Inferring $\rhobar$ and $\etabar$ of the CKM matrix - A simplified, intuitive approach

Abstract

This analysis is based on the same ideas and numerical inputs of the recent paper by Ciuchini et al. on the subject. Some approximations are applied, which make analytical calculations applicable in most of the work, thus avoiding Monte Carlo integration. The final result is practically identical to the one obtained by the more detailed numerical analysis.
