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...

We will review the connection between the six-dimensional (2,0) theory and maximally supersymmetric Yang-Mills in five dimensions (MSYM). We will discuss the implications of a conjectured relation between the two, at all energy scales, for MSYM. We...

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...
