Higgs Radiation off Quarks in the Standard Model and supersymmetric Theories at e+e- Colliders

Abstract

Yukawa couplings between Higgs bosons and quarks in the Standard Model (SM) and supersymmetric theories can be measured in the processes e+e- -> Q\bar{Q} + Higgs. The cross sections and Higgs energy distributions of these processes in the SM and minimal supersymmetric model have been determined including the complete set of next-to-leading order QCD corrections for all channels.
