Open Charm Decays of Exotics

本课题组的所有研究项目都属于强子能谱领域。它的目标是回答强互动的最后几个问题。在这个研究小组中，对魅力和光夸克制度中的奇异状态的搜索和调查/表征是令人感兴趣的。奇异态的内部结构不同于强子基态(介子和重子)。到今天为止，只有少数几个异国的候选者可以被识别出来。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奇异终态的信息，独立地研究几个终态是很重要的。只有沿着这条道路，才有可能区分不同的模型。在这个研究项目中，只会研究和刻画包含一对“迷人的”介子的终态，一个具有魅力夸克，第二个具有反魅力夸克(开放魅力终态)。这些衡量标准补充了研究组内另外两个研究项目的研究。他们用碳素或反重子-重子终态来研究终态。

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.
