Abstract

The traditional methods of estimating the Dark Matter (DM) mass scale crucially depend on the assumptions about the interaction mechanism between the DM and the Standard Model (SM) sectors, making it challenging to achieve precise mass measurements. However, in case of a successful scattering event of a high-energy matter beam on a DM particle, the DM mass can be directly measured without probing the New Physics (NP) interaction. The present chapter discusses a model-independent kinematical analysis to formulate the DM mass as a function of experimentally observable quantities. The approach can be significant to precisely pin-down the exact mass value of the interacting DM particle and offers insights into the DM-SM interaction strength.
