Symmetric point quartic gluon vertex and momentum subtraction

Understand

We compute the full one loop correction to the quartic vertex of QCD at the fully symmetric point.

• This allows us to define a new momentum subtraction (MOM) scheme in the class of schemes introduced by Celmaster and Gonsalves.
• Hence using properties of the renormalization group equation, the two loop renormalization group functions for this scheme are given.
