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…
More about modular symmetries and non-invertible properties in magnetized compactifications
Tatsuo Kobayashi, Shuhei Miyamoto, Riku Nakano +2
We study the modular symmetry in magnetized compactifications. The zero-modes with different Scherk-Schwarz phases transform each other. A generic model does not include modes with…
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…
Non-Invertible Selection Rules on Heterotic Non-Abelian Orbifolds
Tatsuo Kobayashi, Ryusei Nishida, Hajime Otsuka
We investigate coupling selection rules in heterotic string theory on non-Abelian orbifolds. Since boundary conditions on the orbifolds are classified by conjugacy classes of space…
On discrete gauging and non-invertible selection rules
Jun Dong, Tim Jeric, Tatsuo Kobayashi +2
We clarify selection rules of conjugacy classes of several finite discrete groups where we deal with both gauged and ungauged cases. We find that the selection rules enjoy finite A…
Coupling Selection Rules in Heterotic Calabi-Yau Compactifications
Jun Dong, Tatsuo Kobayashi, Ryusei Nishida +2
We study coupling selection rules of chiral matter fields in heterotic string theory with standard embedding. These selection rules are determined by topological properties of Cala…
Flavor symmetries from modular subgroups in magnetized compactifications
Tatsuo Kobayashi, Kaito Nasu, Ryusei Nishida +2
We study the flavor structures of zero-modes, which are originated from the modular symmetry on and its orbifold with magnetic fluxes. We introduce the constrai…
