Setting Higgs BRs when using MadSpin
Hello,
In 2.6.7, we run a process like this:
import model loop_sm-no_b_mass
define p = g u c d s b u~ c~ d~ s~ b~
define j = g u c d s b u~ c~ d~ s~ b~
define w = w+ w-
define ttbar = t t~
generate p p > ttbar w Z [QCD]
output -f
If I explicitly write into the param card the decays of the Higgs according to the yellow report:
DECAY 25 6.382339e-03
5.767E-01 2 5 -5 # H->bb
6.319E-02 2 15 -15 # H->tautau
2.192E-04 2 13 -13 # H->mumu
2.462E-04 2 3 -3 # H->ss
2.911E-02 2 4 -4 # H->cc
8.569E-02 2 21 21 # H->gg
2.277E-03 2 22 22 # H->gammagamma
1.539E-03 2 22 23 # H->Zgamma
2.146E-01 2 24 -24 # H->WW
2.641E-02 2 23 23 # H->ZZ
then we get an error:
InvalidParamCard : yukawa (2, 22) is already define to 22 22 impossible to assign 22 23
If we don't set the decays, the job runs without a problem. My suspicion was that this is coming from the branching fraction of H->gamma gamma and H->Z gamma being set somehow, but I don't understand how this is an issue. Could you help me understand the error?
Thanks,
Zach

I would need the full param_card in order to be able to comment/test

Just to add, that i have tried to add such lines for that model and I did not face any issue.
Could you also put the debug file, such that I know which part of the codes complains.

Olivier

Hi Olivier,
this should be the debug file in question, param card will come in a separate message.

Hi,
I just wanted to nudge this thread in case there's been any progress.
Thanks again,

Hi,
Ah I did not realize from the first message that the issue was not on the event generation but within MadSpin (actually in the automatic computation of the width since it seems that it is requested since the Z has not branching ratio information.
The issue seems related to a missing space for the branching ratio information.
I will look for a patch but they are two easy work-around:
1) add a space in front of those lines
2) add the BR information for the Z
Cheers,
Olivier
