Soft supersymmetry breaking and finiteness
We calculate the two-loop β-functions for soft supersymmetry-breaking interactions in a general supersymmetric gauge theory, emphasising the role of the evanescent couplings and masses that areExpand
More on the axial anomaly in supersymmetric Yang-Mills theory☆
The compatibility of the Adler-Bardeen theorem with the supermultiplet containing the axial, trace, and supercurrent anomalies in N = 1 supersymmetric Yang-Mills theory is re-examined (in componentExpand
Quasi-infrared fixed points and renormalization group invariant trajectories for nonholomorphic soft supersymmetry breaking
In the MSSM the quasi-infrared fixed point for the top-quark Yukawa coupling gives rise to specific predictions for the soft-breaking parameters. We discuss the extent to which these predictions areExpand
Fermion masses and induction of the weak scale by supergravity
Abstract We discuss some problems which arise in a low-energy theory of strong and electroweak interactions when the weak scale is induced via supergravity. The main problem concerns the origin ofExpand
The effective potential, the renormalisation group and vacuum stability
We review the calculation of the the effective potential with particular emphasis on cases when the tree potential or the renormalisation-group-improved, radiatively corrected potential exhibitsExpand
The weak mixing angle and unification mass in supersymmetric SU(5)
We consider the predictions for the weak mixing angle 0w and the scale M of unification in a supersymmetric extension of SU(5). with particular emphasis on the sensitivity to the number of HiggsExpand
Naturalness and dimensional transmutation in classically scale-invariant gravity
A bstractWe discuss the nature of quantum field theories involving gravity that are classically scale-invariant. We show that gravitational radiative corrections are crucial in the determination ofExpand
A new renormalization group is presented which exploits invariance with respect to more than one scale. The method is illustrated by a simple model, and future applications to fields such as criticalExpand
Heavy particles and the ϱ parameter in the standard model
Abstract A new formalism is presented for the calculation of the contribution δϱ to ϱ = Mw2/Mz2cos2θw from heavy particles transforming according to arbitrary representations of SU(2) × U(1). AExpand
Induced gravity I: real scalar field
A bstractWe show that classically scale invariant gravity coupled to a single scalar field can undergo dimensional transmutation and generate an effective Einstein-Hilbert action for gravity, coupledExpand
