Abstract

The understanding of the hadron-hadron interaction is an important topic nowadays. To encourage new experiments seeking for evidence of theoretical predictions, it is essential to make a detailed theoretical investigation of the possible existence of bound states and resonances, despite some uncertainty in contemporary interaction models. It is the purpose of this project to analyze the interaction of two hadrons with charm and its application to study the possible existence of hadronic molecules, either in the free space or in nuclear matter. When tackling this problem, one has to manage with an important difficulty, namely the complete lack of experimental data. Thus, the generalization of models describing the two-hadron interaction in the light flavor sector could offer insight about the unknown interaction of hadrons with heavy flavors. This research project pretends to advance on the knowledge of the interaction between hadrons with charm by means of the generalization of models successfully developed for light hadron systems. It will address the properties, and in particular, it will pursue the study of bound states and resonances, of two hadron systems with charm in the free space and in hot and dense matter. For this purpose, we will make use of microscopic quark models that will be generalized for nuclear matter by means of the Nambu-Jona-Lasinio scheme and QCD sum rules. The final goal is to obtain predictions that may be testable in experiments at the LHC and in the future European experiments at FAIR, and also at the Jefferson Lab, J-PARC or SuperB. (AU)
