Please note that the file you are going to download (04F2E1EA-4470-E011-8F25-0018F3D09614.root) is 889090372 bytes big. On an average ADSL connection, it may take several hours to download it (about 2 hours at 1Mbps).

Moreover, if you use one of the provided Virtual Machines to perform your analyses, then you don't need to download datasets manually, because the VM will fetch all the necessary file chunks via the XRootD protocol.

Manual download of files via HTTP is only necessary if you would prefer not to use the XRootD protocol for one reason or another.

How were these data selected?

Since the actual ZeroBias triggers were moved to the MinimumBias dataset, the remaining events do not contain useful information and this sample should not be used.

How were these data validated?

During data taking all the runs recorded by CMS are certified as good for physics analysis if all subdetectors, trigger, lumi and physics objects (tracking, electron, muon, photon, jet and MET) show the expected performance. Certification is based first on the offline shifters evaluation and later on the feedback provided by detector and Physics Object Group experts. Based on the above information, which is stored in a specific database called Run Registry, the Data Quality Monitoring group verifies the consistency of the certification and prepares a json file of certified runs to be used for physics analysis. For each reprocessing of the raw data, the above mentioned steps are repeated. For more information see:

How can you use these data?

You can access these data through the CMS Virtual Machine. See the instructions for setting up the Virtual Machine and getting started in

Issues & Limitations

This dataset contains all runs from 2010 RunB. However, the ZeroBias dataset does not contain any validated runs. It is therefore NOT recommended to perform analysis on this dataset. The list of validated runs, which must be applied to all analyses, can be found in
