    Symmetries and blind spots in the dark
    Abstract: Discrete symmetries play an important role in constructing Beyond Standard Model (BSM) scenarios that can explain phenomena such as neutrino mass, dark matter (DM), etc. I will begin with a brief discussion and a few examples of how discrete symmetries can provide explanations for phenomena that the SM cannot explain. In the latter part, I will discuss DM phenomenology in a three Higgs doublet model (3HDM) in terms of the blind spot narrative, where the DM-nucleon scattering cross-section vanishes due to mutual cancellations among the model parameters. This can eventually explain the non-observation of DM in direct detection experiments.
