Current status and muon explanation of lepton portal dark matter
Junichiro Kawamura, Shohei Okawa, Yuji Omura
In this paper, we summarize phenomenology in lepton portal dark matter (DM) models, where DM couples to leptons and extra leptons/sleptons. There are several possible setups: compl…
Complete Vector-like Fourth Family with : A Global Analysis
Junichiro Kawamura, Stuart Raby, Andreas Trautner
In this paper we present an in-depth analysis of a recently proposed Standard Model extension with a complete fourth generation of quarks and leptons, which are vector-like with re…
A low-scale flavon model with a symmetry
Tetsutaro Higaki, Junichiro Kawamura
We propose a model that explains the fermion mass hierarchy by the Froggatt-Nielsen mechanism with a discrete symmetry. As a concrete model, we study a supersymmetric model…
Complete Vector-like Fourth Family and new for Muon Anomalies
Junichiro Kawamura, Stuart Raby, Andreas Trautner
We consider the Standard Model (SM) with the addition of a gauge symmetry and a complete fourth family of quarks and leptons which are vector-like with respe…
WIMP dark matter in the parity solution to the strong CP problem
Junichiro Kawamura, Shohei Okawa, Yuji Omura +1
We extend the Standard Model (SM) with parity symmetry, motivated by the strong CP problem and dark matter. In our model, parity symmetry is conserved at high energy by introducing…
Analysis of the TeV-scale mirage mediation with heavy superparticles
Junichiro Kawamura, Yuji Omura
We discuss effective models derived from a supersymmetric model whose mediation mechanism of supersymmetry (SUSY) breaking is namely mirage mediation. In this model, light higgsino…
