A precise measurement of the B0 meson oscillation frequency
The oscillation frequency, md , of B0 mesons is measured using semileptonic decays with a D− or D∗− meson in the final state. The data sample corresponds to 3.0 fb−1 of pp collisions, collected by the LHCb experiment at centre-of-mass energies √ s = 7 and 8 TeV. A combination of the two decay modes gives md = (505.0 ± 2.1 ± 1.0) ns−1, where the first uncertainty is statistical and the second is...
متن کاملMeasurement of the B 0 B 0 oscillation frequency
The oscillation frequency ∆md of B 0B0 mixing is measured using the partially reconstructed semileptonic decay B0 → l−νD∗+X. The data sample was collected with the CDF detector at the Fermilab Tevatron collider during 1992–1995 by triggering on the existence of two lepton candidates in an event, and corresponds to about 110 pb−1 of p̄p collisions at √ s = 1.8 TeV. We estimate the proper decay ti...
متن کاملMeasurement of the Oscillation Frequency for B 0 - B 0 Mixing using Hadronic B 0 Decays
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 oth...
متن کاملMeasurement of the ratio of B+ and B0 meson lifetimes.
The ratio of the B+ and B0 meson lifetimes was measured using data collected in 2002-2004 by the D0 experiment in Run II of the Fermilab Tevatron Collider. These mesons were reconstructed in B-->mu(+)nuD(*-)X decays, which are dominated by B0 and B-->mu(+)nuD 0X decays, which are dominated by B+. The ratio of lifetimes is measured to be tau(+)/tau(0)=1.080+/-0.016(stat)+/-0.014(syst).
