We report on a study of exclusive radiative decays of the ϒ(1S) resonance collected with the CLEO II detector operating at the Cornell Electron Storage Ring. We present the first observation of the radiative decays ?(1S)→γπ+#x03C0;- and ϒ(1S)→ γ #x03C0;0#x03C0;0. For the dipion mass regime m#x03C0;#x03C0; > 1.0 GeV we obtain B(ϒ(1S)→ γ#x03C0;+#x03C0;-)=(6.3±1.2±1.3)×10-5 and B(ϒ(1S)→ γ#x03C0;0#x03C0;0)=(1.7±0.6±0.3)×10-5. © 2000 The American Physical Society.The measurement of sin(2β)
Proceedings of Science 3 (1999)
Abstract:
Since the first observation in 1964, CP violation remains one of the most elusive aspects of the standard model. The CDF collaboration has reported the first evidence of CP violation in the B system using the world's largest sample of B → J/ψKS0 decays. The direct measurement of sin(2β)=0.79+0.41−0.44(combined statistical and systematic error) agrees with the standard model predictions. New data collected from the B-factories and from the upgraded experiments at the Tevatron should allow a more precise measurement of sin 2β in the near future.Measurement of b quark fragmentation fractions in the production of strange and light B mesons in p(p)over-bar collisions at √s=1.8 TeV -: art. no. 092005
