Title: Closing in on the chargino contribution to the muon $g - 2$ in the MSSM: Current LHC constraints

Abstract

We revisit the current LHC constraints on the electroweak-ino sector parameters in the minimal supersymmetric standard model (MSSM) that are relevant to explaining the (g - 2)_μ anomaly via the dominant chargino and muon sneutrino loop. Since the LHC bounds on electroweak-inos become weaker if they decay via an intermediate stau or a tau sneutrino instead of the first two generation sleptons, we perform a detailed analysis of the scenario with a bino as the lightest supersymmetric particle (LSP) and a light stau as the next-to-lightest one (NLSP). Even in this scenario, the chargino sector parameters in the MSSM that can account for the (g - 2)_μ anomaly within 1σ are already found to be significantly constrained by the 8 TeV LHC and the available subset of the 13 TeV LHC limits. We also estimate the current LHC exclusions in the left-smuon (and/or left-selectron) NLSP scenario from multilepton searches, and further combine the constraints from the multitau and multilepton channels for a mass spectrum in which all three generations of sleptons are lighter than the chargino. In the latter two cases, small corners of the 1σ favored region for (g - 2)_μ are still allowed at present.

GUT-inspired supersymmetric model for $h \to γ γ$ and the muon $g - 2$

Journal Article Ajaib, M. Adeel ; Gogoladze, Ilia ; Shafi, Qaisar - Physical Review. D, Particles, Fields, Gravitation and Cosmology

We study a grand unified theories inspired supersymmetric model with nonuniversal gaugino masses that can explain the observed muon g-2 anomaly while simultaneously accommodating an enhancement or suppression in the h→γγ decay channel. In order to accommodate these observations and m_h≅125 to 126 GeV, the model requires a spectrum consisting of relatively light sleptons whereas the colored sparticles are heavy. The predicted stau mass range corresponding to R_γγ≥1.1 is 100 GeV≲m_τ˜≲200 GeV. The constraint on the slepton masses, particularly on the smuons, arising from considerations of muon g-2 is somewhat milder. The slepton masses in this case are predicted tomore »« less

125 GeV Higgs boson mass and muon $g 2$ in 5D MSSM

Journal Article Okada, Nobuchika ; Tran, Hieu Minh - Physical Review D

In the minimal supersymmetric standard model (MSSM), the tension between the observed Higgs boson mass and the experimental result of the muon g-2 measurement requires a large mass splitting between stops and smuons/charginos/neutralinos. Here, we consider a five-dimensional (5D) framework of the MSSM with the Randall-Sundrum warped background metric, and show that such a mass hierarchy is naturally achieved in terms of geometry. In our setup, the supersymmetry is broken at the ultraviolet (UV) brane, while all the MSSM multiplets reside in the 5D bulk. An appropriate choice of the bulk mass parameters for the MSSM matter multiplets can naturallymore »« less

A 2σ resolution of the anomaly requires relatively light sleptons, chargino and LSP neutralino. The stau turns out to be the NLSP of massmore »« less

Search for direct production of charginos, neutralinos and sleptons in final states with two leptons and missing transverse momentum in $p p$ collisions at $\sqrt{s} =$ 8 TeV with the ATLAS detector

Dataset Aad, Georges ; The ATLAS collaboration

CERN-LHC. Searches for the electroweak production of charginos, neutralinos and sleptons in final states characterized by the presence of two leptons (electrons and muons) and missing transverse momentum are performed using 20.3 fb^-1 of proton-proton collision data at sqrt(s) = 8 TeV recorded in 2012 with the ATLAS experiment at the Large Hadron Collider. No significant excess beyond Standard Model expectations is observed. Limits are set on the masses of the lightest chargino, next-to-lightest neutralino and sleptons for different lightest-neutralino mass hypotheses in simplified models. Results are also interpreted in various scenarios of the phenomenological Minimal Supersymmetric Standard Model.
