Aims

• To provide an interface between physics
  simulations (HERWIG, PYTHIA) and ATLAS detector
  simulations (ATHENA, ATLFAST).
• To use this to investigate methods of measuring
  WW ? WW events at the LHC with the ATLAS
  detector.

• Other Future Developments
• The perceived superiority of the Kt jet algorithm
  over the cone jet algorithm could be tested.
• ATLFAST could be interfaced with another monte
  carlo simmulator called HERWIG and the results
  could then compared with the PYTHIA-ATLFAST
  package.

We shall not cease from exploration and the end
of all our exploring will be to arrive where we
started and know the place for the first time.
