Search for exclusive decays of the Lambda(b) baryon and measurement of

Περίληψη:
A search for fully reconstructed Lambda(b)(0) beauty baryons is
performed using about 3 million Z decays collected with the DELPHI
detector at LEP. The analysis relies on the combined use of the accurate
tracking and of the hadron identification capabilities of DELPHI. A
total of four events has been found, three in the Lambda(c)(+)pi(-)
channel and one in the Lambda(c)(+)a(1)(-) channel over a small
background. The Lambda(b)(0) beauty baryon mass is measured to be (5668
+/- 16 (stat.) +/-8 (syst.)) MeV/c(2).
