Pionic and radiative transitions from T_{c(s)over-bar0}⁺(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 (s) over bar0(+)(2900) to the D-s1(+) (2460) in the D-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 (s) over bar0(+) (2900) -> D-s1(+)pi(0)) and Gamma (T-c (s) over bar0(+)(2900) -> D+(0) K0(+)) 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).
