    Abstract: 研究期間:10108~10207;Electron-positron collider provides a much better platform for QCD studies than hadron colliders, and most hadrons are created from Vacuum via strong interactions. Therefore, Belle experiment should be the best choice to study interplay between Vacuum and particles. Experimental HEP group at NCU has many years experience in two-photon physics and Charm fragmentation studies. In this proposal, we try to focus on space-time structure down the size as splitting of gluon into quarks or quarks pairing as hadron. From data collected by Belle experiment, we shall compare similarities and differences among different reaction processes in particle creations. Through comparisons, one may understand how energy creates quarks from Vacuum via photon(s) or gluons, and how quarks are paired into hadron. Main theme e of this year study concentrates on comparison of γγ → ΡΡπ +π − and γ π π e + e− → * → D*−D+ + − two reactions. Preliminary analysis has shown their similarities and differences which shall help us to understand how quarks are created from Vacuum. These two topics shall be prepared as separated papers and published. Then their results will be put together and compared in order to understand rules followed in particle creation processes. In addition to these analyses γγ →ηη , γγ → KoK mπ ± s and D*−Doπ + three papers are expected to be published this year and another two-photon physics γγ →ηη / or γγ → PPπ o will enter its analysis stage as well. With great efforts from Dr Hideyuki Nakazawa, NCU group has taken charges of trigger monitoring and grand data processing in Belle experiment. Both of them are important to Belle data and belong to service natures. They are important contributions from a relative small group like NCU. Recent years, hospitals in Taiwan are planning or have scheduled for their particle therapy facilities. New facility needs “custom-designed” dose measurement system. HEP group at NCU combines efforts from other groups is developing detector system for dose measurement at future particle therapy facilities. A very first prototype has been built and tested at CGMH. Its performance shows normal characteristics. Works this year will be improvements in detector design and performance, electronics and DAQ, push overall performances to their limits. Prototypes are expected to be tested with electron beam at CGMH (Taiwan) or with proton beam at NCC-east (Japan).
