英文摘要Abstract it is difficult to measure the ww-fusion higgs production process ( e + e ? → ν ν ˉ h ) at a lepton collider with a center of mass energy of 240-250 gev due to its small rate and the large background from the higgsstrahlung process with an invisible z ( e + e ? → hz , z → ν ν ˉ ) . we construct a modified recoil mass variable, m recoil p , defined using only the 3-momentum of the reconstructed higgs particle, and show that it can separate the ww-fusion and higgsstrahlung events better than the original recoil mass variable mrecoil. consequently, the m recoil p variable can be used to improve the overall precisions of the extracted higgs couplings, in both the conventional framework and the effective-field-theory framework. we also explore the application of the m recoil p variable in the inclusive cross section measurements of the higgsstrahlung process, while a quantitive analysis is left for future studies.
