A PRECISION MEASUREMENT OF THE BRANCHING RATIO K+ -+~+.~~/K++p+u~ *

A measurement of the branching ratio K+-P~+~~~/K~--+~~I/,, was made using stopped kaons from pp annihilations at rest and a. magnetic spectrometer to measure the momenta of the charged decay product to the 1% to 1.5% level. The determination is based on 45,500 events passing final data cuts. The resulting ratio is .3329 f .0047 (statistical) f.OO1O (systematic). Submitted to Physical Review D. ...

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 ...
