Anomalies in family unification models from bordism classification

Tsubasa Sugeno, Hiroki Wada

We study anomalies in family unification models within the framework of the bordism classification of invertible field theories. These models are based on four-dimensional $\mathca…

Large $θ$ angle in two-dimensional large $N$ $CP^{N - 1}$ model

Tsubasa Sugeno, Takahiro Yokokura, Kazuya Yonekura

In confining large $N$ theories with a $θ$ angle such as four-dimensional $SU (N)$ pure Yang-Mills theory, there are multiple metastable vacua and it makes sense to conside…
