Multiquark description of the DsJ(2860) and DsJ(2700)

Within a theoretical framework that accounts for all open-charm mesons, including the D* 0 (2308), the D* sJ (2317), and the D sJ (2460), we analyze the structure and explore possible quantum number assignments for the D sJ (2860) and the D sJ (2700) mesons reported by BABAR and Belle Collaborations. The open-charm sector is properly described if considered as a combination of conventional quark-antiquark states and four-quark components. All negative parity and 2 + states can be understood in terms only of qq components, however the description of the 0 + and 1 + mesons is improved whenever the mixing between two- and four-quark configurations is included. We analyze all possible quantum number assignments for the D sJ (2860) in terms of both cs and cns n configurations. We discuss the role played by the electromagnetic and strong decay widths as basic tools to distinguish among them. The broad structure reported by BABAR near 2.7 GeV is also analyzed.
