We show how introducing discrete Abelian flavor symmetries can produce texture zeros in the fermion mass matrices, while preserving the correct relationships with the low-energy data on quark and lepton masses. We outline a procedure for defining texture zeros as suppressed entries in Yukawa matrices. These texture zeros can account for the coexistence of the observed large mixing in atmospheri...

I report on the application of tmQCD techniques to the computation of hadronic matrix elements of four-fermion operators. Emphasis is put on the computation of B K in quenched QCD performed by the ALPHA Collaboration. The extension of tmQCD strategies to the study of neutral B-meson mixing is briefly discussed. Finally, some remarks are made concerning proposals to apply tmQCD to the computatio...

We assume there to be precisely three left-handed neutrino states whose Majorana masses are generated by an unspecified mechanism. Were CP conserved, the symmetric neutrino mass matrixM would be real and all six of its distinct entries could be experimentally determined. But CP is not conserved so that M is likely to be complex. As a result, not all nine of its convention-independent real param...

We suggest that the weak-basis independent condition det (Mν) = 0 for the effective neutrino mass matrix can be used in order to remove the ambiguities in the reconstruction of the neutrino mass matrix from input data available from present and future feasible experiments. In this framework, we study the full reconstruction of Mν with special emphasis on the correlation between the Majorana CP-...

Representations of the symmetry group Dn of the n−sided regular polygon have generic multiplication rules if n is prime. Using Dn with n = 5 or greater, a particular well-known form of the Majorana neutrino mass matrix is derived. **To appear in Fizika B (Zagreb) memorial issue dedicated to Dubravko Tadic. The form of the 3 × 3 Majorana neutrino mass matrix Mν has been the topic of theoretical ...

We present a systematic procedure to establish a connection between complex neutrino mass matrix textures and experimental observables, including the Dirac CP phase. In addition, we illustrate how future experimental measurements affect the selection of textures in the (θ13, δCP)-plane. For the mixing angles, we use generic assumptions motivated by quark-lepton complementarity. We allow for any...

Phenomenological implications of neutrino oscillations implied by recent experimental data on pattern of neutrino mass matrix are diss-cussed. It is shown that it is possible to have a neutrino mass matrix which shows approximate flavor symmetry; the neutrino mass differences arise from flavor violation in off-diagonal Yukawa couplings. Two modest extensions of the standard model, which can emb...

A novel element with arbitrary domain shape by using decoupled scaled boundary finite element (DSBFEM) is proposed for eigenvalue analysis of 2D vibrating rods with different boundary conditions. Within the proposed element scheme, the mode shapes of vibrating rods with variable boundary conditions are modelled and results are plotted. All possible conditions for the rods ends are incorporated ...

We have discussed predictions of Ue3 and JCP in the framework of the neutrino mass matrix with two zeros. The lower bound of Ue3 is 0.05, which depends on tan θ12 and tan θ23. We have investigated the stability of these predictions taking account of small corrections to zeros, which may come from radiative corrections or off-diagonal elements of the charged lepton mass matrix. We have found tha...
