High Energy Theory Seminar

Absence of Three-Loop Four-Point Divergences in N=4 Supergravity
Tristan Dennen
1:30pm|Bloomberg Lecture Hall
We compute the coefficient of the potential three-loop divergence in pure N=4 supergravity and show that it vanishes, contrary to expectations from symmetry arguments. The recently uncovered duality between color and kinematics is used to greatly...

Jumpstarting the all-loop S-matrix of N=4 super Yang-Mills
Simon Caron-Huot
1:30pm|Bloomberg Lecture Hall
I will discuss recent progress in understanding loop-level scattering amplitudes in planar N=4 SYM. Compared with previous efforts aimed at exploiting integrability of this gauge theory, our approach differs mainly in its focus on canonical infrared...
