A Parameterization Invariant Approach to the Statistical Estimation of the CKM Phase $\alpha$

High Energy Physics - Phenomenology 2009-03-31 v2

Abstract

In contrast to previous analyses, we demonstrate a Bayesian approach to the estimation of the CKM phase α\alpha that is invariant to parameterization. We also show that in addition to {\em computing} the marginal posterior in a Bayesian manner, the distribution must also be {\em interpreted} from a subjective Bayesian viewpoint. Doing so gives a very natural interpretation to the distribution. We also comment on the effect of removing information about B00\mathcal{B}^{00}.
