Transition form factors for $D / B$ to $a_{0} (980)$ from light-cone QCD sum rules

Di Gao, Jiangshan Lan, Duojie Jia +2

We apply the light-cone QCD sum rules with chiral currents to compute transition form factors of the semileptonic decay of the charmed and bottom scalar mesons $D / B$ to $a_{0}(980)…

Twist-2 distribution amplitudes of $a_{0} (980)$ and $a_{0} (1450)$

Wei Hong, Di Gao, Yanjun Sun

We investigate the twist-2 distribution amplitudes of the scalar mesons $a_{0} (980)$ and $a_{0} (1450)$ in the two-quark picture. The moments of these scalar mesons are obtained up…

Study on the Distribution Amplitude of the Scalar Meson $K_{0}^{*} (1430)$

Chen Wang, Yuanyuan Ma, Zhijun Wang +1

Based on sum rules, we explore the twist-2 distribution amplitude of the $K_{0}^{*} (1430)$ meson, treating it as the ground state of a quark-antiquark system. We posit that the spaceti…
