Surprising one-loop finiteness of 6D half-maximal supergravities
Yu-tin Huang, Henrik Johansson, Michele Santagata +1
In four dimensions, it has long been established that gravity coupled to matter exhibits ultraviolet divergences at one loop, irrespective of supersymmetry. Notably, the four-matte…

Non-analytic terms of string amplitudes from partial waves
Yu-tin Huang, Hynek Paul, Michele Santagata
We describe a general formalism based on the partial-wave decomposition to compute the iterative -channel discontinuity of four-point amplitudes at any loop order. As an applica…
