abstract

• The observation of a charm-strange meson D sJ (2632) along with two decay modes of D η and D 0K , was investigated. A peak with 101 events over a combinatoric background of 54.9 events at a mass of 2635.4∓3.3 MeV/c 2 was observed in the D s η decay mode. In the D 0K decay mode, a corresponding peak of 21 events over a background of 6.9 at 2631.5∓2.0 MeV/c 2 was observed. The results show a clear peak of 43.4∓9.1 events with a Poisson fluctuation probability <6×10 -6 at a mass difference of 666.9∓3.3 MeV/c 2.
