Abstract
Physical world is built on particles, yet our knowledge of how they created is limited. In Belle experiment, exclusive 2-, 3-, & 4-Body charm meson events are studied which leads to the understanding of particle creation.
Models like PYTHIA (string model) or HERWIG (cluster model) fail to describe our result, while factorization (pQCD) with Quasi-particle seem to be success. Preliminary results of cross section, production angle, Xp, event topology, V/PS ratio and resonances will be presented and discussed. Still there are more works and challenges.
