Dark Matter Physics at Different Mass Scales

Abstract:  We focus on a small subset out of the various issues plaguing the Standard Model. Employing a phenomenological framework, we tend to focus on dark matter physics. First we did an in-depth analysis of the potential observable consequences of the Higgs and Neutrino portal dark sector models at the Fermilab DarkQuest experiment, focusing on the GeV scale mass range. Then we reoriented ourselves towards the ultra light dark matter scenarios, where we analyzed the effects of the SM thermal bath towards the late time relic abundance for the scalar dark matter field, and putting together it's implications on the current and upcoming parameter space.
