We present here the first measurement of the B[sup 0] lifetime using partial reconstruction in B[sup 0] [yields] D*[sup -] [rho][sup +] decay. A sample of appro

The two B[sup 0] decay processes B[sup 0][yields] D*[sup -][pi][sup+] and B[sup 0][yields] D*[sup -][ell][sup+][nu][sub[ell]] have been studied by means of a pa

A sample of about 5500 {bar B}° → D*?− and 700 {bar B}° → D*+a1− events is identified, using the technique of partial reconstruction, among 22.7 milli
