We scan the minimal supersymmetric standard model parameters relevant to (g-2)μ and focus on three distinct cases with different neutralino compositions. The explanation of (g-2)μ excess at 2σ range requires the smuon (μ∼1) to be lighter than ∼500(1000)GeV for tanβ=10(50). Correspondingly the two lightest neutralinos, χ∼10, χ∼20, have to be lighter than ∼300(650)GeV and 900 (1500) GeV, respectively. We explore the prospects of searching these light neutralinos and smuons at the LHC. The upcoming run of the LHC will be able to set 95% CL exclusion limit on Mχ∼20 (∼650-1300GeV) and ml∼ (∼670-775GeV) with Mχ∼10∼100-250GeV at 3000fb-1 integrated luminosity in multilepton+ET channel.
