Precise determination of the Higgs-chargino and Higgs-neutralino couplings in chargino and neutralino production at µ⁺ µ⁻ annihilation — •F. von der Pahlen and H. Fraas — Institut für Theoretische Physik, Universität Würzburg, Am Hubland, D-97074 Würzburg

In the minimal supersymmetric standard model (MSSM) charginos and neutralinos may be produced via s-channel Higgs exchange in µ⁺ µ⁻ annihilation at the heavy neutral Higgs resonances. These processes offer an outstanding possibility for a precise determination of the Higgs-chargino and Higgs-neutralino couplings.

We study the supersymmetric parameter space where this is an interesting possibility. We analyze the effect of the finite energy spread of the muon beams on the determination of the couplings, as well as error induced by subtracting the remaining production channels, gauge boson and slepton exchange.
