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…
A note on the classification of simple -modules admitting -stable lines in cross characteristic
Junbin Dong
Let be the group of diagonal matrices in , where is a prime number. Let be an algebraically closed field of characteristic not equal t…
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…
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…
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…
