Five texture zeros in the lepton sector and neutrino oscillations at DUNE
Richard H. Benavides, D. V. Forero, Luis Muñoz +3
In this work, we have assumed special structures for the charged and neutral mass matrices in the lepton sector, inspired by structures for the up and down quark mass matrices that…
Systematic study of the local gauge symmetry
Richard H. Benavides, Yithsbey Giraldo, Luis Muñoz +2
We review in a systematic way how anomaly free models without exotic electric charges can be constructed, using as basis closed sets of fermi…
Singlet fermion dark matter and Dirac neutrinos from Peccei-Quinn symmetry
Cristian D. R. Carvajal, Robinson Longas, Oscar Rodríguez +1
The Peccei-Quinn (PQ) mechanism not only acts as an explanation for the absence of strong CP violation but also can play a main role in the solution to other open questions in part…
Five Texture Zeros for Dirac Neutrino Mass Matrices
Richard H. Benavides, Yithsbey Giraldo, Luis Muñoz +2
In this work we propose new five textures zeros for the mass matrices in the lepton sector in order to predict values for the neutrino masses. In our approach we go beyond the Stan…
Size and Shape Constraints of (486958) Arrokoth from Stellar Occultations
Marc W. Buie, Simon B. Porter, Peter Tamblyn +130
We present the results from four stellar occultations by (486958) Arrokoth, the flyby target of the New Horizons extended mission. Three of the four efforts led to positive detecti…
Charged current anomalies in a general boson scenario
John D. Gomez, Néstor Quintero, Eduardo Rojas
Very recent experimental information obtained from the Belle experiment, along with that accumulated by the BABAR and LHCb experiments, has shown the existence of anomalies in the…
