Measurement of Higgs Branching Ratio at ILC

Measurement of Higgs branching ratio is necessary to investigate Higgs coupling to particle masses. Especially, it is the most important program to measure the branching ratio of H → bb̄ and H → cc̄ at the international linear collider (ILC). We have studied the measurement accuracy of Higgs branching ratio at ILC with √ s = 250 GeV by using ZH → νν̄H events. We obtained the Higgs branching ratio ...

Measurement of the Dalitz-decay branching ratio of the π

The ratio B = Γ (π → eeγ)/Γ (π → γγ) is measured by comparing the production rates of the π in the two decay channels. The analysis is based on approximately four million hadronic decays of the Z boson recorded by the ALEPH detector in the years 1991 to 1995. The value of B is determined to be (1.140 ± 0.041)%. A recalculation of the Particle Data Group world average gives rise to a slightly im...
