Problem with four scalars interaction

Asked by Alessandro Davoli on 2018-11-28

Hi,

I implemented a model on top of SM with two scalars ~a0 and ~h0 (the reason of the ~ symbol is only to interface with micromegas as well), which interact via an interaction of the type ~a0 ~a0 ~h0 ~h0.

When I try to generate the process, I get the following message

Error when reading /Users/alessandrodavoli/Library/MG5_aMC_v2_6_4/bin/prova/SubProcesses/P1_xa0xa0_xh0xh0/G1/results.dat
Command "generate_events run_01" interrupted with error:
ValueError : need more than 5 values to unpack
Please report this bug on https://bugs.launchpad.net/mg5amcnlo
More information is found in '/Users/alessandrodavoli/Library/MG5_aMC_v2_6_4/bin/prova/run_01_tag_1_debug.log'.
Please attach this file to your report.

but I don't understand origin of the problem.

I also attach the run_01_tag_1_debug.log file

Thanks

Alessandro

In this directory:
/Users/alessandrodavoli/Library/MG5_aMC_v2_6_4/bin/prova/SubProcesses/P1_xa0xa0_xh0xh0/G1/
you should find some log file which should contains more information about what went wrong on that computation.

Cheers,

Hi,

Looks like that the particle with PDG #7 has it's color set to "2".
This does not make sense to me. Can you check if your model has correctly that particle (as a singlet, since it decays into to singlet)

Cheers,

Olivier

Actually there is no particle with PDG = 7.

Here is the .fr file I implemented on top of the SM.

In addition, the same UFO works fine on another machine, so I was wondering if it can depend on some dependences or something like that.

Thanks
Alessandro

Would you be able to put your UFO model somewhere online (or to send it to me by email with a link to this thread).
I would need it to investigate this.

Hi,

Ok, it seems that MGaMC, is adding automatically a fake particle in order to be able to perform the phase-space integration.
The problem is that such technique is not compatible with the default scale choice for mur and muf.
So the solution is quite simple:
change the dynamical scale (to either fix scale or to a simpler dynamical scale choice)
In my test, i have use
set dynamical_scale_choice 3
(this means HT/2)
and it works nicely.
