DESCRIPTION:Subham Dutta Chowdhury\nConformal invariance allows additiona
 l unique parity-odd tensor-structures for three-point functions involving
  the stress tensor\, T\, and a conserved U(1) current\, j\, in 2+1 dimens
 ional conformal field theories that violate parity\, apart from the usual
  parity even structures. We  study the modifications to the crossing equa
 tions in d = 3 for the four point functionof two U(1) currents and two sca
 lars due to the presence of this parity violating term for the s-channel s
 tress tensor exchange. We show the existence of a new tower of double trac
 e operators in the t-channel whose presence is necessary for thecrossing e
 quation to be satisfied and determine the corresponding large spin parity 
 violating OPE coefficients. We then study the possible constraints on this
  parity violating coupling of the three point function from causality argu
 ments and apply them to Large N Chern Simons theories coupled to fundament
 al matter which are known to be parity violating
