Explaining (g − 2) μ with multi-TeV sleptons

Explaining (g − 2) μ with multi-TeV sleptons

Abstract We present a supersymmetric extension of the Standard Model in which the new physics contributions to the anomalous magnetic moment of the muon can be more than an order of magnitude larger than in the minimal supersymmetric Standard Model. The extended electroweak symmetry breaking sector...
