“…In fact, some of the representative SUSY-breaking mediation mechanisms such as the minimal supergravity and the gauge mediation cannot satisfy the above three phenomenological requirements simultaneously, (i) providing the Higgs boson mass of 126 GeV, (ii) avoiding the constraints from the direct searches at the LHC, and (iii) solving the muon g − 2 anomaly (see ref. [24] for a study on the minimal supergravity).…”

“…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].…”

“…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.

“…As already emphasized in refs. [126,127], the regions of the parameter space that lead to a 125 GeV Higgs generally result in a small a SUSY µ which is in tension with experimental results using e + e − experimental data [100,104]. However, if tau data is used, the discrepancy is smaller [103].…”

We investigate signatures induced by a very light pseudoscalar Higgs in neutralino decays in the Next-to-Minimal Supersymmetric Standard Model (NMSSM) and determine their observability at the LHC. We concentrate on scenarios which feature two light scalar Higgs bosons (one of them is SM-like with a mass of 125 GeV and a singlet-like lighter one) with a very light (singlet-like) pseudoscalar Higgs in the mass range 2m τ < m a 0 1 < 2m b . We consider neutralino-chargino pair production and the subsequent decay χ 0 2,3 → χ 0 1 a 0 1 , which leads to topologies involving multi-leptons and missing transverse energy. We determine a set of selection cuts that can effectively isolate the signal from backgrounds of the Standard Model or the Minimal Supersymmetric Standard Model. We also exemplify the procedure with a set of benchmark points, for which we compute the expected number of events and signal strength for LHC with 8 TeV center of mass energy. We show that this signal can already be probed for some points in the NMSSM parameter space.

“…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.
