MHV leaf amplitudes from parafermions

Abstract We give a dual CFT representation of MHV leaf amplitudes in the large N and semiclassical limit in terms of non-compact parafermions and a single affine Kac-Moody current for SO(N). This representation is consistent with the other 2D CFT realization of 4D leaf amplitudes proposed in the lit...

description Abstract We give a dual CFT representation of MHV leaf amplitudes in the large N and semiclassical limit in terms of non-compact parafermions and a single affine Kac-Moody current for SO(N). This representation is consistent with the other 2D CFT realization of 4D leaf amplitudes proposed in the literature, which is based on a dressed Liouville theory. The equivalence between the two CFT descriptions arises from the H 3 + $$ {H}_3^{+} $$ WZW-Liouville correspondence, applied to the SL(2, ℝ)/U(1) coset theory in the spectrally flowed sector.
