▼a In this manuscript, we detail three recent calculations addressing the ultraviolet behavior of supersymmetric quantum gravity. First, we revisit the classic calculation of the two-loop pure gravity divergence. We argue that the 1/琯 divergence is regulator and duality dependent. In its place, we propose that examining the running of the scaling parameter, log 關, is a duality and regulator independent approach to assessing gravity divergences in four dimensions. We explicitly calculate the log 關 coefficient at two loops for gravity with any particle content, explicitly verifying the divergences for pure gravity, and the finiteness for supersymmetric gravities. Second, we analyze fully-integrated N=4 supergravity at one loop using the double copy. We find that there are evanescent effects at one loop that come directly from evanescent terms in pure-Yang-Mills. Using this observation, we lay the groundwork for deeper analysis of the U(1) anomaly with respect to the observed evanescent behavior. Finally, we tackle the long-standing question of the critical dimension of N=8 supergravity at five loops. We construct an integrand using the generalized double copy, expand the integrand in large loop momentum, and reduce the resulting integrals using sl(L) integration-by-parts relations. This procedure yields a critical dimension of dc = 24/5. |
