Beta-decay branching ratios of 62Ga
Beta-decay branching ratios of Ga have been measured at the IGISOL facility of the Accelerator Laboratory of the University of Jyväskylä. Ga is one of the heavier Tz = 0, 0 → 0 β-emitting nuclides used to determine the vector coupling constant of the weak interaction and the Vud quark-mixing matrix element. For part of the experimental studies presented here, the JYFLTRAP facility has been empl...
متن کاملBranching ratios for the β decay of 21 Na
We have measured the beta-decay branching ratio for the transition from 21Na to the first excited state of 21Ne. A recently published test of the standard model, which was based on a measurement of the β-ν correlation in the decay of 21Na, depended on this branching ratio. However, until now only relatively imprecise (and, in some cases, contradictory) values existed for it. Our new result, 4.7...
متن کاملK(k)x: Decay Distributions, Branching Ratios and Cp Asymmetries
The semi-inclusive charmless hadronic decays B → K(K)X , where X is a hadronic recoil system containing no charmed and strange particles, are useful for studying direct CP violation and determining the weak phase γ . Direct CP violation can also be studied with exclusive or inclusive charmless hadronic B decays. Although theoretical uncertainties in inclusive decays may be small, it is experime...
متن کاملBranching ratios and CP asymmetries in the decay B-->VV.
We carry out a systematic study of branching ratios, angular correlations, and CP asymmetries in the decay of neutral and charged B mesons to final states consisting of two vector mesons. The renormaiization-group-improved effective Hamiltonian is evaluated in the vacuum insertion (factorization) approximation. Okubo-Zweig-Iizuka suppressed aud annihilation terms are neglected. Current matrix e...
متن کاملBeauty Semileptonic Branching Ratios
Recent measurements of inclusive and exclusive semileptonic b branching ratios are reviewed. Model-independent analyses from ARGUS and CLEO connrm the value B(b ! ``X) = 10:4%, while new analyses from ALEPH obtain higher values above 11%. The diierence is not consistent with measured values of b hadron lifetime. New measurements of B(B ! D ? ``) from CLEO and ALEPH are in good agreement. First ...
