چکیده
If the unitary quarkmixing matrix, V , is moduli symmetric then it depends on three real parameters. This means that there is a relation between the four parameters needed to parametrize a general V . It is shown that there exists a very simple relation involving |V11|, |V33|, ρ and η. This relation is compared with the present experimental data. It is concluded that a moduli symmetric V is not ruled out. [email protected] [email protected]

A self-consistent analysis of K → 2π and K → 3π decays within a unique framework of chiral dynamics applied to the QCD-corrected weak nonleptonic quark lagrangian has been performed. The results on K → 2π amplitudes at O(p), including the value for ε ′ /ε, are compared with experiment to fix phenomenological B-factors for mesonic matrix elements of nonpenguin and penguin four-quark operators. T...

In a scenario where the constituent quarks are composite systems, Generalized Parton Distributions (GPDs) are built from wave functions to be evaluated in a Constituent Quark Model (CQM), convoluted with the GPDs of the constituent quarks themselves. The approach permits to access the full kinematical range corresponding to the DGLAP and ERBL regions, so that cross sections for deeply virtual C...

In the Standard Model of elementary particles, quark-mixing is expressed in terms of a 3 x 3 unitary matrix V , the so called Cabibbo-Kobayashi-Maskawa (CKM) matrix. Significant unitarity checks are so far possible for the first row of this matrix. This article reviews the experimental and theoretical information on these matrix elements. On the experimental side, we find a 2.2 σ to 2.7 σ devia...

We clarify the nonperturbative origin of the δ-function singularity at x = 0 in the chiral-odd twist-3 distribution function e(x) of the nucleon. We also compare a theoretical prediction for e(x) based on the chiral quark soliton model with the empirical information extracted from the CLAS semi-inclusive DIS measurement.
