Some Phenomenologies of a Simple Scotogenic Inverse Seesaw Model

TL;DR

This paper explores a combined inverse seesaw and scotogenic model, analyzing electroweak parameters and dark matter relic density, highlighting challenges in detecting loop effects but potential for future experimental verification of neutrino counts.

Contribution

It introduces a phenomenological study of a novel combined model, calculating electroweak parameters and assessing experimental detectability of loop effects and neutrino counts.

Findings

Loop effects on $R_l$ and $A_l$ are hard to detect with current data.

$N_{ u}^l$ can be large enough for future experiments to observe.

Dark matter relic density constraints are incorporated.

Abstract

In this paper, we discuss and calculate the electroweak parameters $R_l$, $A_l$, and $N_{\nu}^l$ in a model that combine inverse seesaw with the scotogenic model. Dark matter relic density is also considered. Due to the stringent constraint from the ATLAS experimental data, it is difficult to detect the loop effect on $R_l$, $A_l$ in this model considering both the theoretical and future experimental uncertainties. However, $N_{\nu}^l$ can sometimes become large enough for the future experiments to verify.
