Simple question regarding FastJet
Hello,
I am working on a p p > h j, h > j j l v process. I am using aMC@NLO to generate LO events. I use PYTHIA8 in the aMC@NLO framework for shower. Then I use the generated .hep file in ./bin/ma5 -R, using the following settings for my attempt at a jet algorithm:
set main.fastsim.
set main.fastsim.
set main.fastsim.radius = 0.4
set main.fastsim.ptmin = 20.0
set main.fastsim.
set main.outputfile = higgs.lhe
import ~/higgs_
submit
The .lhe output file is essentially the same (now instead of quark and antiquark, it is 2 protons) as data produced after PYTHIA8. My question is, is the above correct? Why is fastjet not really doing anything? Shouldn't all of the gluons and quarks be hadronized? What is the typical output from running fastjet.
I'm also confused because the spectator quarks should hadronize and form jets (but these are not at all considered in this because Madgraph only includes a quark and anti-quark)? Surely this is a fundamental flaw if we're trying to simulate the behaviour in the detector?
Thank you,
James
