Abstract

The precision measurements of the Higgs properties is crucial for a better understanding of electroweak symmetry breaking. It can be first achieved at the ILC\pciteBehnke2013 at √(s)=250\rm ~GeV via the Higgs-strahlung production process e⁺e^-→ ZH. The hadronic decay mode Z→ qq constitutes more than 65% of the total, a factor 10 more than Z→ μμ. An analysis based solely on the Z jet pair information could thus lead to a high statistics and provide a minimum biased Higgs sample. A study of the feasibility of such analysis is shown here, based on e⁺e^- simulated collisions at 250\rm ~GeV in center of mass, for the equivalent integrated luminosity of 500\rm ~fb^-1 and using a fast simulation of the ILD detector.
