Run atlas_2003_11956 over the files here: https://www.dropbox.com/s/uaa91743egy6op4/tag_1_pythia8_events.hepmc.gz?dl=0

Run checkmate over 2 event sample -- bonus points if the analysis is DV+mu.

For the samples mentioned here:

#5 (comment)

let's make a plot of the final signal acceptance for the MET region as a function of the neutralino lifetime. That is to say, in that screenshot, we look at line 25 and read off the value 0.01 from the Acc column. We want that number for the 1 TeV, 200 GeV mass point (for stop and chi0 masses respectively) as a function of the lifetime to see how it changes.

Hi @taylorsussmane -- @kdipetri pointed out a little bug in the code where we're asking for a pdgid 13 and not -13. Can we add an abs around the PDGID?

Using the main document: https://atlas.web.cern.ch/Atlas/GROUPS/PHYSICS/PAPERS/SUSY-2018-33/hepdata_info.pdf

Calculate the "magnitude of the transverse component of the vector sum of the momenta of all muons and stable weakly-interacting particles in the final state."

Calculate it for each event, and make a histogram of the values and post here.

Then we're going to throw away events that have truth met < 100 GeV.

The dummy cross section we've been using is 1 fb (femtobarn). We'll instead need this to be the cross section of the processes as defined here:

(There are also JSON files available)

@taylorsussmane will implement calculations of acceptance definitions (page 1 of https://atlas.web.cern.ch/Atlas/GROUPS/PHYSICS/PAPERS/SUSY-2018-33/hepdata_info.pdf)

Aiming for end of this week.

Once reasonable results are achieved with #2 and #4, we should be running over a grid of events to achieve r values (Checkmate Term) as a function of the lifetime and mass of the neutralinos.
