Muon $g-2$ in Gauge Mediation without SUSY CP Problem
TL;DR: In this article, the authors discuss gauge mediated supersymmetry breaking models which explain the observed muon anomalous magnetic moment and the Higgs boson mass simultaneously, without violating the relation motivated by the grand unification theory (GUT) The naive violation of the GUT relation, however, ends up with the CP problem.

Abstract: We discuss gauge mediated supersymmetry breaking models which explain the observed muon anomalous magnetic moment and the Higgs boson mass simultaneously The successful explanation requires the messenger sector which violates the relation motivated by the grand unification theory (GUT) The naive violation of the GUT relation, however, ends up with the CP problem We propose a model in which the phases of the gaugino masses are aligned despite the violation of the GUT relation We also consider a model which generates the $\mu$-term and the additional Higgs soft masses squared without causing CP violation As a result, we find a successful model which explains the muon anomalous magnetic moment and the Higgs boson mass The model is also free from the CP, flavor-changing neutral current and the lepton flavor violation problems caused by the subdominant gravity mediation effects

I and i
TL;DR: There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.

Radiative neutrino masses, lepton flavor mixing and muon g − 2 in a leptoquark model
TL;DR: In this article, the neutrino masses are generated via one-loop corrections resulting from a mixing between S1 and R 2, which is a mixture of lepton flavor mixing.

GUT-constrained supersymmetry and dark matter in light of the new (g − 2)μ determination
TL;DR: In this paper, the authors revisited the issue in the framework of some unified SUSY models with different GUT boundary conditions on the soft masses, and showed that in these unified frameworks the above two general patterns of DM can also be found, and thus the muon anomaly can also accommodated, unlike in the simplest frameworks of the CMSSM or the NUHM.

TL;DR: In this article, the authors investigate the latest LHC constraints on models that explain the anomaly by their chargino contribution to the muon anomalous magnetic moment (g-2), and show that the parameter regions where sleptons are lighter than charginos are strongly disfavored.

Heavy squarks and light sleptons in gauge mediation. From the viewpoint of 125 GeV Higgs boson and muon g − 2
TL;DR: In this article, the authors investigated scenarios with heavy squarks and light sleptons, motivated by the recent discovery of the Higgs boson and the deviation of the muon anomalous magnetic moment (g − 2) from the SM prediction.

TL;DR: In this paper, the electroweak (EW) sector of the minimal super-ymmetric standard model (MSSM) can account for a variety of experimental data, including the observed Dark Matter (DM) content of the universe via co-annihilation with the next-to-LSP (NLSP) particle.
