Light quark loops in K ± → π ± ν ν ¯ $$ {K}^{\pm}\to {\pi}^{\pm}\nu \overline{\nu} $$ from vector meson dominance and update on the Kaon Unitarity Triangle

open access: yesJournal of High Energy Physics
We use vector meson dominance to calculate non-perturbative contributions to the branching ratio of the rare decay K ± → π ± ν ν ¯ $$ {K}^{\pm}\to {\pi}^{\pm}\nu \overline{\nu} $$ stemming from matrix elements involving up-quark loops.

Unitarity of CKM Matrix [PDF]

open access: yes, 2002
The Unitarity of the CKM matrix is examined in the light of the latest available accurate data. The analysis shows that a conclusive result cannot be derived at present.

APOSCREEN-1 – a prospective, single-arm clinical trial for the implementation of a pharmacy-based screening for cardiovascular-kidney-metabolic risk factors in Schleswig-Holstein

open access: yesBMC Nephrology
Background Cardiovascular-kidney-metabolic (CKM) syndrome has emerged as a major global health burden and driver of cardiovascular disease (CVD), the leading cause of death worldwide.

Unitarity triangle angles explained: a predictive new quark mass matrix texture

open access: yesJournal of High Energy Physics
We propose a novel quark mass matrix texture-pair with five free parameters, which fits the four quark mass ratios m s /m b , m d /m b , m c /m t , m u /m t , and the four CKM quark mixing observables.

Precision measurements of the CKM angle gamma

open access: yes, 2016
The level of CP-violation permitted within the Standard Model cannot account for the matter dominated universe in which we live. Within the Standard Model the CKM matrix, which describes the quark couplings, is expected to be unitary.

Relationships between Quark Masses and the CKM Elements

open access: yes, 1997
There are mysteries that the origin of small values in the Cabibbo-KobayashiMaskawa (CKM) matrix and the reason why the CKM matrix is close the unit matrix. We use the general quark mass matrices in order to solve the these problems.

SLAC-PUB-15659 CKM angles and sides from BABAR

open access: yes, 2014
on behalf of the BABAR Collaboration Abstract. The CKM paradigm has been proven to be successful in explaining the flavour structure of the standard model and the non-trivial imaginary phase of the CKM matrix is the only know source of CP-violation.
