Supersymmetric U (1) Y′ ⊗ U (1) B - L extension of the Standard Model
(2017-06-10)
We build a supersymmetric version with SU(3)C ⊗ SU(2)L ⊗ U(1)Y′⊗ U(1)B-L gauge symmetry, where Y′ is a new charge and B and L are the usual baryonic and leptonic numbers. The model has three right-handed neutrinos with ...

The KASCADE-Grande energy spectrum of cosmic rays and the role of hadronic interaction models
(ElsevierAmsterdam, 2014-05)
Previous results obtained by KASCADE-Grande using the QGSjetII-02 hadronic interaction model have shown that the energy spectrum of cosmic rays between '10 POT. 16' eV and '10 POT. 18' eV exhibits a significant hardening ...
Comments about some species abundance patterns: classic, neutral, and niche partitioning models
(Int Inst Ecology, 2008-11-01)
The literature on species abundance models is extensive and a great deal of new and important contributions have been published in the last three decades. Broadly speaking, one can recognize five families of species abundance ...
