Estimated CPU time required : 5400 hours (with PentiumIII 450MHz)


Estimated disk space usage required : 500 GB


Estimated HPSS space usage required : 0.1TB

Target date for completion : 15/04/02

Purpose and merit of the simulation including kinds of events being
simulated :

Future Transversity measurements with PHENIX and STAR require the
knowledge of spin dependent fragmentation functions. These functions
can be measured in e+e- annihilation at KEKB/Belle. The fragmentation
function analysis of Belle requires a detailed study of possible
detector acceptance effects. It is necessary to produce three times
the number of actual Belle physics data events as Monte Carlo including
a full simulation of the Belle detector response.

We propose to carry out 2.5% of the required MC production for the
Belle experiment 11. Experiment 11 corresponds to 10fb^-1 or
40*10^6 physics events. The production of 2.5% corresponds to 3*10^6
MC events requiring  about 5400 h of 450MHz Pentium III CPU time.
This initial test job will serve to evaluate the possibilities to
carry out Belle MC-production on CCJ. We hope to carry out the MC-
production for 2-3 Belle experiments/year.
