Assuming one of these experiments would succeed, the next question would be to study the properties of DM.\n\nOne question we could ask is if DM particles are their own anti-particles, a so-called Majorana fermion. This code determines the statistical significance with which a successful electron scattering experiment could reject the Majorana hypothesis (using the likelihood ratio test) in favour of the hypothesis of Dirac DM. We assume that the DM interacts with the photon via higher-order electromagnetic moments.\n\n\u003e :warning: **Warning**: In order for this code to produce results, the */data/* folder needs to contain the tabulated atomic response functions, which can be computed with the [DarkARC tool](https://github.com/temken/DarkARC).
