Multiloop soft theorem for gravitons and dilatons in the bosonic string
Abstract We construct, in the closed bosonic string, the multiloop amplitude involving N tachyons and one massless particle with 26 − D compactified directions, and we show that at least for D > 4, the soft behaviors of the graviton and dilaton satisfy the same soft theorems as at the tree level,...
