MadSpin problem for 1->N process
Dear MG experts,
I am having trouble using MadSpin in 1->N processes. I want to look at the decay of a single particle into some two body state, and then letting these two particles decay. I am mainly using a modified version of the DMsimp model in the MG model repository with a scalar that couples to fermions with a scalar and a pseudoscalar coupling (but I also have trouble using just the usual SM, see below). For the fermions, I believe the only difference with respect to the DMsimp scalar model in the model repository is that the pseudoscalar coupling is defined without the complex i.
[ Similar SM problem:
I tried to run MadSpin with a similar ordinary SM process to see if the problem was with the UFO model I am using. It seems not, because the following commands give the same problem as for my UFO model:
./bin/mg5_aMC
generate h > t t~
output [OUTDIR]
launch
madspin=ON
set MH=500
where the madspin_card is set to contain the default commands:
set max_weight_ps_point 400
decay t > w+ b, w+ > all all
decay t~ > w- b~, w- > all all
decay w+ > all all
decay w- > all all
decay z > all all
launch
This results in the same compilation error for the map_external2res array as the one printed out below. ]
Is there a bug when using MadSpin for 1 -> N processes? Because it seems that I can get it to work when running e.g. e+e- collisions.
mg5_aMC is run with the following commands:
generate y0 > t t~
output [OUTDIR]
launch
madspin=ON
The madspin card contains here the following commands:
set max_weight_ps_point 400
decay t > w+ b, w+ > e+ ve
decay t~ > w- b~, w- > e- ve~
launch
Below is my debug file for the y0 > t t~ run (where I have replaced my user directory with "[USERDIR]"):
