[en] Five different hyperon semileptonic decays have been made by the WA2 experiment. The results are summarized. The WA2 collaboration have performed a Cabibbo fit using only one datum not from the WA2 experiment. The fit gives a Λ²/df of 4.5/5. Other fits are mentioned. (U.K.)

[en] Full text of publication follows: The T2K long baseline experiment located in Japan is dedicated mainly to constrain or measure the theta neutrino mixing angle by searching for the electron neutrino appearance in Super-Kamiokande in a pure muon neutrino beam produced at JPARC 295 km away. Near detectors will be installed and commissioned by the end of the year in order to take data in early 2010. In this poster, I will describe the status of the on axis near detector, INGRID, in addition to its contribution to the physics goals of the T2K experiment. (author)

[en] It is shown that empirical relations between the charged lepton spectra and the quark spectra together with a bimaximal or near bimaximal neutrino mixing matrix necessarily imply that there is a contribution to vertical bar U_e3 vertical bar given by θ_C/32∼m_e/2m_μ∼0.052, where θ_C is the Cabibbo angle. This prediction could be tested in the near future reactor experiments. The charged lepton mixing also generates a less robust prediction for the angle θ₂₃ and a small contribution to the phase δ

[en] The quark mixing matrix is parameterised such that its ''Cabibbo substructure'' is emphasised. One can choose one of the parameters to be an arbitrarily chosen angle of the unitarity triangle, for example, the angle β (also called Φ₁)

[en] A summary of constraints on the CKM angle γ from recent LHCb analyses are discussed. The results of a combination of several LHCb measurements of γ are presented, giving $\mathrm{\gamma <!--\; ??\; -->}=({70.9}_{{}_{-<!--\; ???\; -->8.5}}^{{}^{+7.1}}{)}^{\circ <!--\; ???\; -->},$ where the single uncertainty is a combination of statistical and systematic sources. This represents the most precise measurement of the angle γ. (paper)

[en] Cabibbo angle and quark-lepton masses are derived from a composite model by taking into account the interaction between the internal degrees of freedom

[en] All solutions of the standard Cabibbo model and the Spectrum Generating Group model are obtained which are allowed by the latest experimental data excluding the value for αsub(e) sup(Σ^-→ne upsilon). With the values of the parameters fixed by these experimental data, predictions of the various models for αsub(e) sup(Σ^-→ne upsilon) and other yet unmeasured decay parameters are obtained. It is shown that for most of the decay parameters there are only minor differences between the predictions from the various models, except for αsub(e) sup(Σ^-→ne upsilon) and αsub(upsilon) sup(Σ^-→ne) where the differences are significant.

[en] Quark-lepton unification suggests Cabibbo-sized effects in lepton mixings, which we call Cabibbo haze. We give simple examples and explore possible Wolfenstein-like parametrizations of the MNSP matrix which incorporate leptonic Cabibbo shifts. We find that the size of the CHOOZ angle is not always correlated with the observability of CP violation

[en] It is shown that empirical relations between the charged lepton spectra and the quark spectra together with a bimaximal or near bimaximal neutrino mixing matrix necessarily imply that there is a contribution to |U_e3| given by θ_C/ 3√2 ∼ √(m_e/2m_μ) ∼ 0.052, where θ_Cis the Cabibbo angle. This prediction could be tested in the near future reactor experiments. The charged lepton mixing also generates a less robust prediction for the angle θ₂₃ and a small contribution to the phase (delta)
