Multiple couplings and renormalization scheme ambiguities

The ambiguities inherent in renormalization are considered when using mass independent renormalization in massless theories that involve two coupling constants. We review how unlike models in which there is just one coupling constant there is no renormalization scheme in which the β-functions can be...
