Exact Results for Soft Supersymmetry Breaking Parameters in Supersymmetric Gauge Theories
نویسندگان
چکیده
We obtain exact relations (valid to all orders in the coupling constant) for the running gaugino mass in supersymmetric gauge theories, treating the soft supersymmetry breaking effects in the linear approximation. If a supersymmetry breaking squark (selectron) mass term is introduced, our relation connects the renormalization group equation for this term with that for the gaugino mass. Exact relations for the threshold effects in the gaugino masses are derived. The key ingredients of our analysis is the use of the Wilsonean action and holomorphy of this action with respect to relevant parameters.

Softly broken supersymmetric Yang-Mills theories: Renormalization and non-renormalization theorems
We present a minimal version for the renormalization of softly broken Super-Yang-Mills theories using the extended model with a local gauge coupling. It is shown that the non-renormalization theorems of the case with unbroken supersymmetry are valid without modifications and that the renormalization of the soft-breaking parameters is completely governed by the renormalization of the supersymmet...
متن کاملRG invariant solutions for the soft supersymmetry breaking parameters
We show that the results for the soft couplings in supersymmetric gauge theories recently derived via the superconformal anomaly are equivalent to results obtained earlier from a consideration of exact RG-invariant trajectories. We give a full proof of these results for a general multi-coupling theory. Moreover, we demonstrate the existence of a distinct finite RG-invariant solution for the sof...
متن کاملOn the Soft Supersymmetry Breaking Parameters in Gauge - Mediated Models
Gauge mediation of supersymmetry breaking in the observable sector is an attractive idea, which naturally alleviates the flavour changing neutral current problem of supersymmetric theories. Quite generally, however , the number and quantum number of the messengers are not known; nor is their characteristic mass scale determined by the theory. Using the recently proposed method to extract supers...
متن کاملInfrared Behaviour of Softly Broken Sqcd and Its Dual
Applying the recently obtained results on the renormalization of soft supersymmetry-breaking parameters, we investigate the infrared behaviour of the softly broken supersymmetric QCD as well as its dual theory in the conformal window. Under general assumptions on βfunctions, it is shown that the soft supersymmetry-breaking parameters asymptotically vanish in the infrared limit so that superconf...
متن کاملReconstructing Supersymmetric Theories at High Energy Scales
We have studied the reconstruction of supersymmetric theories at high scales by evolving the fundamental parameters from the electroweak scale upwards. Universal minimal supergravity and gauge mediated supersymmetry breaking have been taken as representative alternatives. Pseudo-fixed point structures require the low–energy boundary values to be measured with high precision. 1. Supersymmetric t...
