Hidden selection rules, M5-instantons and fluxes in F-theory
Hidden selection rules, M5-instantons and fluxes in F-theory
We introduce a new approach to investigate the selection rules governing the contributions of fluxed M5-instantons to the F-theory four-dimensional effective action, with emphasis on the generation of charged matter F-terms. The structure of such couplings is unraveled by exploiting the perturbative and non-perturbative homological relations, introduced in our companion …
