Description
In the face of theoretical and experimental difficulties in directly probing string theory in its natural, high-energy regime, one hopes that its low-energy regime feature general properties arising from UV/IR mixing. Concretely, I will discuss how the infrared data - potentials, gauge couplings, Wilson coefficients - of gravitational effective theories arising from worldsheet string theory (specifically closed-string sectors at one-loop level) is constrained by conformal and modular invariance. I will comment on how the resulting scaling relations connecting these quantities reflects expectations from holographic and swampland considerations.
