N=2 supersymmetric dynamics for pedestrians
Yuji Tachikawa
We give a pedagogical introduction to the dynamics of N=2 supersymmetric systems in four dimensions. The topic ranges from the Lagrangian and the Seiberg-Witten solutions of SU(2)…
2d SCFTs from M2-branes
Kentaro Hori, Chan Y. Park, Yuji Tachikawa
We consider the low-energy limit of the two-dimensional theory on k M2-branes suspended between a straight M5-brane and a curved M5-brane. We argue that it is described by an N=(2,…
Classification of 4d N=2 gauge theories
Lakshya Bhardwaj, Yuji Tachikawa
We classify all possible four-dimensional N=2 supersymmetric UV-complete gauge theories composed of semi-simple gauge groups and hypermultiplets. We also give appropriate reference…
On the 6d origin of discrete additional data of 4d gauge theories
Yuji Tachikawa
Starting with a choice of gauge algebras, specification of a 4d gauge theory involves additional data, namely the gauge groups and the discrete theta angles. Equivalently, one need…
Dynamical Supersymmetry Breaking with T_N Theory
Kazunobu Maruyoshi, Yuji Tachikawa, Wenbin Yan +1
We demonstrate that the supersymmetry is dynamically broken in the four-dimensional SU(N) gauge theory coupled to a strongly-coupled superconformal theory T_N. This is a direct gen…
Elliptic genera of two-dimensional N=2 gauge theories with rank-one gauge groups
Francesco Benini, Richard Eager, Kentaro Hori +1
We compute the elliptic genera of two-dimensional N=(2,2) and N=(0,2) gauged linear sigma models via supersymmetric localization, for rank-one gauge groups. The elliptic genus is e…
