==================================================================== Lifetime and mixing results not included in the Summer 2004 averages ==================================================================== O. Schneider December 29, 2004 The lifetime and mixing results listed below have not been included in the HFAG averages presented in hep-ex/0412073. The plan is to include them in the next round of averages. ------------ B0 lifetime: ------------ ===> 1.539 +-0.051 +- 0.008 ps CDF2 prel, CDF note 7409 (2004), excl. J/psi K, will supersede a preliminary result shown in Aachen (2003) 1.49 +- 0.06 +- 0.062 ps. ===> 1.501 +-0.008 +-0.030 ps BABAR, BABAR-CONF-04/15, ICHEP04, incl. D*l, measured simultaneously with dmd ===> 1.534 +-0.008 +-0.010 ps Belle, hep-ex/0408111, subm. to PRD, measured simultaneously with dmd and B+ lifetime, will supersede another measurement already included in the average ------------ B+ lifetime: ------------ ===> 1.662 +-0.033 +- 0.008 ps CDF2 prel, CDF note 7409 (2004), excl.
