Note on arithmetic structure of modulus vacua in flux compactifications
Yukiya Furuta, Tatsuo Kobayashi, Tomoyasu Kori +3
We study modulus stabilization by background fluxes. Within the truncated complex-structure sector, the F-term conditions of the complex structure moduli are described by a holomor…
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…
Massive modes on magnetized blow-up manifold of
Tatsuo Kobayashi, Hajime Otsuka, Hikaru Uchida
We study massive modes on a magnetized blow-up manifold of . The blow-up manifold can be constructed by appropriately replacing orbifold singular points with a pa…
Residual group-like symmetries in selection rules without group actions
Jun Dong, Tatsuo Kobayashi, Shuhei Miyamoto +2
We analyze loop-induced group-like symmetries in theories where fields are labeled by basis elements of a fusion algebra constructed from the conjugacy classes of finite groups. Al…
Yukawa Textures with Enhanced Symmetries in Heterotic Calabi-Yau Compactifications
Jun Dong, Tatsuo Kobayashi, Shuhei Miyamoto +1
We clarify the structure of Yukawa couplings and mass matrices for matter fields in heterotic string theory on smooth Calabi-Yau threefolds with standard embedding. The topological…
