New particle definitions give errors that I don't understand

Asked by GSA on 2018-06-05

Greetings,

I am trying to write a new particle into madgraph via Feynrules UFO, and upong importing the model and running the command
generate g g > X X~, I run into this problem:
KeyError : 'PRIVATE`GetIntOrder[P$IndexDelta[Index[Colour, Ext[1]], Index[Colour, Int[1]]]]'

I was wondering if anyone could help explain what this means to me? I do not know what the error is saying, and thus, am unable to take any measures to fix it.

Thank you very much for your time guys, and have a great day!

Sincerely,
GSA

Hi,

This is a typically FeynRules issue, when some variable are wrongly contracted (not fully sure).
My suggestion is to ask help to FeynRules author. Can not really help you on that.

Cheers,

Olivier

Thank you for your feedback Mr.Olivier! I will try to ask around (Feynrules authors) and figure this out. Have a great day!

Can you help with this problem?
