Possible interpretations of D-sJ(+)(2632) if it really exists

AbstractWe analyze various possible interpretations of the narrow state D-sJ(+)(2632) observed by SELEX Collaboration recently, which ties above threshold and has abnormal decay pattern. These interpretations include: (1) several versions of tetraquarks; (2) conventional c (s) over bar meson such as the first radial excitation of D-s(2112) with abnormally large SU(3) symmetry breaking; (3) conventional c (s) over bar meson with abnormally large eta(1) coupling; (4) heavy hybrid meson. We discuss the physical implications of each interpretation. For example, if the existence of D-sJ(+)(2632) is confirmed as the first radial excitation of D-s(2112) by other experiments, it will be helpful to took for (1) its SU(3) flavor partners D-J(0,+)(2530); (2) its B-meson analogues B-J(0,+)(5840) B-sJ(+)(5940); (3) S-wave two pion decay modes. We also discuss possible reasons of negative results in search of D-sJ(+)(2632) by other experiments.
