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

. 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
Zp:vq

)
vector coupling of quarks.
Zp:vX
(
default =
0.1
)
vector coupling of the Dark Matter
X
particles.
