Book Description
We report the measurement of the lifetime of the D° meson. The direct observation of the decay vertex distribution in the process D° .-->. K−.pi. was made using a vertex chamber installed in the HRS detector at PEP. The measured lifetime is found to be tau/sub D°/ = .42 +- 09 +- 06ps. 5 refs., 4 figs.

Book Description
The lifetime of the B[sub s][sup 0] meson is measured using the semileptonic decay B[sub s][sup 0][r-arrow] D[sub s][sup[minus]]l[sup[plus]][nu]X. The data sample consists of approximately 110 pb[sup[minus]1] of p[ovr p] collisions at[radical]s= 1.8 TeV collected by the CDF detector at the Fermilab Tevatron collider. There are 254[plus-minus]21 D[sub s][sup[minus]]l[sup[plus]] signal events where the D[sub s][sup[plus]] is reconstructed through its decay mode D[sub s][sup[minus]][r-arrow][phi][pi][sup[minus]], [phi][r-arrow] K[sup[plus]]K[sup[minus]]. Using these events, the B[sub s][sup 0] meson lifetime is determined to be[tau](B[sub s][sup 0])[equals] 1.37[sup[plus]0.14][sub[minus]0.12](stat.)[plus-minus]0.04(syst.) ps. The B[sub s][sup 0] meson proper decay length distribution has been examined for a lifetime difference between the two CP eigenstates of the B[sub s][sup 0] meson, B[sub s][sup H] and B[sub s][sup L]. 12 refs., 3 figs., 1 tab.

Book Description
The neutral B meson lifetime has been measured with the data collected by the BABAR detector at the PEP-II storage ring during the year 2000 for a total integrated luminosity of 20.3 fb[sup -1]. The B[sup 0][yields] D*[sup -][pi][sup+] decays have been selected with a partial reconstruction method in which only the fast pion from the B[sup 0] decay and the slow pion from D*[sup -][yields][bar D][sup 0][pi][sup -] are reconstructed. The B[sup 0] lifetime has been measured to be 1.510[+-] 0.040[+-] 0.038 ps with a sample of 6971[+-] 241 reconstructed signal events.

Book Description
The neutral B meson lifetime is measured with the data collected by the BABAR detector at the PEP-II storage ring during the years 1999 and 2000, with a total integrated luminosity of 20.7 fb[sup -1]. The decays B[sup 0][yields] D*[sup -][pi][sup+] and B[sup 0][yields] D*[sup -][rho][sup+] are selected with a partial-reconstruction technique, yielding samples of 6970[+-] 240 and 5520[+-] 250 signal events, respectively. With these events, the B[sup 0] lifetime is measured to be 1.533[+-] 0.034 (stat.)[+-] 0.038 (syst.) ps. This measurement serves as a test and validation of procedures required to measure the CP violation parameter sin (2[beta]+[gamma]) with partial reconstruction of these modes.
