A Study of DD^*K System — •Anuvind Asokan¹, Feng-Kun Guo^2,3,4, Christoph Hanhart¹, and Xu Zhang² — ¹Institute for Advanced Simulation 4, Forschungszentrum Jülich, D-52425 Jülich, Germany — ²CAS Key Laboratory of Theoretical Physics, Institute of Theoretical Physics, Chinese Academy of Sciences, Beijing 100190, China — ³School of Physical Sciences, University of Chinese Academy of Sciences, Beijing 100049, China — ⁴Peng Huanwu Collaborative Center for Research and Education, Beihang University, Beijing 100191, China

We present our investigation of the DD^*K system. This three-body system is of particular interest due to the presence of a bound state in each of the two-body subsystems — D_s0^*(2317) in DK, D_s1(2460) in D^*K and T_cc(3875) in DD^*, respectively. We employ a relativistic formalism using time ordered perturbation theory. We report the status of our calculations with special emphasis on poles location and width of the emerging three-body state.

Keywords: Exotic Hadrons; Hadronic Molecules; Few Body Systems
