.016 Using the SM ratio gzn/gzl=1.9912+-0.0012 (now need four digits) n_nu = 2.9841+- .0083 Delta Ginv = -2.7-1.5+1.7 MeV, or Delta Ginv < 2.0 MeV (Using Ginv(SM) = 501.7+0.1-0.9 MeV) Strong coupling constant: ========================= With constraint M_T=174.3+-5.1 GeV: alpha_s from Rl = 20.767 +- 0.025 alpha_s = 0.1224 +- 0.0038 (M_H= 100 GeV) alpha_s = 0.1238 +- 0.0038 (M_H= 300 GeV) alpha_s = 0.1257 +- 0.0038 (M_H=1000 GeV) Thus: alpha_s = 0.1224 +- 0.0038 +0.0033-0.000 (M_H= 100+900-0 GeV) alpha_s from s0lep = 2.0003+-0.0027pb: alpha_s = 0.1180 +- 0.0030 (M_H= 100 GeV) alpha_s = 0.1191 +- 0.0030 (M_H= 300 GeV) alpha_s = 0.1206 +- 0.0030 (M_H=1000 GeV) Thus: alpha_s = 0.1180 +- 0.0030 +0.0026-0.000 (M_H= 100+900-0 GeV) The determination of alpha_s from s0lep shows a smaller Higgs- dependence. Also, with the smaller lumi error, s0lep is now 20% more sensitive to alpha_s than Rl. There is a large shift between alpha_s(Rl) and alpha_s(s0lep). This seems to be due to s0had(!) being `off' (also giving us the low number of neutrinos n_nu).

Note that the effect of Weiglein's new fermionic two-loop MW on the chi^2 enters via sin2teff through sin2teff(new)=kappa(old)*(1-MW^2(new)/MZ^2), leading to a large additional TU, rather than through the MW shift itself. Thus the equivalent calculations for sin2teff and for the partial Z widths are needed, as (partial) cancellations in sin2teff(new) = kappa(new)*(1-MW^2(new)/MZ^2) etc. could occur, lowering the TU again.

The one-sided 95%CL (90% two-sided) upper limit on MH is given by TOPAZ0's OU1=N (MH<=195.8 GeV) and ZFITTER's EXPR=1 (MH<=189.2 GeV) ie, combined: MH <= 196 GeV (one-sided 95%CL) -------------------------------- (With the dal5had value of 0.02738+-0.00020 as used in fit 6, the limit is 222 GeV).
