Verne is a python code for calculating the Earth-stopping effect for super-heavy Dark Matter (DM).
The code allows you to calculate the speed distribution (and DM signal rate) at two detector locations: MPI (the Max-Planck-Institute in Munich) and SUF (the Stanford Underground Facility). This can be done for a range of DM masses and cross sections (though the results will be most reliable for very heavy DM particles). Further details about the physics behind the code can be found in arXiv:1712.04901.
The code will soon be updated with more detailed documentation and more examples. The core of the code (the
verne module) is in the src folder, head there for some details of how to use the code. More information about the inner workings will appear soon.
