Pionic and radiative transitions from T${}_{c\overline{s}0}^{+}$(2900) to D${}_{s1}^{+}$(2460) as a probe of the structure of D${}_{s1}^{+}$(2460)

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