Testing SUSY models for the muon $g-2$ anomaly via chargino-neutralino pair production at the LHC

Nonuniversal gaugino mass models can naturally account for the dark matter relic density via the bulk annihilation process with relatively light bino LSP and right sleptons in the mass range of $\sim 100\mathrm{GeV}$, while accommodating the observed Higgs boson mass of $\sim 125\mathrm{GeV}$ with TeV scale squark/gluino masses. A class of these models can also account for the observed muon g-2 anomaly via SUSY loops with wino and left sleptons in the mass range of 400–700 GeV. These models can be tested at LHC via electroweak production of charged and neutral wino pair, leading to robust trilepton and same sign dilepton signals. We investigate these signals along with the standard model background for both 8 and 13 TeV LHC runs.
