Presently under construction in Lund, Sweden, the European Spallation Source (ESS) will
be the world's brightest neutron source. As such, it has the potential for a particle physics …

This paper includes two main parts. In the first part, we present generalized gauge models
based on the SU (3) C⊗ SU (4) L⊗ U (1) X (3-4-1) gauge group with arbitrary electric …

The so-called 3-3-1 models have been widely studied in the literature. However, in almost
all cases, as with other models, just simplified versions have been considered. On the other …

We prove that the Cotăescu general method of solving SU (3) c⊗ SU (n) L⊗ U (1) Y gauge
models exactly predicts the observed electric charge quantization, as the theory remains …

We propose here an enhanced version of the Standard Model based on the same local
gauge group SU (3) c⨂ SU (2) L⨂ U (1) Y that undergoes a spontaneous symmetry breaking …

Generating appropriate tiny neutrino masses via inverse seesaw mechanism within the
framework of a particular SU (3) c⊗ SU (4) L⊗ U (1) X gauge model is the main outcome of …

We study the neutrino mass generation in the SU (4) L⊗ U (1) X electroweak extension of
the Standard Model by considering nonrenormalizable dimension 5 effective operators. It is …

Within the framework of a renormalizable SU (5) L× U (1) Y electro-weak gauge model with
no exotic electric charges, we obtain all the neutral weak charge operators and their …

A new flipped SU (3) C⊗ SU (4) L⊗ U (1) X model without exotic electric charges is
proposed. All the quark families are arranged in the same representation while lepton …
