Ann Arbor - LCD workshop - March 1999

Java Analysis Studio

• Experiment independent Physics Analysis Tool
  • Histogram Creation, Manipulation and Display
  • Easy to download and install on Windows or Unix
  • Works with hep.lcd classes for LCD specific analysis

What is hep.lcd ?

• hep.lcd a Java framework for
  • Analysis of LCD data from
    • Stdhep, Gismo, Root FASTMC
  • Running Reconstruction and Parameterized (Fast) MC
  • Rapid development of reconstruction and analysis algorithms
  • Event Display, Analysis Tools
  • Can be used inside JAS or standalone

What is hep.lcd

• Why Java?
  • More appropriate language than C++ for data analysis
    • Easy to learn
    • Simpler to use
    • Huge industry support
