Step 2: Available Data Sets in DST format

For the tutorial we provide several data samples providing DST data. The first is a Z' sample where the Z' has a mass of 700 GeV and is forced to decay into 2 muons. This sample contains 1000 events. The other sample is a sample of Higgs with a mass of 300 GeV which decays into 2 Z0 where one is forced to decay into a pair of electrons and the other decays into a pair of muons. This sample contains 500 events. Both samples don't contain any pile up.

In the last part of this tutorial we will see two examples demonstrating how to access this data sets. To access this data use the following lines in your .orcarc files (or equivalent):

For the Z'(700) --> mu mu (ORCA 8.0.1 and OSCAR 2.4.6):

InputFileCatalogURL = @{xmlcatalog_file:/storage/data2/uaf/tutorial/zpmumu/PoolFileCatalog.xml}@
InputCollections = /System/myDST/zprime_mumu

For the H(300) --> Z0 Z0 --> ee mumu (ORCA 8.0.1 and OSCAR 2.4.6):

InputFileCatalogURL = @{xmlcatalog_file:/storage/data2/uaf/tutorial/h300eemm/PoolFileCatalog.xml}@
InputCollections = /System/myDST/h300eemm

A new version of ORCA was released since the tutorial you might want to start with the following data sample which was created with the latest and greatest version of ORCA (as of April 27th 2004). (the difference to 8.0.1 is mainly that a bug affecting the ECAl clusters has been fixed.)

For the Z'(700) --> mu mu (ORCA 8.1.1 and OSCAR 2.4.6):

InputFileCatalogURL = @{xmlcatalog_file:/storage/data2/uaf/tutorial/zpmumu_8.1.1/PoolFileCatalog.xml}@
InputCollections = /System/myDST/zprime_mumu

3. Event generation on the farm with CMKIN (Pythia), Analysis of the generator level output.
4. Simulate the events with OSCAR.
5. Digitize with ORCA and produce DST's
6. Run a muon ROOT Tree maker looking at the DST and make some simple plots
