摘要: I discuss findings from my recent comparison of Bayesian and frequentist approaches to resonance searches ([1902.03243][1]). I introduce a counting experiment based on a search for the Higgs boson from which I generate pseudo-data. With that pseudo-data, I contrast the evolution of the $p$-value and posterior as we accumulate data and directly compare global p-values and the posterior of the background model. I find that in this toy problem p-values are typically smaller than the posterior by one or two orders of magnitude. I discuss the implications of this result for our interpretation of anomalies in resonance searches and searches for new physics in general.
