what does [QCD] mean ?

Asked by Ashutosh Kotwal

  What is the meaning of putting [ QCD ] after a process

i.e. what is the difference between

 generate p p > h t t~

and

 generate p p > h t t~ [ QCD ]

thanks,
Ashutosh

understood

now my real problem is that I am trying this process

p p > h j j [QCD]

and it is failing at the end in some "soft and collinear tests"

I put an eta Max of 4 on the jets, to prevent too-forward jets, but did not fix…

is this an NLO related test?

Hi Ashutosh,

I reply to you by email directly.
Just for the completeness, I put the answer here too:

This generate the diagrams needed for the NLO computation.

Cheers,

Olivier
