Search for Associated Chargino and Neutralino Production in e μ + ` Final States in DØ Data from Run II

چکیده
by the DØ experiment in Run II of the upgraded Fermilab Tevatron Collider at a center of mass energy of √ s = 1.96 TeV have been used to search for evidence of supersymmetry in eµ + final states accompanied by missing transverse energy. In supersymmetry models, such topologies are expected to contain contributions from associated chargino and neutralino production. Data corresponding to an integrated luminosity of 235±15 pb −1 have been analyzed. Applying all selection criteria leaves no event in the data consistent with the expectations from just the standard model. Upper limits on the cross section multiplied by the branching ratio σ(p¯ p → ˜ χ 0 2 ˜ χ ± 1) × B(3) have been set.

The status of a search for the pair production of the lightest chargino and second lightest neutralino states of the minimal supersymmetric model is presented. We have searched for four tri-lepton final states: eee, eeμ, eμμ, and μμμ, all with missing transverse energy.
متن کاملSearch for Chargino-Neutralino Pair Production at CDF
We present the results of a search for associated production of the lightest chargino and next-to-lightest neutralino using 1 fb of √ s = 1.96 TeV pp̄ data collected with the CDF detector at the Tevatron. We combine the results of several multi-lepton final states to set upper limits on the cross section times branching ratio for chargino-neutralino production as a function of the chargino mass.

Study of a Like-Sign Dilepton Search for Chargino-Neutralino Production at CDF
We propose a like-sign dilepton search for chargino-neutralino production in p p collisions at p s = 1:8 TeV, which complements the previously published trilepton search by the CDF detector using Fermilab Run I data. Monte Carlo predictions for the signal and background e ciencies indicate a signi cant increase in sensitivity to chargino-neutralino production compared to the traditional trilept...

We present a study of sensitivity of the R-parity violating SUSY searches with the upgraded DØ detector in Run II of the Fermilab Tevatron, within a SUGRA framework. We considered the lightest neutralino as an LSP that decays into a lepton and slepton (R-parity violating decay), resulting in 2e+ ≥ 4 jets or 2µ+ ≥ 4 jets final state. The analysis, based on scaling of the Run I results, shows tha...
