Higgs' Mass Plot by Technique. The yellow region is excluded
by direct searches for the Higgs by the LEP experiments. The curves represent probability distributions for what the
Higgs mass should be based on several different experimental techniques. The minimum
of the curves is the most likely Higgs mass and where the curves intersect the 95% CL or
99% CL lines indicate that the Higgs mass should be below that intersection point with 95%
or 99% confidence, respectively. SLD's result is shown in red. The CERN result
using leptonic asymmetries is shown in blue. Combined results from W mass measurements at
CERN and Fermilab are shown in green. The black band labeled 'Other'
includes LEP measurements of G_{Z}, s_{had}^{0},
and R_{l}, LEP/SLD measurements of R_{b} and R_{c},
SLD measurements of A_{b} and A_{c}, and NuTeV's measurement
of R^{}. All these techniques are selfconsistent and prefer a light Higgs
mass. But the CERN result from the hadronic measurement of the weak mixing angle,
which uses the forwardbackward asymmetry in decays of the Z^{0 }to b quarks
(shown in magenta), favors a much heavier Higgs. (This plot is made using Da_{had}(M_{Z}^{2})=0.02738 +/ 0.00020.)

Higgs' Mass Plot comparing the LEP A_{FB}^{b}
measurement with the rest of the world's data.. Combining
all the world's data, but excluding the LEP A_{FB}^{b}
result, yields the curve shown in red and determines that the Higgs
should be lighter than 190 GeV at 99% CL. The magenta curve shows the
forwardbackward bquark asymmetry result from LEP. In
this case, one finds that the Higgs should be heavier than 190 GeV at 99%
CL!
