Dark Matter Processes
This page contains the production of Dark Matter via new s-channel
mediators. Currently only vector-like mediator i.e. Z'^0 for
Dirac DM is implemented. Note that the mediator in this case carries
the PDG id 55.
Z'^0
This group currently contains only one subprocess.
Scattering f fbar →Z'^0 → X Xbar.
Code 6001.
The couplings of the Z'^0 to quarks and leptons are be
assumed universal, i.e. generation-independent. Currently only vector
couplings are implemented. The choice of fixed axial and vector
couplings implies a resonance width that increases linearly with the
Z'^0 mass. Note that cross sections strongly depend on the
choice of mediator and Dark Matter masses.
Here are the couplings
