Thermal Leptogenesis in $S O (10) \times U (1)_{A}$ SUSY GUT

Nobuhiro Maekawa, Kei Shibata, Masato Yamanaka

We investigate thermal leptogenesis within a supersymmetric grand unified theory (SUSY GUT) based on the $S O (10) \times U (1)_{A}$ symmetry, where both the doublet--triplet splitting…

Probing Scalar-Mediator Quark Couplings via CLFV Lepton-Nucleon Scattering

Yuichiro Kiyo, Michihisa Takeuchi, Yuichi Uesaka +1

We investigate charged lepton flavor violating (CLFV) deep-inelastic scattering, focusing on the gluon-initiated subprocess $ℓ_{i} g \to ℓ_{j} g$ via the gluon effective operator…

Lepton flavor violating decay of true muonium: $(I^¼^{+} I^¼^{-}) \to I^¼^{\pm} e^{\mp}$

Ryotaro Minato, Akira Sato, Ryosuke Suda +1

We propose a new channel for probing charged lepton flavor violation (CLFV): the decay of true muonium into a lepton pair of different flavor, $(I^¼^{+} I^¼^{-}) \to I^¼^{\pm} e^{\mp}$ . This…

$I^¼^{-} \to e^{-} I^^{3}$ in a muonic atom as a probe for effective lepton flavor violating operators involving photon fields

Yuichi Uesaka, Masato Yamanaka, Yoshitaka Kuno

We propose the $I^¼^{-} \to e^{-} I^^{3}$ process in a muonic atom as a novel means to investigate charged lepton flavor violation (CLFV). We demonstrate its sensitivity in probing effective…
