Query: A Statistical Analysis for the Neutrinoless Double-Beta Decay Matrix
  element of 48Ca   Neutrinoless double beta decay ($0\nu\beta\beta$) nuclear matrix elements
(NME) are the object of many theoretical calculation methods, and are very
important for analysis and guidance of a large number of experimental efforts.
However, there are large discrepancies between the NME values provided by
different methods. In this paper we propose a statistical analysis of the
$^{48}$Ca $0\nu\beta\beta$ NME using the interacting shell model, emphasizing
the range of the NME probable values and its correlations with observables that
can be obtained from the existing nuclear data. Based on this statistical
analysis with three independent effective Hamiltonians we propose a common
probability distribution function for the $0\nu\beta\beta$ NME, which has a
range of (0.45 - 0.95) at 90\% confidence level of, and a mean value of 0.68.
