The axion mass in modular invariant supergravity [rapid communication]
Abstract
When supersymmetry is broken by condensates with a single condensing gauge group, there is a nonanomalous Rsymmetry that prevents the universal axion from acquiring a mass. It has been argued that, in the context of supergravity, higher dimension operators will break this symmetry and may generate an axion mass too large to allow the identification of the universal axion with the QCD axion. We show that such contributions to the axion mass are highly suppressed in a class of models where the effective Lagrangian for gaugino and matter condensation respects modular invariance (Tduality).
