It provides a comprehensive overview of theoretical issues and alternative methods for determining |Vub|, and discusses future directions in flavor physics research.

Findings

Identification of theory shortcomings in unitarity triangle analysis

Proposal of alternative methods for |Vub| determination

Discussion on the scale of Minimal Flavor Violating interactions

Abstract

We first review some aspects of the determination of the sides and angles of the unitarity triangle. We pay particular attention to theory shortcomings, and present many alternative proposals for the determination of |Vub| (which at present is problematic). We then turn our attention to the more general question: What have we learned so far about flavor physics and where do we go from here? We argue that the aim of Flavor Physics should be to establish or rule out Minimal Flavor Violating interactions up to a scale of 10 TeV.
