The inverse seesaw mechanism has been claimed to be consistent with existing bounds while accommodating the muon anomalous magnetic moment (g-2). We revisit this idea and review the importance of nonunitarity bounds over the inverse seesaw mechanism, either in the canonical version or when it is embedded in extended gauge theories. We show that, when nonunitarity constraints are brought into place, the inverse seesaw mechanism fails to accommodate the g-2 anomaly.
The electroweak (EW) sector of the Minimal Supersymmetric Standard Model (MSSM), with the lightest neutralino as Dark Matter (DM) candidate, can account for a variety of experimental data. This includes the DM content of the universe, DM direct detec
The new measurement of the muons anomalous magnetic moment released by the Muon g-2 experiment at Fermilab sets strong constraints on the properties of many new particles. Using an effective field theory approach to the interactions of higher-spin fi
We explore the implications of LHC and cold dark matter searches for supersymmetric particle mass spectra in two different grand unified models with left-right symmetry, $SO(10)$ and $ SU(4)_c times SU(2)_L times SU(2)_R$ (4-2-2). We identify charact
The present work introduces two possible extensions of the Standard Model Higgs sector. In the first case, the Zee-Babu type model for the generation of neutrino mass is augmented with a scalar triplet and additional singly charged scalar singlets. T
We propose a predictive $Q_4$ flavored 2HDM model, where the scalar sector is enlarged by the inclusion of several gauge singlet scalars and the fermion sector by the inclusion of right handed Majorana neutrinos. In our model, the $Q_4$ family symmet
