How well do we know the Unitarity Triangle? An experimental review

TL;DR

This paper reviews the progress over the past decade in measuring the parameters of the CKM matrix, highlighting how these measurements enhance our understanding of CP violation within the Standard Model and potential new physics.

Contribution

It provides a comprehensive review of experimental measurements of the CKM parameters rho and eta and discusses their implications for CP violation and the unitarity triangle.

Findings

Significant improvement in CKM parameter measurements over 10 years

Enhanced understanding of CP violation in the Standard Model

Implications for physics beyond the Standard Model

Abstract

In the past 10 years our knowledge of the parameters rho and eta of the Cabibbo-Kobayashi-Maskawa matrix has improved substantially. This article reviews the measurements that contributed to this advance, and discusses their implication in terms of understanding CP violation in the Standard Model and beyond.
