Abstract

We compute current correlators of the $C P$ $^{N - 1}$ field theory in 2+1 dimensions, both at the critical point and in the phase with spontaneously broken $SU (N)$ symmetry. Universal constants are obtained to next-to-leading order in the $1 / N$ expansion. Implications are noted for quantum critical points of antiferromagnets and their vicinity.
