Neutralinos and Sleptons at the LHC in Light of Muon Anomalous Magnetic Moment

We study the possibility of detection of the neutralinos and sleptons of the minimal supersymmetric standard model (MSSM) that explains the (g − 2)µ anomaly at the LHC. In this thesis, we scan the MSSM parameter space that is consistent with the (g − 2)µ excess and highlight three distinct cases with different neutralino compositions. The explanation of (g−2)µ excess at 2σ range requires the smuon (µ1) to be lighter than ∼ 500 (1000) GeV for tan β = 10 (50). Correspondingly the two lightest neutralinos, X^0 1 , X^ 0 2 , have to be lighter than ∼ 300 (650) GeV and 900 (1500) GeV respectively. We search these light smuons and neutralinos at the LHC in multilepton + E/T final states. The ongoing run of the LHC will set 95% CL exclusion limit on Mx^0 2 (∼ 650 − 1300 GeV) and ml (∼ 670 − 775 GeV) with Mx^0 1 ∼ 100 − 250 GeV at 3000 fb^−1 integrated luminosity in the aforementioned channel.
