Quark mixing and CP violation - the CKM matrix

open access: yes, 2005
I present the status of the elements and parameters of the Cabibbo-Kobayashi-Maskawa (CKM) matrix and summarise the related theoretical progress since "Lepton-Photon 2003". One finds |V_{us}| = 0.2227 +/- 0.0017 from K and tau decays and |V_{cb}| = (41.6

Top-quark flavor-changing $tqZ$ couplings and rare $\Delta F=1$ processes

open access: yes, 2019
We model-independently study the impacts of anomalous $tqZ$ couplings ($q=u,c$), which lead to the $t\to q Z$ decays, on low energy flavor physics. It is found that the $tuZ$-coupling effect can significantly affect the rare $K$ and $B$ decays, whereas ...

Lattice Matrix Elements and CP Violation in B and K Physics: Status and Outlook

open access: yes, 2003
Status of lattice calculations of hadron matrix elements along with CP violation in B and in K systems is reviewed. Lattice has provided useful input which, in conjunction with experimenatl data, leads to the conclusion that CP-odd phase in the CKM ...

Value of tax shields and the risk of the net increase of debt, The. Year 2004 [PDF]

open access: yes
The value of tax shields depends on the nature of the stochastic process of the net increase of debt; it does not depend on the nature of the stochastic process of the free cash flow.

Reply to "The value of tax shields is equal to the present value of tax shields" [PDF]

open access: yes
In a recent paper, Cooper and Nyborg (2004) argue that the results of Fernández (2004) are wrong because value-additivity is violated and because "Fernández paper comes from mixing the Miles-Ezzell leverage policy with the Miller-Modigliani leverage ...

Sensitivity of Helioseismic Measurements of Normal-mode Coupling to Flows and Sound-speed Perturbations

open access: yes, 2017
In this article, we derive and compute the sensitivity of measurements of coupling between normal modes of oscillation in the Sun to underlying flows.

B_d and B_s mixing: mass and width differences and CP violation

open access: yes, 2007
B-B-bar mixing involves three physical parameters: the magnitudes of the off-diagonal elements of the mass and decay matrices and their relative phase.

Flavour from the Planck scale to the electroweak scale

open access: yes, 2019
We discuss a theory of flavour in which Higgs Yukawa couplings are related to those of the new scalar triplet leptoquark and/or $Z'$ responsible for $R_{K^{(*)}}$, with all couplings arising effectively from mixing with a vector-like fourth family, whose
