Proton-Proton Collisions Data
The ATLAS Collaboration released over 6 billion proton-proton collisions with accompanying simulations. All these events were released in PHYSLITE format, a light format used internally for analysis.
Search for Data
Inside the main entry point of proton-proton collision open data you will find eleven different links that point to different datasets. These are explained below.
We have two datasets with detector data:
- Run 2 2015 proton-proton collision data: Detector data for the 2015 run, with an integrated luminosity of ~3.2 fb
- Run 2 2016 proton-proton collision data: Detector data for the 2016 run, with an integrated luminosity of ~33 fb
We have seven groups for Standard Model Monte Carlo samples. Four for nominal samples:
- MC simulation electroweak boson nominal samples.
- MC simulation Higgs nominal samples.
- MC simulation QCD jet nominal samples.
- MC simulation top nominal samples.
Three for alternative samples for the calculation of systematic variations (since the systematics for electroweak boson are included in the nominal datasets):
- MC simulation Higgs systematic variation samples.
- MC simulation QCD jet systematic variation samples.
- MC simulation top systematic variation samples.
And two groups for Beyond the Standard Model signal samples:
Combining samples
Often several Monte Carlo simulation samples must be combined in order to recreate the full background expected from the Standard Model. Some documentation explaining how this should be done is here.
