Note on arithmetic structure of modulus vacua in flux compactifications
Yukiya Furuta, Tatsuo Kobayashi, Tomoyasu Kori +3
We study modulus stabilization by background fluxes. The supersymmetric minima satisfy a holomorphic quadratic equation. As concrete examples, we consider $T^6/(\mathbb{Z}_2\times\…

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…
