[Rivet] ATLAS analyses: ATLAS_2012_I1203852 and ATLAS_2013_I1190187

[Katerina Moudra]

Hi Andy,

Thank you for the comments. The overlap removal comparison in the 2013 code is meant to test both muons and antimuons and so should be changed to abspid(). 

Thanks again

Katerina

Hi Kiran, Oldrich, Katerina,

Thanks for these analyses. I have done a bit of code and info file
tidying but without changes to the behaviour. Here is the updated form
in the Rivet repository:

https://rivet.hepforge.org/trac/browser/src/Analyses/ATLAS_2012_I1124167.cc

I saw one bit of code in the 2013 analysis which is a bit odd:

// e/mu overlap removal
if (l1.constituentLepton().pid() == PID::MUON)
isolated_lepton.push_back(l1); //keep mu

All the other overlap comparisons, including those immediately above
this in the code, are using Particle::abspid() [note: buggy in 2.1.1,
will be fixed in 2.1.2!] or abs(Particle::pdgId()) or similar. Is this
one *really* meant to just test for muons and not antimuons, or should I
change it to use abspid()?

Thanks again,
Andy

PS. Please remember the Rivet inRange, sqr, and cmpBy* functions: many
things that don't need to be rewritten, and which can help to make your
code more readable and maintainable. There are also now functions like
sortByPt(vector_of_jets_or_particles) and any(vec, function) & all(vec,
function) routines will appear in the next release. Check the
Rivet/Tools/Utils.hh, Rivet/Math/MathUtils.hh, Rivet/Math/Vector4.hh and
Rivet/ParticleBase.hh headers for lots of such useful things.
