“…We set their soft masses as (m 2 ) Q = (m 2 )Ū = (m 2 )D = (7 TeV) 2 . They satisfy the current bounds on the superparticle masses obtained at the LHC [16][17][18], and also, heavy stops are preferred to realize the Higgs boson mass of 126 GeV [19][20][21][22]. The following results do not change as long as the masses are large enough.…”

“…Since none of them has been discovered, colored superparticles are considered to be heavier than O(1) TeV [16][17][18]. Moreover, the Higgs boson mass of 126 GeV indicates the scalar tops to be as heavy as O(1-10) TeV [19][20][21][22] and/or to have a large trilinear coupling to the up-type Higgs boson [23]. These two results naively contradict with the indication of the muon g −2 anomaly that superparticles have a mass of O(100) 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.

“…We have included the large radiative corrections to the Higgs mass expected after SUSY breaking [95][96][97] by using the public code FeynHiggs [98][99][100][101] (for alternatives, see [102]), which includes all one-loop corrections and the dominant two-loop effects [103][104][105][106][107][108][109]. This gives a precise enough determination of m h (with an error of a few GeV), provided the hierarchy in the stop masses is not so large that further re-summation of logarithms is needed [110].…”

We perform a global fit to Higgs signal-strength data in the context of light stops in Natural SUSY. In this case, the Wilson coefficients of the higher dimensional operators mediating g g → h and h → γ γ, given by c g , c γ , are related by c g = 3 (1 + 3 α s /(2 π))c γ /8. We examine this predictive scenario in detail, combining Higgs signalstrength constraints with recent precision measurements of m W , Br(B → X s γ) constraints and direct collider bounds on weak scale SUSY, finding regions of parameter space that are consistent with all of these constraints. However it is challenging for the allowed parameter space to reproduce the observed Higgs mass value with sub-TeV stops. We discuss some of the direct stop discovery prospects and show how Higgs search data can be used to exclude light stop parameter space difficult to probe by direct collider searches. We determine the current status of such indirect exclusions and estimate their reach by the end of the 8 TeV LHC run.

“…It has been known for some 20 years that the lightest supersymmetric Higgs boson should weigh no more than about 140 GeV, at least in simple models [11,12,13,14,15]. Since the early 1990s, the precision electroweak noose has been tightening, and the best indication now (incorporating the negative results of searches at LEP and the Tevatron) is that the Higgs boson probably weighs less than about 140 GeV [16,17], in perfect agreement with the supersymmetric prediction.…”

CERN-PH-TH/2010-004, UMN-TH-2831/10, FTPI-MINN-10/02After reviewing the theoretical, phenomenological and experimental motivations for supersymmetric extensions of the Standard Model, we recall that supersymmetric relics from the Big Bang are expected in models that conserve R parity. We then discuss possible supersymmetric dark matter candidates, focusing on the lightest neutralino and the gravitino. In the latter case, the next-to-lightest supersymmetric particle is expected to be long-lived, and possible candidates include spartners of the tau lepton, top quark and neutrino. We then discuss the roles of the renormalization-group equations and electroweak symmetry breaking in delimiting the supersymmetric parameter space. We discuss in particular the constrained minimal extension of the Standard Model (CMSSM), in which the supersymmetry-breaking parameters are assumed to be universal at the grand unification scale, presenting predictions from a frequentist analysis of its parameter space. We also discuss astrophysical and cosmological constraints on gravitino dark matter models, as well as the parameter space of minimal supergravity (mSUGRA) models in which there are extra relations between the trilinear and bilinear supersymmetry-breaking parameters, and between the gravitino and scalar masses. Finally, we discuss models with non-universal supersymmetry-breaking contributions to Higgs masses, and models in which the supersymmetry-breaking parameters are universal at some scale below that of grand unification.
