Tevatron Run 2 SUSY/Higgs Workshop Final Higgs Results
Last update: 25 August 2000 by John Conway
Collected here are the final combined results from the
Higgs Working Group
of the Tevatron
Run 2 SUSY/Higgs workshop. These are the basis of the
results published in the final report (hep-ph/0010338).
We have adopted the Bayesian combination method described here for the combination. In short, the
statistical thresholds are based on calculating the joint likelihood
for having observed a given experimental outcome, as a function of the
Higgs production cross section.
In the cases indicated, a nominal systematic error has been assumed on
the background normalization only. This error is taken to be equal to
the statistical error, 1/sqrt(LB), where L is the integrated
luminosity and B is the expected background in 1 inverse fb. The
error can be a maximum of 10%. Only error on the background is
incorporated, because including errors both on signal and background
is prohibitive from the standpoint of computing time.
Tables with the input numbers for each channel can be found
here for the low- and high-mass channels.
All the low-mass results are based on the assumption of a 10%
mass resolution. We have results for CDF extrapolated, SHW,
and neural net analyses. The complete writeup should be consulted
for details of the calculations.
Plots of the discovery and exclusion reach in the MSSM can be found
at Steve Mrenna's page.
- SM Higgs integrated luminosity thresholds, 90-200 GeV Higgs mass
CDF-based low-mass analyses (Yao, et al.) plus high-mass SHW analyses:
SHW-based low-mass analyses (Barberis, Jesik, et al.) plus high-mass SHW analyses:
Neural network analysis (Bhat et al.) plus high-mass channels:
Neural network analysis (Bhat et al., June 1999), with vvbb background
doubled, plus high-mass channels. Unfortunately this is NOT the
final result, though it was shown as such for over a year. See the
next group of links...
Neural network analysis (Bhat et al., December 1999), with vvbb background
doubled, plus high-mass channels. No high-mass trilepton channel used:
This IS the final, ultimate, last ever combined result! Really!
- R plots, VH, H -> bb channels (low mass) only (all with systematic errors except
as noted)
