I will discus quantum field theory operators supported on 'complete' light cones, which are a certain completion of ordinary light cones that I will define in the talk. I will show, by a simple conformal transformation, that in CFTs and near-CFTs...

Massless particle states carry integer or half-integer spin about themomentum axis, or "helicity". Lorentz symmetry allows for helicity states to mix under boosts (like massive particle polarizations); such mixing is not understood theoretically and...

At the tree level, the maximally helicity violating amplitudes of N gauge bosons in open superstring theory and of N gravitons in supergravity are known to have simple representations in terms of tree graphs. For superstrings, the graphs encode...

N=1 supersymmetric SU(2) gauge theory with 4 flavors has not only the usual Seiberg dual description, but also the Intriligator-Pouliot dual as an Sp(1) gauge theory, and yet another one found by Csaki, Schmaltz, Skiba and Terning (CSST). We show...
