multiplet NR and scalar multiplet χ that transform respectively as (1, 5, 0) and (1, 6,−1/2) under the SM gauge group SU(3)C ×SU(2)L ×U(1)Y .This choice for representation of...

We evaluate the ultra high energy neutrino event rate from the lunar observation using the analytic expression of the effective aperture by Gayley et al.. We modify this formalism for strong attenuation and evaluate the background from cosmic ray interaction in the lunar regolith. We also make modifications to the effective aperture for the non-standard model neutrino interaction and calculate...

We study the variation of particle number in non-equilibirum enviroment. Using the scalar model with the particle number violating interactions, we study the time development of the particle number using the Closed Path Time (CPT) formalism. Two types of the particle number interactions are considered. One is the particle number violationg mass term and the other drives particle number...

We study the complementarity between quark and lepton mixing angles (QLC), the sum of an angle in quark mixing and the corresponding angle in lepton mixing is π/4. Experimentally in the standard PDG parametrization, two such relations exist approximately. These QLC relations are accidental which only manifest themselves in the PDG parametrization. We propose reparametrization invariant...
