In this work we introduce scalar leptoquarks into the 3-3-1 model with right-handed neutrinos with the aim of solving the (g−2)μ puzzle. We show that besides the model supports leptoquarks in the octet, sextet, triplet and singlet representations,

Ten years ago the 125 GeV Higgs resonance was discovered at the LHC [1,2], if this boson is a fundamental particle or a particle composed of new strongly interacting particles is still an open question. If this is a composite boson there are still no

In its original version, the minimal 3-3-1 model possess a Landau-pole around 2-6 TeV scale. Current LHC bound on Z′ implies that the SU(3)L×U(1)X symmetry must break spontaneously around 4 TeV which means that the model may lose its perturbative

In this work, we introduce the minimal set of leptoquarks into the 3-3-1 model with right-handed neutrinos, capable of generating radiative masses for active neutrinos. As a main consequence, the standard neutrinos acquire small Majorana masses at th

Abstract We discuss fermion mass generation in unified models where QCD and technicolor (or any two strongly interacting theories) have their Schwinger–Dyson equations coupled. In this case the technicolor (TC) and QCD self-energies are modified in

The magnetic moment of the muon can receive significant two-loop contributions from the scalar spectrum in Two Higgs Doublet Models (THDM), particularly for a light pseudoscalar. It is established that the symmetry breaking from $SU(3)_L \times U(1)_

Abstract The technicolor (TC) Schwinger–Dyson equations (SDE) should include radiative corrections induced by extended technicolor (ETC) interactions when TC is embedded into a larger theory including also QCD. These radiative corrections couple th

Theories with large mass anomalous dimensions (γm) have been extensively studied because of their deep consequences for models where the scalar bosons are composite. Large γm values may appear when a non-Abelian gauge theory has a large number of f

Bioprocesses are often characterized by nonlinear and uncertain dynamics. This poses particular challenges in the context of model predictive control (MPC). Several approaches have been proposed to solve this problem, such as robust or stochastic MPC
