Three jet events arising from decays of the Z bo-son, collected by the DELPHI detector, were used to measure differences in quark and gluon fragmentation. Gluon jets were anti-tagged by identifying b quark jets. Unbiased quark jets came from events with two jets plus one photon. Quark and gluon jet properties in different energy ranges were compared for the(More)
We present the strategy that has been adopted for the development of the software system for the LHCb experiment. This strategy follows an architecture-centric approach as a way of creating a resilient software framework that can withstand changes in requirements and technology. The software architecture, called GAUDI, covers event data processing(More)
A coherent O-O framework has been developed for describing the LHCb experimental apparatus to be used by the simulation, reconstruction and analysis applications. This framework is used for the realization of the detector data service, which is one of the main components of the GAUDI architecture in use in LHCb. Examples of detector description data are:(More)
The GAUDI software architecture, designed in the context of the LHCb experiment, maintains separate and distinct descriptions of the transient and persistent representations of the data objects. One of the motivations for this approach has been the requirement for a multi-technology persistency solution such that the best-adapted technology can be used for(More)
