Short description.

Physics Motivation: measure Higgs Yukawa coupling to muons, which provides useful test for ratio of Yukawa coupling between 2nd/3rd generation leptons (with Htautau); between 2nd generation lepton/quark (with Hcc).

Search Channel: e+e- → ZH, Z→ll/qq/nunu, H→mu mu, Ecm=500 GeV.

Detector Benchmark: very sensitive to high momentum resolution/tracking efficiency, algorithm for isolated lepton tagging.

Main observables.

final observable: Branching ratio of H→ mu mu.

intermediate observables: track momentum resolutions.
