摘要：

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 M-H less than or equal to 200 GeV. The 95% probability upper limit turns out to be around 300 GeV.
