Description
We study the muon $(g-2)_{\mu}$ anomaly in light of neutralino dark matter and the LHC. We scan the MSSM parameters relevant to $(g-2)_{\mu}$ and focus on three different cases with different neutralino compositions. For $\tan\beta=10$, we find that the 2$\sigma$ range of $(g-2)_{\mu}$ requires the smuon ($\tilde{\mu}_1$) to be lighter than $\sim$ 500 GeV. The neutralinos, $\tilde{\chi}^{0}_{1},\tilde{\chi}^{0}_{2}$, have to be lighter than $\sim$ 300 GeV and $900$ GeV respectively. In contrast, for $\tan\beta=50$, the corresponding upper limits are $\sim 1$ TeV for $\tilde{\mu}_1$ and $\sim 650$ GeV for $\tilde{\chi}^{0}_{1}$ and 1 TeV for $\tilde{\chi}^{0}_{2}$. We thereby study the prospects of searching these light smuons and neutralinos at the LHC, in conjunction with constraints coming from indirect detection experiments of dark matter.
