概要
- 論文の詳細を見る
The D^+_sπ^0 and D^<*+>_sγ decays of D^+_<sO>(2317) are studied by assigning it to various charmed strange scalar mesons. As a result, it is found that its assignment to an iso-triplet four-quark meson is favored by the severest experimental constraint on the ratio of the rates for these decays, while assigning it to an I=0 state (a four-quark or a conventional {cs^^-}) is inconsistent with this constraint.
