Mass renormalization in Yang-Mills supersymmetry theories
Sazdovich B. T., Tarasov O. V.
An N — 2, 4, Yang-Mills theory with a soft breaking of the expanded supersymmetry is analyzed. With N = 4, there are no divergences in the mass renormalization in any order. With N —2f the mass and charge renormalization constants are the same and contain only single-loop divergences. Calculations are carried out to two loops.
