CKM elements from tree-level b decays and lifetimes

open access: yes, 2003
This report contains the results of the Workshop on the CKM Unitarity Triangle, held at CERN on 13-16 February 2002 to study the determination of the CKM matrix from the available data of K, D, and B physics.

CKM Gene rs8111989 Polymorphism and Power Athlete Status. [PDF]

open access: yes, 2021
Multiple genetic variants are known to influence athletic performance. These include polymorphisms of the muscle-specific creatine kinase (CKM) gene, which have been associated with endurance and/or power phenotypes.

Flavor physics in the quark sector [PDF]

open access: yes, 2008
In the past decade, one of the major challenges of particle physics has been to gain an in-depth understanding of the role of quark flavor. In this time frame, measurements and the theoretical interpretation of their results have advanced tremendously. A

Prospects of CKM parameter measurements at Belle II [PDF]

open access: yesProceedings of The European Physical Society Conference on High Energy Physics — PoS(EPS-HEP2017), 2018
Semileptonic and leptonic $B$ decays are powerful probes to search for physics beyond the Standard Model (SM) as they can be calculated in the SM with high precision. We report recent results on rare $B$ decays with leptons from the Belle experiment at the KEKB $e^+e^−$ collider.

A Determination of the CKM Parameter |Vus|

open access: yes, 2004
We present a determination of the CKM parameter |Vus| based on new measurements of the six largest KL branching fractions and semileptonic form factors by the KTeV (E832) experiment at Fermilab. We find |Vus| = 0.2252 +- 0.0008(KTeV) +- 0.0021(ext), where the errors are from KTeV measurements and from external sources.

Time-dependent angular analysis of the decay Bs -> J/psi phi and extraction of Delta Gamma_s and the CP-violating weak phase phi_s by ATLAS [PDF]

open access: yes, 2012
A measurement of Bs J/psi phi decay parameters, including the CP-violating weak phase phi_s and the decay width difference Delta Gamma_s is reported, using 4.9 fb-1 of integrated luminosity collected in 2011 by the ATLAS detector from LHC pp collisions ...

New determination of the D0→K -π +π0 and D0→K -π +π +π - coherence factors and average strong-phase d [PDF]

open access: yes, 2014
Measurements of the coherence factors (RKππ0 and R K3π) and the average strong-phase differences (δDKππ0 and δDK3π) for the decays D0→K -π +π0 and D0→K -π +π +π - are presented.

On the statistical treatment of the Cabibbo angle anomaly

open access: yesJournal of High Energy Physics, 2020
We point out that testing the equality of the Cabibbo angle as extracted from Γ(K → πlν), the ratio Γ(K → lν)/Γ(π → lν) and nuclear β decays is not identical to a test of first row unitarity of the Cabibbo-Kobayashi-Maskawa (CKM) matrix.
