Averaging lifetimes for B hadron species

1996 
The measurement of the lifetimes of the individual B species are of great interest. Many of these measurements are well below the 10 % level of precision. However, in order to reach the precision necessary to test the current theoretical predictions, the results from different experiments need to be averaged. Therefore, the relevant systematic uncertainties of each measurement need to be well defined in order to understand the correla­ tions between the results from different experiments. In this paper we discuss the dominant sources of systematic errors which lead to correlations between the different measurements. We point out problems connected with the conventional approach of combining lifetime data and discuss methods which overcome these problems. 1) Dipartimento di Fisica Universita' di Roma II, 00173 Rome, Italy. 2) CERN, 1211 Geneva 23, Switzerland. 3) Department of Physics, University of Oxford, Oxford, OX1 3RB, UK. 4) Max Planck Institut fur Physik, 80805 Munchen, Germany. 5) Centre for Research in Particle Physics, Carleton University, Ottawa, Ontario K1S 5B6, Canada. tnow at Universite de Geneve, 1211 Geneva 4, Switzerland. tnow at Universitat Hamburg/DESY, 22603 Hamburg, Germany;>
