Polygonal Derivation of the Neutrino Mass Matrix
نویسنده
چکیده
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 study for some time. If Mν has less than the full 6 parameters, then there exists at least one relationship among masses and mixing angles, which may be tested against the increasingly more precise experimental data from neutrino oscillations. However, even if such a comparison is successful, the question still remains as to why it has such a form. A possible answer is that it comes from an underlying symmetry. In this paper, it is shown how M ν =

Oases in the Desert: Three New Proposals
Two new nontrivial U(1) gauge symmetries are proposed, one based on the particle content of the standard model and the other on that of its supersymmetric generalization. Each is an unexpected first example of its kind. A third new proposal is the successful derivation of a realistic Majorana neutrino mass matrix, based on the underlying symmetry A4 and its radiative corrections.
متن کاملOn Jordan left derivations and generalized Jordan left derivations of matrix rings
Abstract. Let R be a 2-torsion free ring with identity. In this paper, first we prove that any Jordan left derivation (hence, any left derivation) on the full matrix ringMn(R) (n 2) is identically zero, and any generalized left derivation on this ring is a right centralizer. Next, we show that if R is also a prime ring and n 1, then any Jordan left derivation on the ring Tn(R) of all n×n uppe...
متن کاملModel of Geometric Neutrino Mixing
Current neutrino oscillation data from solar, atmospheric, and reactor experiments are consistent with the neutrino mixing matrix elements taking values sin θ12 = 1/3, sin θ23 = 1/2, and sin 2 θ13 = 0. We present a class of renormalizable gauge models which realize such a geometric mixing pattern naturally. These models, which are based on the non–Abelian discrete symmetry A4, place significant...
متن کاملNeutrino Mass Matrix with Approximate Flavor Symmetry
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...
