Towards a tensionless string field theory for the N=(2,0) CFT in d=6

Abstract

We describe progress in using the field theory of tensionless strings to arrive at a Lagrangian for the six-dimensional N = (2 , 0) conformal theory. We construct the free part of the theory and propose an ansatz for the cubic vertex in light-cone superspace. By requiring closure of the (2 , 0) supersymmetry algebra, we fix the cubic vertex up to two parameters.
