Global anomalies in 8d supergravity

Yasunori Lee, Kazuya Yonekura

We study gauge and gravitational anomalies of fermions and 2-form fields on eight-dimensional spin manifolds. Possible global gauge anomalies are classified by spin bordism groups…

Matching higher symmetries across Intriligator-Seiberg duality

Yasunori Lee, Kantaro Ohmori, Yuji Tachikawa

We study higher symmetries and anomalies of 4d $so (2 n_{c})$ gauge theory with $2 n_{f}$ flavors. We find that they depend on the parity of $n_{c}$ and $n_{f}$ , the global form of…

Comments on compatibility between Conformal symmetry and Continuous higher-form symmetries

Yasunori Lee, Yunqin Zheng

We study the compatibility between the conformal symmetry together with the unitarity and the continuous higher-form symmetries. We show that the d-dimensional unitary conformal fi…

Topological terms of (2+1)d flag-manifold sigma models

Ryohei Kobayashi, Yasunori Lee, Ken Shiozaki +1

We examine topological terms of $(2 + 1)$ d sigma models and their consequences in the light of classifications of invertible quantum field theories utilizing bordism groups. In parti…

Some comments on 6d global gauge anomalies

Yasunori Lee, Yuji Tachikawa

Global gauge anomalies in $6 d$ associated with non-trivial homotopy groups $π_{6} (G)$ for $G = S U (2)$ , $S U (3)$ , and $G_{2}$ were computed and utilized in the past. In the modern bordism…

$S L (2, Z)$ action on QFTs with $Z_{2}$ symmetry and the Brown-Kervaire invariants

Lakshya Bhardwaj, Yasunori Lee, Yuji Tachikawa

We consider an analogue of Witten's $S L (2, Z)$ action on three-dimensional QFTs with $U (1)$ symmetry for $2 k$ -dimensional QFTs with $Z_{2}$ $(k - 1)$ -form symmetry. We…

Revisiting Wess-Zumino-Witten terms

Yasunori Lee, Kantaro Ohmori, Yuji Tachikawa

We revisit various topological issues concerning four-dimensional ungauged and gauged Wess-Zumino-Witten (WZW) terms for $S U$ and $S O$ quantum chromodynamics (QCD), from the modern…
