Using the e^{+/-} mu^{-/+} + E^{miss}_T signature in the search for supersymmetry and lepton flavour violation in neutralino decays
The LHC (CMS) discovery potential of the $e^{\pm}μ^{\mp} + E^{miss}_T$ signature in the search for supersymmetry and lepton flavour violation in neutralino decays is studied. A detailed study is done for the CMS test points LM1-LM9. It is shown that for the point LM1 it is possible to detect lepton flavour violation in neutralino decays with lepton flavour violating branching $Br(\tildeχ^0_2 \to μ^{\pm}e^{\mp}\tildeχ^0_1) \geq 0.04 Br(\tildeχ^0_2 \to e^{+}e^{-}\tildeχ^0_1, μ^{+}μ^{-} \tildeχ^0_1)$ for an integral luminosity $10 fb^{-1}$. A discovery potential in the mSUGRA-SUSY scenario with $\tan β= 10, ~sign(μ) = +$ in the $(m_0, m_{1/2})$ plane using the $e^{\pm}μ^{\mp} + E^{miss}_T$ signature is determined.
