| 英文摘要 | It is difficult to measure the ww-fusion higgs production process (e(+)e(-) -> v (v) over barh) 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 -> v (v) over bar). 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 m(recoil). 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. |
