Title: Finding G_2 Higgs Branch of 4D rank 1 SCFTs

Abstract: In this talk, I will discuss the correspondence between 4D N=2 unitary SCFTs and 2D non-unitary CFTs. The rank one case has been shown to lead to the non-unitary CFTs with Deligne-Cvitanovic (DC) exceptional sequence of Lie groups. Utilizing our proposed method of unitarization, I will demonstrate that the unflavored characters of the DC CFTs map to the characters of the Mathur-Mukhi-Sen Sequence. Then, focusing on the example of G_2/E_6 correspondence, we demonstrate that our unitarization map holds for some discrete flavor fugacities as well. Lastly, using Galois conjugation along with our result, we propose that the G_2 Higgs branch is a sub-branch of the E_6 Higgs branch. The talk will be based on https://arxiv.org/abs/2312.00275.
