Abstract
We combine, within the framework of the standard model,
the results of Higgs search experiments with the information
coming from an accurate theoretical calculation and precision
measurements
to
provide a probability density function for the Higgs mass,
from which all numbers of interest can be
derived. The expected value is around
160-170GeV, with an expectation uncertainty, quantified
by the standard deviation of the distribution, of about 60-80GeV.
The median of the distribution is 150GeV, while 75%
of the probability is concentrated in the region 
GeV.
The 95% probability upper limit turns out to be around 300GeV.
