Gauge contribution to the 1/N F expansion of the Yukawa coupling beta function

Gauge contribution to the 1/N F expansion of the Yukawa coupling beta function

Abstract We provide a closed analytical form for the gauge contribution to the beta function of a generic Yukawa coupling in the limit of large N F , where N F is the number of heavy vector-like fermions charged under an abelian or non-abelian gauge group. The resummed expression is finite and for t...
