| 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 160–170 GeV, with an expectation uncertainty,
quantified by the standard deviation of the distribution, of about 60–80 GeV. The median of the distribution is 150 GeV, while
75% of the probability is concentrated in the region GeV. The 95% probability upper limit turns out to be around 300 GeV.
