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 کاملExact Results in Softly Broken Supersymmetric Models
We show how recent exact results in supersymmetric theories can be extended to models which include explicit soft supersymmetry breaking terms. We thus derive new exact results for non-supersymmetric models.
متن کاملSoftly Broken N = 1 Supersymmetric QCD
We study softly broken N = 1 supersymmetric QCD with the gauge group SU(Nc) and Nf flavours of quarks for Nf > Nc + 1. We investigate the phase structure of its dual theory adding generic soft supersymmetry breking terms, i.e. soft scalar masses, trilinear coupling terms of scalar fields and gaugino masses. It is found that the trilinear coupling terms play an improtant role in determining the ...
