Measurement of CP violation at the Υ ( 4 S ) without time ordering or ∆ t
نویسنده
چکیده
I derive the expressions for the CP-violating asymmetry arising from interference between mixed and direct decays in the Υ(4S) system, for the case in which only one of the B decay times is observed, integrating over the decay time of the other B. I observe that neither the difference of the decay times ∆t, nor even their time-ordering, need be detected. A technique for measurement of the CP-violating weak decay parameter sin 2β is described which exploits this observation. Typeset using REVTEX

New Time Distributions of D-D̄ or B-B̄ Mixing and CP Violation
The formulae for D0-D̄0 or B0-B̄0 mixing and CP violation at the τ -charm or Bmeson factories are derived, for the case that only the decay-time distribution of one D or B meson is to be measured. In particular, we point out a new possibility to determine the D0-D̄0 mixing rate in semileptonic D decays at the Ψ(4.14) resonance; and show that both direct and indirect CP asymmetries can be measured ...

We present an improved measurement of the standard model CP violation parameter sin 2φ1 (also known as sin 2β) based on a sample of 45 × 10 6 BB pairs collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e− collider. One neutral B meson is reconstructed in a J/ψK0 S , ψ(2S)K 0 S , χc1K 0 S , ηcK 0 S , J/ψK ∗0, or J/ψK0 L CP -eigenstate decay channel and the f...

The Υ(5S) was discovered about 20 years ago in ee collisions at CLEO [1] and CUSB [2]. Its mass is (10865 ± 8) MeV, about 300 MeV higher than the Υ(4S) resonance, and its width of (110± 13) MeV is about five times larger than the Υ(4S) resonance. Its production cross-section was measured to be about 0.3 nb, about ten times lower than the Υ(4S) cross-section. Owing to its mass, the Υ(5S) can dec...
