LEP EW WG Plots for the Winter 2002 Conferences
Latest modifications as of February 26th, 2002.
You can find here the plots that have been produced for the Winter
2002 conferences. Some plots may show up here in a couple of
slightly different presentations, depending on who has made the plot.
They all use the same data. Many results and plots are still based on
preliminary results.
Note that essentially the full set of plots will be made available,
including those that have data that hasn't changed, so that "one-stop
shopping" can be done.
Answers to FAQs on plots presented below:
- Afb_q and R_q[=GZ_q/GZ_had] bar-chart plots for heavy quark flavours
comparing ADLOS results:
- In contrast to previous versions of these plots for older
conferences, all numerical values as well as all dots with
error bars are so-called pole quantities, eg, Afb0q, and in
particular corrected to exactly the same set of values for
other parameters. When applicable, the measurements at the
off-peak energy are transported to the peak and included
in the results.
- Thus the results shown are directly comparable, among
themselves as well as with the average, but do not
neccessarily correspond digit-by-digit to the numerical
values found in the individual experimental publications.
- Epsilon-parameter contour
- Based on a fit varying alpha(dal5had), alpha_s, MZ, and the
four epsilon_123b parameters
- Data set consists of all measurements except Gamma_W, M_top
and sin2theta from NUTEV due to its explicit M_top/M_Higgs
dependence (M_top/M_Higgs cannot be expressed in terms of the
four epsilon parameters). APV is also not included, as
additional model assumptions are needed to express APV in
terms of the epsilon parameters.
- STU-parameter contour
- Based on a fit varying alpha(dal5had), alpha_s, MZ, and the
three STgamma_b parameters
- U=0 fixed throughout
- Data set consists of all measurements except Gamma_W, M_top
and sin2theta from NUTEV due to its explicit M_top/M_Higgs
dependence (M_top/M_Higgs cannot be expressed in terms of the
four STUgamma_b parameters). APV is also not included, as
additional model assumptions are needed to express APV in
terms of the STUgamma_b parameters.
- The additional bands correspond to +-1sigma bands for the
alpha_s independent quantities
GZ_lepton, MW and sin2teff (in order of increasing
slope dT/dS). GZ_lepton instead of GZ_tot is chosen because
the latter depends in addition on alpha_s and the former
exhibits a more extreme (ie, flatter) slope.
All other fit parameters are fixed.
- The MSM reference values (STUgamma_b=0) are dal5had=0.02761,
alpha_s=0.118, MZ=91.1875 GeV, M_top=175 GeV, M_Higgs=150 GeV
- Higgs constraint from each measurement:
- For each observable, the corresponding constraint on the
Higgs mass is determined in a full MSM fit to the measurement
result of this observable, constraining
dal5had=0.02761+-0.00036, alpha_s=0.118+-0.002, MZ =
91.1875+-0.0021 GeV and M_top=174.3+-5.1 GeV.
- For Higgs masses larger than about 1 TeV, the MSM and its
formulae used do not make too much sense, so that part of
the Higgs mass regime shown in the plot should not be taken
quantitatively.
Enjoy!
