Abstract

Once a light Higgs boson is discovered at a future e+e- collider, the next target at the collider will be precise measurements of the Higgs boson properties. In this paper we report a simulation study on the measurement of the ratio Br(H->cc,gg)/Br(H->bb) at center of mass energy of 300 GeV, and show the possibility to constrain MSSM parameters from the measurement.
