Implications of the ANEC in four dimensional SCFTs
Andrea Manenti, EPFL,

The averaged null energy condition (ANEC) can be used to put constraints on the scaling dimensions of operators in a local CFTs. In some cases these are stronger than the unitarity bounds. I will consider four dimensional N=1 superconformal field theories (SCFTs) and discuss bounds on generic long and protected multiplets with spin (j,0). Some of them can be obtained analytically and others can be studied by means of a simple semidefinite programming problem. I will also briefly mention the consequences for N=2,4 SCFTs. The results of this work can also be used to prove that a certain class of N=2 chiral operators termed "exotic" must be absent from any local SCFT.

Based on [1905.09293].
