The Ultraviolet Critical Dimension of Half-Maximal Supergravity at Three Loops
Zvi Bern, Scott Davies, Tristan Dennen
We determine the minimum dimension at which divergences first occur in half-maximal 16-supercharge supergravity at three loops. For the four-point amplitudes, we find that the crit…

Four photon production at the LHC: an application of 2->4 analytic unitarity
Tristan Dennen, Ciaran Williams
We present Next-to-Leading Order (NLO) predictions for final states, including the effects of photon fragmentation. Our results are calculated fully analytically using the t…

Enhanced Ultraviolet Cancellations in N = 5 Supergravity at Four Loop
Zvi Bern, Scott Davies, Tristan Dennen
We show that the four-loop four-point amplitudes of N = 5 supergravity are ultraviolet finite in four dimensions, contrary to expectations based on supersymmetry and duality-symmet…
