Charmonium spectroscopy

Abstract

In this paper we review the status of charmonium spectroscopy. After a description of the experimental techniques used for the study of charmonium, we review the present knowledge of the cc spectrum below and above the open charm threshold. We discuss recent developments and future opportunities.

Decay of the scalar charmonium state $\chi_{c0}(IP)$ in the extended Linear Sigma Model

“…Notice that the decays of charmonium states into the open charmed mesons are forbidden in the eLSM as the same outcomes in Ref. [33]. The parameters were determined in Refs.…”

Development of electromagnetic calorimeter detectors and simulations for spectroscopic measurements of charmonium with PANDA

“…The review of charmonium physics outlined below is based on the review articles by Bianco et al [30], which covers theory of charmonium, Bettoni and Calabrese [29] which describes the current status of experiments, QWG report [34] which covers both theoretical and experimental aspects of charmonium physics, reviews given in several PhD theses (e.g. [80], [67]) on charmonium physics and on original papers which are referred to in the text.…”

Charmonium spectrum and new observed states

“…Correspondingly, the mass of 2 −+ 1 1 D 2 is predicted to be 3.890 GeV. Within the charmonium framework, X(3872) was ever interpreted as the 1 3 D 2 and 1 3 D 3 [51]. These arrangements could also be checked.…”
