Measurement of the lifetime difference in the Bs0 system

Journal article

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 deca...
