Least-informative priors for 0νββ decay searches
Least-informative priors for 0νββ decay searches
Bayesian parameter inference techniques require a choice of prior distribution, which can stronglyimpact the statistical conclusions drawn. We discuss the construction of least-informative priors forneutrinoless double beta decay searches. Such priors attempt to be objective by maximizing the informationgain from an experimental setup. In a parametrization using the lightest neutrino mass ml and an effective Majorana phase parameter Φ, we construct such a prior using two different approaches and compare themwith the standard flat and logarithmic priors in ml.

Abstract
Bayesian parameter inference techniques require a choice of prior distribution, which can stronglyimpact the statistical conclusions drawn. We discuss the construction of least-informative priors forneutrinoless double beta decay searches. Such priors attempt to be objective by maximizing the informationgain from an experimental setup. In a parametrization using the lightest neutrino mass ml and an effective Majorana phase parameter Φ, we construct such a prior using two different approaches and compare themwith the standard flat and logarithmic priors in ml.
