2009-03-13: Winter 2009 ======================= Contact: Martin.Grunewald@cern.ch Winter 2009: Changes in experimental inputs w.r.t. summer 2008 * New Tevatron Mtop (preliminary, March 2009) Summer 2008: Changes in experimental inputs w.r.t. winter 2008 * New Tevatron Mtop (preliminary, July 2008) * New Tevatron MW and GW averages * Hence new world averages for MW and GW Winter 2008: Changes in experimental inputs w.r.t. winter 2007 * New Tevatron Mtop (preliminary, Mar. 2008) * New Tevatron MW and GW averages * Hence new world averages for MW and GW Winter 2007: Changes in experimental inputs w.r.t. summer 2006 * New Tevatron Mtop (preliminary, Mar. 2007) * New Tevatron MW (preliminary, CDF Run-II, Jan. 2007) * Hence new world averages for MW and GW Summer 2006: Changes in experimental inputs w.r.t. winter 2006 * New Tevatron Mtop * New LEP-2 MW and GW combination (ADLO final, but combination preliminary) * Hence new world averages for MW and GW Winter 2006: Changes in experimental inputs w.r.t. summer 2005 * New Tevatron Mtop * New Tevatron GW * New LEP-2 MW and GW combination (ALO final) * Hence new world averages for MW and GW Summer 2005: Changes in experimental inputs w.r.t. z-pole 2005 * New Tevatron Mtop (not just LP05 but EPS05 value!) * New LEP-2 (and thus world) MW and GW combination (OPAL final!) Z-pole 2005: Changes in experimental inputs w.r.t. winter 2005 * Change in gamma_b of STU fit due to re-definition of gamma_b. * Really final Z-pole HF combination * New dal5had hadronic vacuum polarisation * New ZFITTER 6.42 Note: Now all LEP+SLD Z-pole results are really final!

TU) ----------------------------------------- (increasing to 191 GeV when including the LEP-2 direct search limit). EOF
