Description
We report on the use of the GEANT4E, the track extrapolation feature written
by Pedro Arce, in the analysis of data from Belle experiment: (1) to project
charged tracks from the tracking devices outward to the particle identification
devices, thereby assisting in the identification of the particle type of each
charged track, and (2) to project charged tracks from the tracking devices
outward to the muon-detection device and then perform progressive
Kalman-like track fitting by combining (and correcting) the projected track
with the hits in the muon detector. To allow for the combination of GEANT4
detector simulation with event reconstruction in one program, we use the
novel technique of merging the GEANT4 and GEANT4E physics lists through
the instantiation and use of distinct particles for GEANT4E.
