Chargino Pair Production in e+e− Collisions
Charginos χ1 are expected to be the lightest observable supersymmetric particles in many supersymmetric models. We present a procedure which will allow to determine the chargino mixing angles and, subsequently, the fundamental SUSY parameters M2, μ and tanβ by measurements of the total cross section and the spin correlations in e+e− annihilation to χ1 χ − 1 chargino pairs.
متن کاملChargino Pair Production at One-loop
We use the quantum corrected chargino production cross section, including information on the beam polarization and chargino helicities, to estimate the precision achievable at a 1 TeV, 500 fb Linear Collider on the determination of fundamental supersymmetric parameters from measurements of light chargino mass and production cross sections. We show that to get meaningful results higher order cor...

متن کاملChargino Pair Production at Cern Lep Ii ∗
Charginos are expected to be the lightest observable supersymmetric particles in many of the supersymmetric models. In the scenario that lighter charginios are pair-produced at CERN LEP II, we present a straightforward procedure for determining the SUSY parameters, tan β, M 2 , µ, and the electron sneutrino mass m ˜ ν up to a four-fold discrete ambiguity, although a large number of unknown SUSY...
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.
