Study on the Distribution Amplitude of the Scalar Meson $K_0^{\ast }(1430)$

Chen Wang, Yuanyuan Ma, Zhijun Wang +1

Based on sum rules, we explore the twist-2 distribution amplitude of the $K_0^{\ast }(1430)$ meson, treating it as the ground state of a quark-antiquark system. We posit that the spaceti…
