Gauge-covariant vertex operators

High Energy Physics - Theory 2010-04-05 v2

Abstract

We derive Yang-Mills vertex operators for (super)string theory whose BRST invariance requires only the free gauge-covariant field equation and no gauge condition. Standard conformal field theory methods yield the three-point vertices directly in gauge-invariant form.
