Abstract

© 2021 Elsevier B.V.In this study, the properties of the JPC=1++ hidden charm poles are analyzed under the variation of the bare 2P charmonium mass within the effective field theory proposed in Ref. [1]. The main focus of the current work is on the pole trajectory of the χc1(2P) charmonium dressed by the DD¯⁎ meson loops. It is shown that the trajectories of the pole change radically for values of the bare charmonium mass above a certain value and also depending on how close the pole is to the threshold.
