The entropy of the Higgs boson decay probabilities distribution in the Standard Model (SM) is maximized for a Higgs mass value that is less than one standard deviation away from the current experimental measurement. This successful estimate of the Higgs mass encourages us to propose tests of the Maximum Entropy Principle (MEP) as a tool for theoretical inferences in other instances of Higgs physics. In this letter, we show that, irrespective of the extension of the SM predicting a new Higgs boson decay channel, its branching ratio can be inferred to be around 7% in such a way that the new entropy of decays still exhibits a maximum at the experimental Higgs mass. This 7% rule can be tested whenever a new Higgs decay channel is found. In order to illustrate the MEP predictions, we apply the MEP inference to Higgs portal models, Higgs-axion interactions, lepton flavor violating decays of the Higgs boson, and a dark gauge boson model.

7%法则:关于希格斯玻色子新衰变的最大熵预测

对于希格斯质量值而言,标准模型(SM)中希格斯玻色子衰变概率分布的熵最大化,该值小于当前实验测量值的一个标准偏差。希格斯质量的这一成功估计鼓励我们提出对最大熵原理(MEP)的测试,作为在希格斯物理学的其他情况下进行理论推论的工具。在这封信中,我们表明,不管SM的扩展预测新的希格斯玻色子衰变通道,其分支比都可以推断为7%左右,这样新的衰变熵仍会在实验希格斯质量。每当发现新的希格斯衰减通道时,都可以测试此7%规则。为了说明MEP预测,我们将MEP推论应用于希格斯门户网站模型,
