Running soft parameters in SUSY models with multiple U(1) gauge factors [PDF]
Renato M. Fonseca, Michal Malinsky, Werner Porod, Florian StaubWe generalize the two-loop renormalization group equations for the parameters of the softly broken SUSY gauge theories given in the literature to the most general case when the gauge group contains more than a single abelian gauge factor. The complete method is illustrated at two-loop within a specific example and compared to some of the previously proposed partial treatments.View original: http://arxiv.org/abs/1107.2670
