Measurement of the lifetime difference in the Bs0 system
We present a study of the decay Bs0â†'J/ÏÏ•. We obtain the CP-odd fraction in the final state at time zero, R⚥=0.16±0.10(stat)±0.02(syst), the average lifetime of the (Bs0, BÂs0) system, Ï.,Â(Bs0)=1.39- 0.16+0.13(stat)-0.02+0.01(syst)ps, and the relative width difference between the heavy a...

| description | We present a study of the decay Bs0â†'J/ÏÏ•. We obtain the CP-odd fraction in the final state at time zero, R⚥=0.16±0.10(stat)±0.02(syst), the average lifetime of the (Bs0, BÂs0) system, Ï.,Â(Bs0)=1.39- 0.16+0.13(stat)-0.02+0.01(syst)ps, and the relative width difference between the heavy and light mass eigenstates, Î"Î"/ Î"Â≡(Î"L-Î"H)/ Î"Â=0.24-0.38+0.28(stat)-0.04+0.03(syst). With the additional constraint from the world average of the Bs0 lifetime measurements using semileptonic decays, we find Ï.,Â(Bs0)=1.39±0.06ps and Î"Î"/Î"Â=0.25-0.15+0.14. For the ratio of the Bs0 and B0 lifetimes we obtain Ï.,Â(Bs0)Ï.,(B0)=0. 91±0.09(stat)±0.003(syst). © 2005 The American Physical Society. |
