Description
The design of a general jet tagging algorithm for the ATLAS detector reconstruction
software is presented.
For many physics analyses, reliable and efficient flavour identification, 'tagging',
of jets is vital in the process of reconstructing the physics content of the event.
To allow for a broad range of identification methods emphasis is put on the
flexibility of the framework. A guiding design principles of the jet tagging software
is a strong focus on modularity and defined interfaces using the advantages of the
new ATLAS Event Data Model and object oriented C++. The benefit for the developer is
modularity of the design in terms of expandability of the tagging software with
additional and modified algorithms. The user profits from common interfaces to all
algorithms and also from a simple jet tagging configuration. The usage of different
methods, re-doing the tagging procedure with a modified setup and combining the
results from various methods during the analysis.
The ATLAS b-tagging algorithms have been migrated into this new jet tagging
environment and the concrete implementation is used to demonstrate the benefits of
the proposed design.
