Textures of dimension-six operators in the SMEFT with non-invertible selection rules

Tatsuo Kobayashi, Hajime Otsuka, Morimitsu Tanimoto +1

We investigate the flavor structures of dimension-six operators in the Standard Model Effective Field Theory (SMEFT) subject to non-invertible selection rules. In particular, we cl…

GUT-motivated non-invertible symmetry as a solution to the strong CP problem and the neutrino CP-violating phase

Tatsuo Kobayashi, Hajime Otsuka, Morimitsu Tanimoto +1

The unsuppressed CP violation in QCD is a problem in the standard model. If we have some mechanism to guarantee real determinants of the quark mass matrices, the vanishing physical…

Axionless Solution to the Strong CP Problem -- two-zeros textures of the quark and lepton mass matrices and neutrino CP violation --

Morimitsu Tanimoto, Tsutomu T. Yanagida

CP invariance is a very attractive solution to the strong CP problem in QCD. This solution requires the vanishing , where the an…

Lepton mass textures from non-invertible multiplication rules

Tatsuo Kobayashi, Hajime Otsuka, Morimitsu Tanimoto +1

We study the lepton mass textures, which are derived by gauging of symmetries. We can obtain various textures for the Yukawa couplings in the charged…

More about quark Yukawa textures from selection rules without group actions

Tatsuo Kobayashi, Yume Nishioka, Hajime Otsuka +1

We study the coupling selection rules associated with non-group symmetries, i.e., gauging of symmetries. We clarify which Yukawa textures can be deriv…

Leptonic dipole operator with modular invariance in light of Muon

Takaaki Nomura, Morimitsu Tanimoto, Xing-Yu Wang

We have studied the leptonic EDM and the LFV decays relating with the recent data of anomalous magnetic moment of muon, in the leptonic dipole operator. We have adopted…
