Explaining The Muon g-2 Anomaly and New CDF II W-Boson Mass in the Framework of (Extra)Ordinary Gauge Mediation

Abstract

The SUSY contributions aμ to muon g-2 anomaly can not even reach 3σ in ordinary gauge mediated SUSY breaking (GMSB) scenarios because of the strong correlations between the colored sparticle masses and the uncolored EW sparticle masses. An interesting extension to GMSB is the (Extra)Ordinary Gauge Mediation (EOGM), which can relax the correlations between squarks and sleptons with non-universal choices for Neff,3 and Neff,2. We find that EOGM scenarios with Neff,3 Neff,2 can explain the muon g-2 anomaly within 3σ range, however can not explain the new W-boson mass by CDF II. We also propose to extend EOGM with additional adjoint 8 and 3 messengers at a high scale of order 1.0× 1014 GeV, which can shift the gauge coupling unification scale to the string scale. Such EOGM extension scenarios with adjoint messengers could spoil the unwanted gaugino mass ratios and give large SUSY contributions to aμ for Neff,3 Neff,2, which can explain the muon g-2 anomaly up to 1σ. Besides, because of the large messenger scale of order 1.0× 1014 GeV, such scenarios will in general lead to large |At| at the EW scale, which can accommodate the 125 GeV Higgs easily and possibly lead to smaller EWFT as well as BGFT. We discuss the possibility to explain the new CDF II W-boson mass in the GMSB-type framework. We find that SUSY contributions can marginally account for the new W-boson mass in the region with sleptons and wino both being light.
