Observation of new narrow $\mathrm{D_s}$ states
| Popis: | 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. |
