Crossing Symmetry in Matter Chern Simons theories at finite N and k
Shiraz Minwalla, TaTa Institute,

It has been demonstrated that 2 -> 2 scattering in `trivially' gapped theories enjoy invariance under crossing invariance. Evidence from previous computations performed at large N suggests that these crossing symmetry rules can be modified in theories with massive particles that reduce, at low energies, to nontrivial topological field theories. We present a physically motivated conjecture for the precise form of these crossing symmetry rules 

in the case of massive particles minimally coupled to Chern Simons theories. Our conjecture is completely explicit in the case that our massive particles transform in the fundamental representation of (say) $SU(N)_k$ Chern Simons theories. In person attendees (469 Lauritsen) must have a valid Caltech ID.
