Abstract

A successful connection between Higgs boson decays and the Maximum Entropy Principle is presented. Based on the information theory inference approach we determine the Higgs boson mass as M-H = 125.04 +/- 0.25 GeV, a value fully compatible to the LHC measurement. This is straightforwardly obtained by taking,the Higgs boson branching ratios as the target probability distributions of the inference, without any extra assumptions beyond the Standard Model. Yet, the principle can be a powerful tool in the construction of any model affecting the Higgs sector. We give, as an example, the case where the Higgs boson has an extra invisible decay channel within a Higgs portal model. (C) 2014 Elsevier B.V. All rights reserved. (AU)
