3 3 B c Results from CDF
نویسنده
چکیده
CDF Run II detector has accumulated about 360 pb ¡ 1 data using dimuon triggers in p ¯ p collisions collected at ¢ s = 1.96 TeV. We report a first evidence for the B£ c meson in the fully reconstructed decay channel B c ¤ J¥ ψπ, and its mass measurement. In addition, we present ratio of branching fractions in B c ¤ J¥ ψ¦ modes, normalized to the B c ¤ J¥ ψK mode.

FERMILAB-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...
متن کاملMeasurement of Heavy Quark cross-sections at CDF
The measurement of heavy quark cross-sections provides important tests of the QCD theory. This paper reviews recent measurements of single b-quark and correlated b-quark cross-sections at CDF. Two new measurements of the single b-quark production at CDF agree with the first result from CDF Run II. This clarifies the experimental situation and confirms the recent agreement of theoretical predict...
متن کاملTop Quark Mass Measurements at Cdf
The mass of the top quark Mtop is interesting both as a fundamental parameter of the standard model and as an important input to precision electroweak tests. The Collider Detector at Fermilab (CDF) has a robust program of top quark mass analyses, including the most precise single measurement, Mtop = 173.4 ± 2.8 GeV/c 2 , using 680 pb −1 of p¯ p collision data. A combination of current results f...
متن کاملCombination of Single Top Quark Production Results from CDF
Recently, the CDF experiment at the Fermilab Tevatron has used complementary methods to make multiple measurements of the singly produced top quark cross section. All analyses use the same dataset with more than 2 fb of CDF data and event selection based on W + 2 or W + 3 jet events with at least one b-tagged jet. However, due to differences in analysis techniques these results are not fully co...
متن کاملBc meson production at the Tevatron Revisited
CDF recently measured the quantity σ(B + c ) σ(B+) BR(B c →J/ψlν) BR(B+→J/ψK+) , from which we determine the ratio σ(B + c ) σ(b̄) to be (2.08 −0.95) × 10−3. If we interpret this ratio as a fragmentation probability, we show that this ratio is consistent with the prediction by perturbative QCD Bc fragmentation function of Braaten, Cheung, and Yuan. We also estimate the parameter mc (charm quark ...
