Determining the CKM Parameter Vcd from nuN Charm Production

open access: yes, 1997
The formalism for extracting the CKM parameter $V_{cd}$ from $ N$ production of charm is discussed in some detail. The various model assumptions needed are clearly pointed out. A direct determination from neutrino induced dimuon production requires $ N$ charm production data, $% N$ charm hadronization data, and the semi-muonic branching ratios for ...

The q 2 moments in inclusive semileptonic B decays

open access: yesJournal of High Energy Physics
We compute the first moments of the q 2 distribution in inclusive semileptonic B decays as functions of the lower cut on q 2, confirming a number of results given in the literature and adding the O α s 2 β 0 $$ O\left({\alpha}_s^2{\beta}_0\right) $$ BLM ...

Vacuum Induced CP Violation Generating a Complex CKM Matrix with Controlled Scalar FCNC

open access: yes, 2018
We propose a viable minimal model with spontaneous CP violation in the framework of a Two Higgs Doublet Model. The model is based on a generalised Branco-Grimus-Lavoura model with a flavoured $\mathbb{Z}_2$ symmetry, under which two of the quark families

Quark-hadron duality violations and higher-order 1/m b corrections in inclusive semileptonic B decays

open access: yesJournal of High Energy Physics
The theoretical description and data for inclusive semileptonic B decays have reached incredible precision. This motivated us to re-animate the discussion of possible Quark-Hadron Duality violations.

Renormalization Group Equations for the CKM matrix

open access: yes, 2008
We derive the one loop renormalization group equations for the Cabibbo-Kobayashi-Maskawa matrix for the Standard Model, its two Higgs extension and the minimal supersymmetric extension in a novel way.

Testing the CKM parameters with parity violating longitudinal muon polarization in K+ → π+μ+μ−

open access: yesNuclear Physics B, 1993
We point out that the parity violating longitudinal muon polarization PL in the decay K+→π+μ+μ− is closely related to the short-distance part of the decay amplitude in KL → μ+μ−. M Measuring such polarization would provide not only a rather clean test on the CKM parameter ϱ, but also a check on the short-distance contribution to KL → μ+μ−. The possible

New physics searches via angular distributions of B ¯ → D ∗ → Dπ τ → ℓ ν τ ν ¯ ℓ ν ¯ τ $$ \overline{B}\to {D}^{\ast}\left(\to D\pi \right)\tau \left(\to \ell {\nu}_{\tau }{\overline{\nu}}_{\ell}\right){\overline{\nu}}_{\tau } $$ decays

open access: yesJournal of High Energy Physics
The study of B ¯ → D ∗ τ ν ¯ τ $$ \overline{B}\to {D}^{\ast}\tau {\overline{\nu}}_{\tau } $$ angular distribution can be used to obtain information about new physics (or beyond the Standard Model) couplings, which are motivated by various B anomalies ...
