Pionic and radiative transitions from $$T_{c\bar{s}0}^+(2900)$$ to $$D_{s1}^+(2460)$$ as a probe of the structure of $$D_{s1}^+(2460)$$

Abstract

AbstractIn this work, we evaluated the widths of the pionic and radiative transitions from the $$T_{c\bar{s}0}^{+}(2900)$$ T c s ¯ 0 + ( 2900 ) to the $$D_{s1}^{+}(2460)$$ D s 1 + ( 2460 ) in the $$D_{s1}^{+}(2460)$$ D s 1 + ( 2460 ) molecular frame and the $$D_{s1}^{+}(2460)$$ D s 1 + ( 2460 ) charmed-strange meson frame. Our estimations demonstrate that the transition widths in the $$D_{s1}^{+}(2460)$$ D s 1 + ( 2460 ) molecular frame are much larger than those in the the $$D_{s1}^{+}(2460)$$ D s 1 + ( 2460 ) charmed-strange meson frame. Specifically, the ratio of the widths of $$\Gamma (T_{c\bar{s}0}^{+}(2900)\rightarrow D_{s1}^{+} \pi ^{0})$$ Γ ( T c s ¯ 0 + ( 2900 ) → D s 1 + π 0 ) and $$\Gamma (T_{c\bar{s}0}^{+}(2900)\rightarrow D^{+(0)}K^{0(+)})$$ Γ ( T c s ¯ 0 + ( 2900 ) → D + ( 0 ) K 0 ( + ) ) is estimated to be around 0.1 in the $$D_{s1}^{+}(2460)$$ D s 1 + ( 2460 ) charmed-strange meson frame, whereas the lower limit of this ratio is 0.67 in the $$D_{s1}^{+}(2460)$$ D s 1 + ( 2460 ) molecular frame. Thus, the aforementioned ratio could be employed as a tool for testing the nature of the $$D_{s1}^{+}(2460)$$ D s 1 + ( 2460 ) .
