Superstring field theory expresses the perturbative S-matrix of superstring theory as a sum of Feynman diagrams each of which is manifestly free from ultraviolet divergences. The interaction vertices fall off exponentially for large space-like external momenta making the ultraviolet finiteness property manifest. but blow up exponentially for large time-like external momenta making it ... https://herbsdailyes.shop/product-category/lozenges/
