un 1 99 5 CDF Results on B Decays
نویسنده
چکیده
We present recent CDF results on B lifetimes, B meson mass measurements, ratios of branching ratios, and rare decays. In addition, we present the first measurement of time-dependent Bd mixing at CDF. Several results have been updated and a few new ones included since the workshop.

Preliminary results from two recent CDF b physics analyses are presented. The first obtains sin(2β) = 0.79 +0.41 −0.44 from a measurement of the asymmetry in B 0 , B 0 → J/ψ K 0 S decays, providing the best direct indication so far that CP invariance is violated in the b sector. The second obtains new results on the parity even (A0 and A) and odd (A ⊥) polarization amplitudes from full angular ...
متن کاملFERMILAB-Conf-99/227-E CDF B spectroscopy results: B ∗ ∗ and B + c
We report on two spectroscopy results from CDF. First, we observe the orbitally excited B∗∗ mesons in B → lDX events. We find 28 ± 6 ± 3% of light B mesons produced are B∗∗ states. A collective mass fit results in a B1 mass of 5.71± 0.02 GeV/c. Secondly, we observe 20.4 −5.5 decays of B + c →J/ψl X , with a 6.40±0.39±0.13GeV/c mass and 0.46 −0.16 ± 0.03 ps lifetime. The production rate is in re...

We present recent CDF results based on approximately 1 fb −1 of p¯ p collisions at √ s = 1.96 TeV delivered at Fermilab Tevatron. Results shown include the observation of the Bs oscillation frequency, the first observation of bottom baryon Σ (*)± b states, updates on B hadrons lifetimes, and searches for rare decays in the b → sµ + µ − transition and in charmless two-body B decays.
