issue using Madspin with SMEFTsim model
Dear MadGraph experts,
I am planning to use MadGraph+Madspin to generate the following simple process:
g g > h.
Where i later decay the higgs to w+ w- with madspin.
This all when using the model: SMEFTsim_
I am interested in the behaviour of the h->ww->l- l+ vl~ vl channels when changing the EFT parameters.
in this case i just used the Standard model limit of the model.
generate g g > h
#
output PROC_full_ggf
the madgraph generation goes as expected, only when madspin is taking the higgs for decay i get the error
stty: standard input: Inappropriate ioctl for device
14:01:53Command "generate_events -f run_01 --nb_core=1" interrupted with error:
14:01:53 ZeroResult : No Phase Space. Please check particle masses.

14:01:53 Please report this bug on https:/

i have checked the param_card for the masses but they are all there.
I dont really know what i am missing here, to my knowledge i seem to have given everything madspin needs to decay the events.
also i set the spinmode to none since this is necessary for higgs decay
All of the cards/settings ect that i am using are here including the generation log of the job.

Q1 is there a fix to this issue?
Q2 Is it preferable to use madspin for the decay for when using EFT models, or is t better to decay with MG5?
this question since i am working with the interference terms of the BSM with the SM.
So in the final i would like to generate g g > h NP^2 ==0, g g > h NP^2 ==1, g g > h NP^2 ==2. for several EFT parameters turned on.
this prevents me from using the decay chain syntax like g g > h, (h > w+ w-, w+ >l+ vl, w- > l- vl~). Since i am interested in the full decay i am now using for example the syntax g g > h > l+ l- vl vl~ for ggf and p p > h > l+ l- vl vl~ for vbf to generate
Am i doing it right this way? Since the reason i moved to madspin is the very long computation time of p p > h > l+ l- vl vl~ for vbf because of the many diagrams. I think it would be faster if i could generate only the production and then decay with madspin.
Thank you for your time,
Kind regards,
Bryan
