A MEASUREMENT OF THE MEAN LIFETIMES OF CHARGED AND NEUTRAL B-HADRONS
Γλώσσες Τεκμηρίου:

Περίληψη:
The decays of B-hadrons have been reconstructed using the charged
particles recorded in the DELPHI silicon microstrip detector. The sum of
the charges of the secondaries determines the charge of the B-hadron
parent. Some 232 114 multihadronic Z0 decays recorded during the 1991
run of LEP at centre-of-mass energies between 88.2 GeV and 94.2 GeV
yield 253 B-hadron candidates with well-measured charge. From these the
mean lifetimes of neutral and charged B-hadrons are found to be 1.44 +/-
0.21(stat.) +/- 0.14(syst.) ps and 1.56 +/- 0.19(stat.) +/- 0.13(syst.)
ps respectively. The ratio of their lifetimes is 1.09(-0.23)+0.28
(Stat.) +/- 0.11 (syst.). Under some assumptions on the abundance and
lifetime of the LAMBDA(b)0 and B(s)0 states, the B0 and B+ lifetimes are
inferred.
