Implications of exact SUSY gauge couplings for QCD

The phase structure of SUSY gauge theories can be very different from their nonsupersymmetric counterparts. Nonetheless, there is interesting information which might be gleaned from a detailed investigation of these theories. In particular, we study the pr ...

Sparticle masses from the superconformal anomaly

Riccardo Rattazzi

We discuss a recently proposed scenario where the sparticle masses are purely mediated by gravity through the superconformal anomaly. This scenario elegantly evades the supersymmetric flavor problem since soft masses, like the anomaly, are not directly sen ...

Gaugino mass without singlets

Riccardo Rattazzi

In models with dynamical supersymmetry breaking in the hidden sector, the gaugino masses in the observable sector have been believed to be extremely suppressed (below 1 keV), unless there is a gauge singlet in the hidden sector with specific couplings to t ...

Supersymmetry-breaking loops from analytic continuation into superspace

Riccardo Rattazzi

We extend to all orders in perturbation theory a method to calculate supersymmetry-breaking effects by analytic continuation of the renormalization group into superspace. A central observation is that the renormalized gauge coupling can be extended to a re ...

Unified minimal supersymmetric model with large Yukawa couplings

Riccardo Rattazzi

The consequences of assuming the third-generation Yukawa couplings are all large and comparable are studied in the context of the minimal supersymmetric extension of the standard model. General aspects of the renormalization group (RG) evolution of the par ...
