  • Particles and PropertiesProperties of Particles are needed for analysisStandard source of data: Particle Data Group (PDG)But no database !Each software has its own databaseTwo areas: ParticlesGeneral Information (Mass, Width, etc.)Decay ModesFamily structure

  • Data Model: Particle-Families

  • .................

    XML-file: Family entry

  • Data Model: Particle

  • name:ASCII-Name of the Particletexname:Name of the Particle in LaTeX2e form some remarks for the physicists

  • JAS Java Analysis Studiohttp://jas.freehep.orgAnalysis software for high energy physicsAccess to XML-database via Java Interface

    ParticleProperties.setParticlePropertyProvider(new XMLParticlePropertyProvider(file));ParticleType pp = ParticleProperties.get( Particle_ID_Number); pp.getMass(); pp.getWidth(); etc.

  • ConclusionsXMLvery openplatform independentAbility to publish on the WebEasy accessible in many languages: Java, C++, Could be: one PDG data source for manyBut: difficult to get data out of PDG-book

  • Particle Data Group DatabaseA PDG Oracle database existsBut: A Database for printing the bookNo average values (like Mass, Width, etc.) without special Fortran calculation programs Postscript files generated by the databasePossibility to analyze the Postscript

  • Conclusions Part 2Status: Until today no reply from PDG, if we can get the actual databaseToDo:DocumentationPDG database import, if possiblePS import otherwise(Option: Frontend Editor for Particle administration)WEB-Page with all information
