We present a comprehensive review of keV-scale sterile neutrino Dark Matter, collecting
views and insights from all disciplines involved—cosmology, astrophysics, nuclear, and …

In this work we build a gauge model based on the SU (3) c⊗ SU (3) L⊗ U (1) N symmetry
with heavy neutrinos and show that we can have two weakly interacting cold dark matter …

Motivated by the upcoming Higgs analyses, we investigate the importance of the
complementarity of the Higgs boson chase on the low-mass weakly interacting massive …

We have witnessed some flavor anomalies appearing in the past years, and explanations
based on extended gauge sectors are among the most popular solutions. These beyond the …

We propose two 3-3-1 models (with either neutral fermions or right-handed neutrinos) based
on S 3 flavor symmetry responsible for fermion masses and mixings. The models can be …

In this work we discuss a new SU (3) C⊗ SU (3) L⊗ U (1) X⊗ U (1) N (3-3-1-1) gauge model
that overhauls the theoretical and phenomenological aspects of the known 3-3-1 models …

We show that the SU (3) C⊗ SU (3) L⊗ U (1) X (3-3-1) model of strong and electroweak
interactions can naturally accommodate an extra U (1) N symmetry behaving as a gauge …

Within the context of vector mediators, is a new signal observed in flavor changing
interactions, particularly in the neutral mesons systems K 0− K¯ 0, D 0− D¯ 0 and B 0− B 0¯ …

A bstract The flipped 3-3-1 model discriminates lepton families instead of the quark ones in
normal sense, where the left-handed leptons are in two triplets plus one sextet while the left …

A bstract We propose an extension of the 3-3-1 model with an additional symmetry
group\({Z} _2\times {Z} _4\times\mathrm {U}{(1)} _ {L_g}\) and an extended scalar sector. To …
