K3-fibrations and Softly Broken N = 4 Supersymmetric Gauge Theories
Global geometry of K3-fibration Calabi-Yau threefolds, with Hodge number h 2,1 = r+1, is used to define N = 4 softly broken SU(r+1) gauge theories, with the bare coupling constant given by the dual heterotic dilaton, and the mass of the adjoint hypermultiplet given by the heterotic string tension. The U(r +1) Donagi-Witten integrable model is also derived from the K3-fibration structure, with t...
متن کاملFurther All-loop Results in Softly-broken Supersymmetric Gauge Theories
It is proven that the recently found, renormalization-group invariant sum rule for the soft scalar masses in softly-broken N = 1 supersymmetric gauge-Yukawa unified theories can be extended to all orders in perturbation theory. In the case of finite unified theories, the sum rule ensures the all-loop finiteness in the soft supersymmetry breaking sector. As a byproduct the exact β function for t...
متن کاملGauge Singlet Renormalisation in Softly-Broken Supersymmetric Theories
We consider the renormalisation of a softly-broken supersymmetric theory with singlet fields and a superpotential with a linear term. We show that there exist exact β-functions for both the linear term in the superpotential and the associated linear term in the Lagrangian. We also construct exact renormalisation group invariant trajectories for these terms, corresponding to the conformal anomal...

متن کاملRenormalization Properties of Softly Broken Susy Gauge Theories
In the present review we show that renormalizations in a softly broken SUSY gauge theory are not independent but directly follow from those of an unbroken or rigid theory. This is a consequence of a treatment of a softly broken theory as a rigid one in external spurion superfield. This enables one to get the singular part of effective action in a broken theory from a rigid one by a simple modif...
