Measurement of the branching fractions of semileptonic kaon decays and extraction of the CKM parameter |Vus|

open access: yes, 2017
Semileptonic kaon decays (Kl3 = K^+ → π^0 l^+ ν with l = e, μ) provide a clean way to extract the parameter |Vus| of the Cabibbo-Kobayashi-Maskawa (CKM) quark mixing matrix. It is one of the fundamental parameters of the Standard Model and is only accessible via experimental measurement. The NA62 collaboration collected K^+ decay data in 2007 which are

The CKM Wolfenstein Parameters from Generative Triple Evolution Orbit Arithmetic

open access: yes
We derive all four Wolfenstein parameters of the CKM quark mixing matrix from the arithmetic of the Rule~110 cellular automaton orbit that the Standard Model generation sequence is forced to satisfy~, with zero free parameters. The derivation proceeds in two stages.

Renormalization invariants and the CKM matrix

open access: yes, 2009
In this research work, we introduce a rephrasing invariant parameterization of the CKM matrix, which is parameterized in terms of six manifestly rephrasing invariant parameters, and they exhibit explicitly hierarchies in power of λ 2, from zero order ...

A Parameter-Free Relation Between Quark Mass Ratios and CKM Mixing Angles

open access: yes
We document a numerical regularity in PDG data: the three mixing angles of the CKMmatrix are approximately given by sin θij =pmi/mj , extending the historical Gatto-SartoriTonin(1968) relation for the Cabibbo angle to all three angles. Evaluated in the space ofpossible combinatorial configurations (C(15, 3) = 455 triplets of pairs), this ...
