چکیده

The ongoing high precision E821 Brookhaven National Laboratory experiment on muon g22 is promising to probe a theory involving supersymmetry. We have studied the constraints on the minimal anomaly mediated supersymmetry breaking ~AMSB! model using the current data of muon g22 from Brookhaven. A scenario of seeing no deviation from the standard model is also considered, within a 2s limit of the combined error from the standard model result and the Brookhaven predicted uncertainty level. The resulting constraint is found to be complementary to what one obtains from b→s1g bounds within the AMSB scenario, since only a definite sign of m is effectively probed via b→s1g . A few relevant generic features of the model are also described for disallowed regions of parameter space.

Constraining Anomaly Mediated Supersymmetry Breaking Framework via Ongoing Muon g − 2 Experiment at Brookhaven

The ongoing high precision E821 Brookhaven National Laboratory experiment on muon g− 2 is promising to probe a theory involving supersymmetry. We have studied the constraints on minimal Anomaly Mediated Supersymmetry Breaking (AMSB) model using the current data of muon g − 2 from Brookhaven. A scenario of seeing no deviation from the Standard Model is also considered, within 2σ limit of the com...

Recent Muon g − 2 Result in Deflected Anomaly - Mediated Supersymmetry Breaking

We study the deflected anomaly-mediated supersymmetry breaking (AMSB) scenario in the light of the recent result of the muon g − 2 from Brookhaven E821 experiment. The E821 result suggests the deviation from the SM prediction, though there remain unsettled uncertainties. We find that the supersymmetric contribution to the muon g − 2 can be O(10), large enough to fill the deviation, with other e...

Constraints on explicit CP violation from the Brookhaven muon gÀ2 experiment

We use the recently derived CP phase dependent analytic results for the supersymmetric electroweak correction to gm22 to constrain the explicit CP phases in softly broken supersymmetry using the new physics effect seen in the g22 Brookhaven measurement. It is shown that the BNL data strongly constrain the CP violating phase um ~the phase of the Higgs mixing parameter m) and j2 @the phase of the...

Muon g-2 and Implications for Supersymmetry

A brief review is given of the implications of the recent Brookhaven result on the muon anomaly ( aμ) for supersymmetry. We focus mainly on the implications of the recent results for the minimal supergravity unified model. We show that the observed difference implies the existence of sparticles most of which should become observable at the Large Hadron Collider. Further, as foreseen in works pr...

g-2 of the muon in SUSY Models with Gauge Multiplets in the Bulk of Extra-Dimensions

We analyze the supersymmetric contributions to the anomalous magnetic moment of the muon (aμ) in the framework of pure and gaugino–assisted anomaly mediation models, and gaugino mediation models. In the last two models the gauge multiplets propagate in the higher dimensional bulk, providing a natural mechanism for solving the problem of negative squared slepton masses present in the pure anomal...
