CKM elements from tree-level b decays and lifetimes
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.

A Determination of the CKM Parameter |Vus|
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.

Prospects of CKM parameter measurements at Belle II [PDF]
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.

New determination of |V ub /V cb | from B s 0 $$ {B}_s^0 $$ → {K − , D s − $$ {D}_s^{-} $$ }μ + ν
We update the full set of B ¯ $$ \overline{B} $$ s → K form factors using light-cone sum rules with an on-shell kaon. Our approach determines the relevant sum rule parameters — the duality thresholds — from a Bayesian fit for the first time.

On the statistical treatment of the Cabibbo angle anomaly
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.

Hypertension in obesity represents a major global health challenge, closely linked to the global epidemics of obesity, type 2 diabetes and metabolic dysfunction. Excess adiposity contributes to elevated blood pressure through multiple, interrelated mechanisms, including activation of the renin–angiotensin–aldosterone system, sympathetic nervous system ...
