Open Charm Decays of Exotics

课题组的研究项目均属于强子光谱学领域。它的目标是回答强相互作用的最后几个问题。在这个研究小组中，对粲夸克和光夸克体系中奇异态的搜索和调查/表征是我们感兴趣的。外来态的内部结构不同于强子基态（介子和重子）。直到今天，只有少数外来国家的候选者能够被确定。为了得到一个确凿的答案，有必要测量具有相同内部结构的粒子的全谱。因此，为了获得尽可能多的关于外来最终态的信息，独立地研究几个最终态是很重要的。只有遵循这条道路，才有可能区分各种模型。在这个研究项目中，只有包含一对“迷人”介子的最终态将被研究和表征，其中一个具有迷人夸克，另一个具有反迷人夸克（开放迷人最终态）。这些测量补充了研究小组内其他两个研究项目的研究。他们用调和态或反重子-重子的最终态来研究最终态。

All research projects of this Research Group belong to the field of hadron spectroscopy. Its goal is to answer the last questions of the strong interaction. Within this Research Group the search and investigation/characterization of exotic states in the Charm- and the Light-Quark regime are of interest. The internal structure of exotic states is different from the hadronic ground states (mesons and baryons). Until today only a few candidates of exotic states could be identified. In order to get an conclusive answer it is necessary to measure the complete spectrum of particles with the same internal structure. Therefore, it is important to investigate several final states independently, in order to get as much information as possible about exotic final states. Only by following this path a discrimination between various models becomes possible.Within this research project only final states will be investigated and characterized which contain a pair of "charmed" mesons, one with a charm-quark and the second with an anticharm-quark (open charm final state). These measurements complement the studies of the two other research projects within the Research Group. They investigate final states with charmonium or antibaryon-baryon final states.
