Discovery of the Bc Meson
We report on the rst observation of the bottom-charm mesons B c through the decay mode B c ! J==ìn 1.8 TeV pp collisions using the CDF detector at the Fermilab Tevatron. A t of background and signal contributions to the observed J==`mass distribution yielded 20:4 +6:2 ?5:5 events from B c mesons. A t to the same distribution with background alone was rejected at the level of 4.8 standard deviat...
متن کاملFirst observation of B0s→J/ψf0(980) decays
First observation of B 0 s → J /ψ f 0 (980) decays ✩ .LHCb Collaboration a r t i c l e i n f o a b s t r a c t Using data collected with the LHCb detector in proton–proton collisions at a centre-of-mass energy of 7 TeV, the hadronic decay B 0 s → J /ψ f 0 (980) is observed. This CP eigenstate mode could be used to measure mixing-induced CP violation in the B 0 s system. Using a fit to the π + π...
متن کامل0 v 1 6 M ay 2 00 5 Observation of Parity Violation in the Ω − → Λ K − Decay
The α decay parameter in the process Ω − → ΛK − has been measured from a sample of 4.50 million unpolarized Ω − decays recorded by the HyperCP (E871) experiment at Fermilab and found to be [1.78±0.19(stat)±0.16(syst)]×10 −2. This is the first unambiguous evidence for a nonzero α decay parameter, and hence parity violation, in the Ω − → ΛK − decay.
متن کاملSeparating Different Models from Measuring α , β , γ
New physics effects on the B 0 − ¯ B 0 mixing and B-decay amplitudes are discussed. By a combined analysis, the models of new physics can be partially distinguished. It is emphasized that the extraction of unitarity angles β and γ through rare decay K → πν˜ν and charged B decay B ± → DK ± respectively is not likely to be affected by new physics. Such an observation could be used to distinguish ...
