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 vector bosons are proportional to the mass of each particle. Thus the measurement of the branching ratio of the Higgs boson an important issue to understand the mass of each particle. In this analysis, measurement accuracy of the Higgs boson branching ratio in the ZH->qqH hadronic decay mode was studied with the cut-based analysis in Higgs mass of M_{H}=120 GeV at the center-of-mass energy of sqrt{s}=250 GeV with the ILD detector model. From the analysis, we estimate the measurement accuracy of the relative Higgs boson branching ratio of BR(H->cc)$ to BR(H->bb) as 13.68%.
The branching fraction for the decay $K^{-} to pi^{0} e bar u$ is measured using in-flight decays detected with {bf ISTRA+} setup working at the 25 GeV negative secondary beam of the U-70 PS:linebreak $Br_{K_{e3}}= (5.124 pm 0.009 (stat) pm 0.029(no
The PEN Collaboration is conducting a new measurement of the pi+ -> e+ nu branching ratio at the Paul Scherrer Institute, with the goal uncertainty of delta B/B(pie2)=5E-4 or lower. At present, the combined accuracy of all published pie2 decay measur
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 G
We carried out a feasibility study on the measurement of the branching ratio of H -> cc_bar at a future e+e- linear collider. We used the topological vertex reconstructing algorithm for accumulating secondary vertex information and the neural network
The process e+e-->mu+mu- has been studied by SND detector at VEPP-2M e+e- collider in the phi(1020)-resonance energy region. The measured effective phi meson leptonic branching ratio: B(phi->l+l-)=sqrt{B(phi->e+e-)*B(phi->mu+mu-)}=(2.89+-0.10+-0.06)*
