Proton Decay and Axion Dark Matter in SO(10) Grand Unification via Minimal Left-Right Symmetry
Yuta Hamada, Masahiro Ibe, Yu Muramatsu +2
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 mi…
SUSY threshold corrections to quark and lepton mixing inspired by GUT models
Yu Muramatsu, Yoshihiro Shigekami
In the standard model (SM), the Cabibbo-Kobayashi-Maskawa (CKM) matrix is the only origin of flavor violations (FVs). On the other hand, in general, there are a lot of sources of t…
flavor symmetric model in SUSY SU(5) GUT
Yu Muramatsu, Hideaki Okane, Yusuke Shimizu +1
We propose a model with flavor symmetry for leptons and quarks in the framework of supersymmetric SU(5) grand unified theory (GUT). The running masses of quarks and charged l…
R-parity violating solutions to the anomaly and their GUT-scale unifications
Quan-Yi Hu, Xin-Qiang Li, Yu Muramatsu +1
Recently, several -physics experiments report interesting anomalies in the semi-leptonic decays of -mesons, such as the excess in the measurements. These ano…
Flavor physics in the multi-Higgs doublet models induced by the left-right symmetry
Syuhei Iguro, Yu Muramatsu, Yuji Omura +1
In this paper, we discuss the multi-Higgs doublet models, that could be effectively induced by the extended Standard Model (SM). In particular, we focus on the phenomenology in the…
Light flavon signals at electron - photon colliders
Yu Muramatsu, Takaaki Nomura, Yusuke Shimizu +1
Flavor symmetries are useful to realize fermion flavor structures in the standard model. In particular, discrete symmetry is used to realize lepton flavor structures, and som…
