Renormalization of vacuum expectation values in spontaneously broken gauge theories: Two-loop results

Understand

We complete the two-loop calculation of beta-functions for vacuum expectation values (VEVs) in gauge theories by the missing O(g^4)-terms.

• The full two-loop results are presented for generic and supersymmetric theories up to two-loop level in arbitrary R_xi-gauge.
• The results are obtained by means of a scalar background field, identical to our previous analysis.
• As a by-product, the two-loop scalar anomalous dimension for generic supersymmetric theories is presented.
