AB  - The BABAR experiment has discovered a new narrow state, D^*_sJ(2317)^+, near 2.32 GeV in the inclusive D_s^+ pi^0 invariant mass distribution from e^+e^- annihilation data at energies near 10.6 GeV. The same experiment has also shown evidence for structure in the 2.46 GeV region in the D^*_s(2112)^+ pi^0 mass spectrum. These discoveries have triggered several experiments in a search for new states coupled to the D_s^+ meson which confirmed the existence of D^*_sJ(2317)^+ together with D_sJ(2458)^+ -> D^*_s(2112)^+ pi^0 both in inclusive e^+ e^- annihilation and in B decays. These two new states are difficult to explain in terms of potential models.
