Calculating the Higgs mass in string theory (2021)
Journal Article
Abel, S., & Dienes, K. R. (2021). Calculating the Higgs mass in string theory. Physical Review D, 104(12), https://doi.org/10.1103/physrevd.104.126032

In this paper, we establish a fully string-theoretic framework for calculating one-loop Higgs masses directly from first principles in perturbative closed-string theories. Our framework makes no assumptions other than world sheet modular invariance a... Read More about Calculating the Higgs mass in string theory.

Gauged 2-form symmetries in 6D SCFTs coupled to gravity (2021)
Journal Article

We study six dimensional supergravity theories with superconformal sectors (SCFTs). Instances of such theories can be engineered using type IIB strings, or more generally F-Theory, which translates field theoretic constraints to geometry. Specificall...
