Determination of the Average Lifetime of Bottom Hadrons

We have determined the average lifetime of hadrons containing b quarks produced in e + e − annihilation to be τ B = 1.83 +0.83 +0.37 − −0.34 ×10 −12 s . Our method uses charged decay products from both non-leptonic and semileptonic decay modes.
