InvalidCmd : not supported format standalone_msP

Asked by Alexander

I run model

https://github.com/LHC-DMWG/model-repository/tree/master/models/Pseudoscalar_2HDM

p p > z xd xd~ [noborn=QCD] (xd is dark matter)

and I try decay z > mu+ mu- in madspin (madspin = ON)

# specify the decay for the final state particles
decay z > mu+ mu-
# running the actual code
launch

It generates me LHE events, but z does not decay.

and it end up with a message

INFO: generating the production square matrix element
INFO: generate p p > z xd xd~ [sqrvirt=QCD] ;
Command "generate_events " interrupted with error:

Hi,

We do not have any perfect way to handle decay for loop-induced. So you need to decide on something to give up.
In this case, the best is likely to let pythia8 to decay it.

This is something on my todo list (but this is not moving very fast on it).

Cheers,

Olivier
