Charged Higgs and Stau Production in Anomaly Mediated Supersymmetry Breaking

Charged Higgs production in association with staus in electron positron annihilation is a signal of supersymmetry with bilinear R-Parity violation. In this model, neutrino masses and mixing angles are generated due to mixing with neutralinos. We show how parameters related to neutrino physics can be determined at a $500 {\mathrm fb}^{-1}$ Linear Collider from measurements of charged Higgs and stau production cross sections and decay rates. This can be achieved in AMSB where charged Higgs and stau can have similar masses.

Chargino 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 ${\mathrm fb}^{-1}$ 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 corrections should be included.
