Thermodynamic limit for SO(2N) gauge theories with spinors/conjugate spinors

Xiaobin Li, Futoshi Yagi

In this paper, we investigate five-dimensional $N = 1$ supersymmetric $S O (2 N)$ gauge theories coupled to hypermultiplets in spinor/conjugate spinor representation based o…

Topological Vertex for Symmetric matter

Sung-Soo Kim, Xiaobin Li, Futoshi Yagi +1

We propose a novel topological vertex formalism for 5d $N = 1$ SU( $N$ ) gauge theory with a hypermultiplet in the symmetric tensor representation, whose Type IIB brane const…

Topological vertex formalism with O5-plane

Sung-Soo Kim, Futoshi Yagi

We propose new topological vertex formalism for Type IIB $(p, q)$ 5-brane web with an O5-plane. We apply our proposal to 5d $N = 1$ Sp(1) gauge theory with $N_{f} = 0, 1, 8$ flavo…

O-vertex, O7 $^{+}$ -plane, and Topological Vertex

Sung-Soo Kim, Xiaobin Li, Futoshi Yagi +1

We revisit the instanton partition function for 5d $N = 1$ SO( $N$ ) gauge theories compactified on S $^{1}$ , computed from the topological vertex formalism with the O-vertex ba…

Freezing and BPS jumping

Sung-Soo Kim, Xiaobin Li, Satoshi Nawata +1

We report a novel BPS jumping phenomenon of 5d $N = 1$ supersymmetric gauge theories whose brane configuration is equipped with an O $7$ -plane. The study of the relation bet…
