Production of neutral and doubly charged partners of D_{s0}^+(2317)

Abstract

Production of neutral and doubly charged partners, ${\hat{F}}_I^0$ and ${\hat{F}}_I^{++}$, of $D_{s0}^{+}(2317)$ as a charm-strange four-quark meson is studied in relation to observations of $D_{s0}^{+}(2317)$. It is discussed that observation of ${\hat{F}}_I^{++}$ in inclusive $e^{+}{e}^{-}\to c\bar{c}$ is difficult but it might be observed in $B_u^{+}\to D_s^{+}{\pi }^{+}{D}^{-}$. Observations of ${\hat{F}}_I^0$ and ${\hat{F}}_0^{+}$ might be possible in hadronic B decays.
