Hypercharged Conformally Sequestered Gauge Mediation
The Bμ/μ solution in GMSB via the hidden sector dynamics is simple and natural. However, it has some obstacles to be physical. To circumvent this situation, we introduce the visible and the hidden branes, each of which has its own U(1) symmetry, in a five dimensional setup. In the bulk we allow Chern-Simons coupling between the visible and the hidden U(1)s which gives an enhancement of the mass...
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...
متن کاملGaugino-Assisted Anomaly Mediation
We present a model of supersymmetry breaking mediated through a small extra dimension. Standard model matter multiplets and a supersymmetry-breaking (or “hidden”) sector are confined to opposite four-dimensional boundaries while gauge multiplets live in the bulk. The hidden sector does not contain a singlet and the dominant contribution to gaugino masses is via anomaly-mediated supersymmetry br...
