      Hands-on session on recasting and relic density calculation for dark photons: Hands-on session

      Optional hands-on session on running Micromegas to calculate the relic density in freeze-out and freeze-in scenarios (https://lapth.cnrs.fr/micromegas/) and on recasting dark photon limits (https://gitlab.com/philten/darkcast)

      • 09:00
        Darkcast hands-on 1h 30m
        Speaker: Philip Ilten (University of Birmingham (GB))

        Prerequisites to get darkcast to work on lxplus:

        needs logging in with a graphical session (conda will look for DISPLAY)
        when you ask to put the miniconda directory in your PATH say no
        export PATH=/afs/cern.ch/user/d/doglioni/Work/miniconda2/bin:$PATH
        conda create --name=darkcastenv python=2.7
        source activate darkcastenv
        conda install -c conda-forge matplotlib
        every time you log in:
        export PATH=/afs/cern.ch/user/d/doglioni/Work/miniconda2/bin:$PATH
        source activate darkcastenv

        How to install and run darkcast example:

        tar -xzvf darkcast-master.tar.gz
        mv darkcast-master darkcast
        cd darkcast/examples
        python invisible.py
