Measurement of the Oscillation Frequency for B 0 - B 0 Mixing using Hadronic B 0 Decays Belle
نویسندگان
چکیده
The oscillation frequency of B0-B0 mixing (∆md) has been measured using 29.1 fb −1 of data collected with the Belle detector at KEKB. This measurement is made through the distributions of the proper decay time difference of B pairs in events tagged as sameand opposite-flavor decays. In each event, one B is fully reconstructed in a flavor-specific hadronic decay mode, while the flavor of the other is extracted through a likelihood calculated from the b-flavor information carried in its final decay products. We obtain ∆md = (0.528± 0.017± 0.011) ps −1, where the first error is statistical and the second error is systematic. PACS: 12.15.Hh, 11.30.Er, 13.25.Hw

متن کاملB Cp -violation, Mixing and Lifetime Results from Belle
Recent results on the B CP -violation parameter sin 2φ1, the B 0 d-B 0 d mixing parameter ∆md and B-meson lifetimes are reported. The results are based on 10.5 fb of data collected with the Belle detector at KEKB. Using both semileptonic and hadronic decay modes the neutral and charged B-meson lifetimes are measured to be τ (B d) = 1.548 ± 0.035 (stat.) ps and τ (B) = 1.656±0.038 (stat.) ps. Th...
متن کاملS Mixing Using Inclusive and Semileptonic B Decays at Sld
We set a preliminary 95% C.L. exclusion on the oscillation frequency of B 0 s B 0 s mixing using a sample of 250,000 hadronic Z 0 decays collected by the SLD experiment at the SLC between January 1996 and March 1998. The analyses determine the b-hadron avor at production by exploiting the large forward-backward asymmetry of polarized Z 0 ! bb decays as well as information from the hemisphere op...

We set a preliminary 95% C.L. exclusion on the oscillation frequency of B 0 s − B 0 s mixing using a sample of 400,000 hadronic Z 0 decays collected by the SLD experiment at the SLC between 1996 and 1998. The analyses determine the b-hadron flavor at production by exploiting the large forward-backward asymmetry of polarized Z 0 → bb decays as well as information from the hemisphere opposite tha...
