Three Texture Zeros in the Hermitian Dirac sector within Type-I Seesaw Mechanism
Richard H. Benavides, John D. Gómez, William A. Ponce
We present numerical benchmark solutions for Hermitian Dirac neutrino mass matrices with three texture zeros within the type-I seesaw mechanism. The analysis is to normal ordering…
Higgs-like Resonances and Massive Neutrinos in a 3-3-1 Model

Richard H. Benavides, Yithsbey Giraldo, Eduardo Rojas
We explore the recently proposed gauge symmetry \( SU(3)_C \otimes SU(3)_L \otimes SU(3)_R \otimes U(1)_X \), which naturally embeds both the Left-Right symmetric model and the 3-3…
