2 brief CheckMATE2 analysis question regarding 13TeV analysis & the Total p+ p+ cross section

[AdamKimForster]

Deear CheckMATE team.

Firstly, thanks for the super useful software :)

I have 2 brief question:

1. I have been running a 13TeV analysis (see attached .txt file). However, when I look at the Pythia log files they say "We collide p+ with p+ at a CM energy of 8.000e+03 GeV” (see line 154 of attached .log file). Am I doing something wrong?

2. I am looking for an output of the total p+ p+ cross section. I have found some references to cross sections but it is not clear to me that they refer to p+ p+ and not to specific sub processes. Do you know how I can find the total p+ p+ cross section?

Any help would be greatly appreciated.

Hi Adam,

sorry for our late reply. It seems to me that there might be a bug in CM. Could you try atlas13TeV and/or cms13TeV, please?

Regarding the total cross section. It's given in the pythia log. You can "grep" for "| sum" and then should find it. It's given in units of millibarn. I have just copied the relevant part below.

Cheers,

Jong

Hi

Thanks very much for your help!

I have just tried cms and atlas runs and it seems the same problem is occurring (see attached files).

I installed this version of checkmate a couple of years ago. I will try installing a more up to date version
