Abstract: In this paper, we demonstrate that the factorizations for tree amplitudes in the double-cover framework, for various theories, can be generated from the gravity amplitude in the double-cover prescription. Our method employs differential operators proposed… read more here.

Abstract: We study the modular symmetry of zero-modes on $$ {T}_1^2\times {T}_2^2 $$ and orbifold compactifications with magnetic fluxes, M1, M2, where modulus parameters are identified. This identification breaks the modular symmetry of $$ {T}_1^2\times {T}_2^2… read more here.
