On E7+1/2 gauge theory

Title: On E7+1/2 gauge theory
Abstract: We propose that an exotic gauge theory based on the intermediate Lie algebra E7+1/2 naturally appears in the landscape of 6d F-theory. We give strong evidence of this proposal with 6d anomaly cancellation, dual M-theory geometry and elliptic genus of the single-string worldsheet CFT.
