We investigate the possibility of explanation for the muon anomalous magnetic moment $g_\mu-2$ in a left-right model with an inverse seesaw mechanism. We emphasize that the observed deviation from the Standard Model predictions can be…
In this note, we show how one can attribute the anomaly currently present in the measurement of the anomalous magnetic moment of the muon ($a_\mu$) to the presence of an underlying Aligned 2-Higgs Doublet Model (A2HDM) with Right-Handed…
Very recently, a Fermilab report of muon $g-2$ showed a $4.2\sigma$ discrepancy between it and the standard model (SM) prediction. Motivated by this inspiring result and the increasing tension in supersymmetric interpretation of the…
The $\mu\nu$SSM is a supersymmetric standard model that solves the $\mu$ problem of the MSSM using the R-parity breaking couplings between the right-handed neutrino superfields and the Higgses in the superpotential, $\lambda_{i} \hat…
If the one term $(\hat \nu_e \hat \mu - \hat e \hat \nu_\mu) \hat \tau^c$ is added to the MSSM (Minimal Supersymmetric Standard Model) superpotential, the recently observed muon g--2 (anomalous magnetic moment) excess can be explained very…
Bilinear R-parity violating supersymmetric model is a viable model which can explain the smallness of neutrino masses and the mixing pattern in the lepton sector. In this model, there is a common set of parameters which determine the…
