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...

In this talk we take the first steps towards a new framework for computing two-loop amplitudes, based on unitarity rather than Feynman diagrams. In this approach, the two-loop amplitude is first expanded in a basis of integrals. The expansion...

I'll evaluate the possibility of searching for the Higgs boson in channels with multiple non-resonant leptons in light of recent advances in multi-lepton search techniques at the LHC. The total multi-lepton Higgs signal exceeds the four lepton gold...

The holographic RG of Anti-De Sitter gives a powerful clue about the underlying AdS/CFT correspondence. The question is whether similar hints can be found for the heretofore elusive holographic dual of De Sitter. The framework of stochastic...
