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.
