Using the e{sup {+-}} {mu}{sup {+-}} + E{sub T}{sup miss} signature in the search for supersymmetry and lepton-flavor violation in neutralino decays

Journal Article · · Physics of Atomic Nuclei
The LHC (CMS) discovery potential in the search for supersymmetry and lepton-flavor violation in neutralino decays using the e{sup {+-}} {mu}{sup {+-}} + E{sub T}{sup miss} signature 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-flavor violation in neutralino decays with lepton-flavor-violating branching Br({sigma}-tilde{chi}{sub 2}{sup 0}) {sigma} {sup {yields}} {mu}{sup {+-}}e{sup {+-}}SIGMA--tilde{chi}{sub 1}{sup 0}) {sigma} {>=} 0.04 Br({sigma}-tilde{chi}{sub 2}{sup 0}) {sigma} {sup {yields}} e{sup +}e{sup -} {sigma}-tilde{chi}{sub 1}{sup 0}) {sigma}, {mu}{sup +} {mu}{sup -} {sigma}-tilde{chi}{sub 1}{sup 0}) {sigma}) for an integral luminosity of 10 fb{sup -1}. The discovery potential in the mSUGRA-SUSY scenario with tan {beta} = 10, sgn({mu}) = + in the (m{sub 0}, m{sub 1/2}) plane using the e{sup {+-}} {mu}{sup {+-}} + E{sub T}{sup miss} signature is determined.
