Distinguishing anomaly-mediation from gauge-mediation with a Wino NLSP
A striking consequence of supersymmetry breaking communicated purely via the superconformal anomaly is that the gaugino masses are proportional to the gauge β-functions. This result, however, is not unique to anomaly-mediation. We present examples of “generalized” gauge-mediated models with messengers in standard model representations that give nearly identical predictions for the gaugino masse...
متن کاملRealistic Anomaly Mediation with Bulk Gauge Fields
We present a simple general framework for realistic models of supersymmetry breaking driven by anomaly mediation. We consider a 5-dimensional ‘brane universe’ where the visible and hidden sectors are localized on different branes, and the standard model gauge bosons propagate in the bulk. In this framework there can be charged scalar messengers that have contact interactions with the hidden sec...
متن کاملMinimal Deflected Anomaly Mediation
I provide a minimal method for generating a mu term and positive slepton masses within the framework of anomaly mediation. I introduce a new operator involving a hidden sector U(1) gauge field which is then canceled against a Giudice-Masiero-like μ term. No new flavor violating operators are allowed. This procedure produces viable electroweak symmetry breaking in the Higgs sector. Only a single...
متن کاملPositively-deflected anomaly mediation
We generalize the so-called “deflected anomaly mediation” scenario to the case where threshold corrections of heavy messengers to the sparticle squared-masses are positive. A concrete model realizing this scenario is also presented. The tachyonic slepton problem can be fixed with only a pair of messengers. The resultant sparticle mass spectrum is quite different from that in the conventional de...
متن کاملKähler Anomaly Effect in Anomaly Mediation Framework
We extend the anomaly mediation mechanism by including the effect due to Kähler anomaly. We give a general method analyzing the soft breaking terms in MSSM by introducing a set of parameters. One of the parameters describes the magnitude of the Kähler contribution as opposed to the ordinary super-Weyl contribution. The other parameters come from the so-called bilinear terms which are added to t...
