A model independent analysis of the leptonic Dirac CP‐violating phase ({\delta}) is presented. The analysis uses the experimentally determined values of the mixing angles in the lepton mixing matrix in order to explore the allowed values for {\delta} and possible general forms for the charged lepton mixing matrix. This is done under two general assumptions: 1) that the mixing matrix in the...

We deal here with the off‐shell renormalization of the chiral effective Lagrangian for physics beyond the Standard Model, based on a non‐linear realization of the $SU(2)_L\times U(1)_Y$ gauge symmetry breaking in the presence of a light Higgs particle, up to four derivatives. We consider the full would‐be Goldstone bosons and Higgs sector of the Lagrangian. All one loop amplitudes are computed...

After the successful determination of the reactor neutrino mixing angle \mbox{$\theta_{13} \cong 0.16 \neq 0$}, a new feature suggested by the current neutrino oscillation data is a sizeable deviation of the atmospheric neutrino mixing angle $\theta_{23}$ from $\pi/4$. Using the fact that the neutrino mixing matrix $U = U^\dagger_{e}U_{\nu}$, where $U_{e}$ and $U_{\nu}$ result from the...
