ZeroBias primary dataset in AOD format from RunB of 2010
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

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.
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:
