Measurement of the (B)over-bar lifetime and the B-0(B)over-bar(0) oscillation frequency using partially reconstructed (B)over-bar(0)-> D*+ l-(v)over-bar(l) decays
B. Aubert, R Barate, D Boutigny, F. Couderc et autres
We present a simultaneous measurement of the (B) over bar (0) lifetime tau(B0) and B-0(B) over bar (0) oscillation frequency Delta m(d). We use a sample of about 50 000 partially reconstructed (B) over bar (0)-> D(*+)l(-)nu(l) decays identified with the BABAR …
