Dynamical CP Violation from Non-Invertible Selection Rules
Hiroshi Okada, Hajime Otsuka
We propose a novel mechanism in which leptonic CP-violating phases are generated dynamically through the radiative breaking of non-invertible selection rules. In this framework, tr…
The Minimal Supersymmetric Standard Model with Non-Invertible Selection Rules
Yuichiro Nakai, Hajime Otsuka, Yoshihiro Shigekami +1
We investigate a framework of the Minimal Supersymmetric Standard Model (MSSM) in which the quark and lepton flavor structure and suppression of flavor-changing neutral currents (F…
Heavy Field Effects on Inflationary Models in Light of ACT Data
Shuntaro Aoki, Hajime Otsuka, Ryota Yanagita
Recent results from the Atacama Cosmology Telescope (ACT), when combined with Planck and DESI datasets, indicate a scalar spectral index larger than that reported in the Plan…
Higgs-Modular Inflation
Shuntaro Aoki, Hajime Otsuka, Ryota Yanagita
We investigate the role of the Higgs field as a fundamental scalar in the Standard Model within the framework of modular inflation models, where a modulus field acts as the inflato…
Inflationary constraints on the moduli-dependent species scale in modular invariant theories
Shuntaro Aoki, Hajime Otsuka
We demonstrate that a broad class of modular inflation models predicts the emergence of new physics within an energy range of approximately \( 10^{15} \, \mathrm{GeV} \) to \( 10^{…
