Precise measurement of the Higgs boson properties is an important issue of the International Linear Collider (ILC) experiment. We studied the accuracy of the Higgs mass reconstruction in the ZH->qqH multi-jet process with the Higgs mass of MH = 120 GeV at sqrt(s) = 250 GeV with the ILD detector model. In this study, we obtained the reconstructed Higgs mass of M_H = 120.79 +- 0.089 GeV and 5.3% measurement accuracy of the cross-section for ZH->qqbb with the integrated luminosity of L=250 fb^{-1} data samples.
Precise measurement of the Higgs boson properties are important issues for the International Linear Collider (ILC) project to understand the particles mass generation mechanism which strongly related to the coupling with the Higgs boson. Large Hadron
Precise measurement of the Higgs boson properties is an important issue of the International Linear Collider (ILC) experiment to verify the particles mass generation mechanism that the coupling strength between the Higgs boson and the fermions or vec
The existence of dark matter has been established in astrophysics. However, there are no dark matter candidates in the Standard Model~(SM). If the dark matter particles or their mediator can not interact with SM fermions or gauge bosons, the Higgs bo
This paper presents a full simulation study of the measurement of the production cross section ($sigma_{mathrm{ZH}}$) of the Higgsstrahlung process $mathrm{e^{+}e^{-}rightarrow ZH}$ and the Higgs boson mass ($M_{mathrm{H}}$) at the International Line
We evaluate the measurement precision of the production cross section times the branching ratio of the Higgs boson decaying into tau lepton pairs at the International Linear Collider (ILC). We analyze various final states associated with the main pro
