“…It is interesting to mention that such parameter regions are realized in wide SUSY models which solve the muon g − 2 anomaly (see e.g. [24][25][26][27][28][29][30]34]), in which much ingenuity is exercised in enhancing the Higgs boson mass. As we take model independent approach, the following LHC analysis will be independent of the mechanisms which realize the Higgs boson mass of 126 GeV.…”

There is more than 3σ deviation between the experimental and theoretical results of the muon g − 2. When interpreted in SUSY extensions of the SM, this anomaly suggests that some of the SUSY particles have a mass of order 100 GeV. We study searches for those particles at the LHC with particular attention to the muon g − 2. In particular, the recent results on the searches for the non-colored SUSY particles are investigated in the parameter region where the muon g − 2 is explained. The analysis is independent of details of the SUSY models. Future prospects of the collider searches are also discussed.

“…From the viewpoint of model building, the muon g − 2 is reconciled with the Higgs boson mass of 126 GeV by extending the MSSM so that extra contributions to the Higgs potential appear [24][25][26][27][28][29][30].…”

“…For instance, adding low mass vector-like particles [10] can provide significant contributions to the Higgs boson mass [11]. Another suggestion is to introduce matter-messenger mixing [12], but this can potentially reintroduce the SUSY flavor problem in mGMSB, which is undesirable.…”

Reconciling the muong−2, a 125 GeV Higgs boson, and dark matter in gauge mediation models

We present a class of models in the framework of gauge mediation supersymmetry breaking where the standard model is supplemented by additional U(1) symmetry which acts only on the third generation fermions. The messenger fields carry nontrivial U(1) charge and are vector-like particles under this symmetry. This leads to additional contribution to the soft supersymmetry breaking mass terms for the third generation squarks and sleptons. In this framework we show that the muon g − 2 anomaly, the observed 125 GeV Higgs boson mass and the detected relic dark matter abundance (gravitino in our case) can be simultaneously accommodated. The resolution of the muon g − 2 anomaly, in particular, yields the result that the first two generation squark masses, as well the gluino mass, should be 2.5 TeV, which will be tested at LHC14.

“…Some involve compressed spectra [14,15] to allow lighter coloured SUSY particles without contradicting LHC limits. Some go beyond the MSSM and reconcile the Higgs mass with a µ by lifting the Higgs mass with extra matter [16][17][18] or gauge bosons [19]. Many recently proposed models which stay within the MSSM framework involve rather split spectra, e.g.…”

Two-loop contributions to the muon (g − 2) from fermion/sfermion loops in the MSSM are presented, and an overview of the full MSSM prediction for (g − 2) is given with emphasis on the behaviour in scenarios which are compatible with LHC data, including scenarios with large mass splittings. Compared to all previously known two-loop contributions, the fermion/sfermion-loop contributions can yield the largest numerical results. The new contributions contain the important universal quantities ∆α and ∆ρ, and for large sfermion masses the contributions are non-decoupling and logarithmically enhanced. We find up to 15% (30%) corrections for sfermion masses in the 20 TeV (1000 TeV) range.
