ZH后坐质量分析

Analysis of ZH recoil mass

Kazutoshi Ito

摘要:

希格斯粒子质量的精确测量是国际直线对撞机(ILC)最重要的项目。利用e+e- -> ZH过程,即使希格斯玻色子玻色子衰变为不可见粒子,也可以用Z玻色子衰变产生的两条轻子径迹来测量希格斯玻色子玻色子的质量。本文报道了在积分亮度为250 fb ~(-1)的条件下,在sqrt{s}=250 GeV处对ZH -> 11 X的反冲质量和截面的测量精度。

英文摘要:

The precise measurement of the Higgs mass is the most important program at International Linear Collider (ILC). Using e+e- -> ZH process, the mass of Higgs boson can be measured by two lepton tracks from decay of Z boson, even if the Higgs boson decays into invisible particles. We report the measurement accuracy on the Higgs recoil mass and the cross sections for ZH -> llX at sqrt{s}=250 GeV with the integrated luminosity of 250 fb-1.
