Abstract The $$\eta ^{(\prime )}$$ η ( ′ ) -mesons in the quark-flavor basis are mixtures of two mesonic states $$|\eta _{q}\rangle =|{\bar{u}} u+{\bar{d}} d\rangle /\sqrt{2}$$ | η q ⟩ = | u ¯ u + d ¯ d ⟩ / 2 and $$|\eta _{s}\rangle =|{\bar

Abstract Based on the scenario that the $$K_0^*(1430)$$ K 0 ∗ ( 1430 ) is viewed as the ground state of $$s\bar{q}$$ s q ¯ or $$q\bar{s}$$ q s ¯ , we study the $$K_0^*(1430)$$ K 0 ∗ ( 1430 ) leading-twist distribution amplitude (DA) $$\phi _{2;

In the paper, we investigate the moments $\langle\xi_{2;a_1}^{\|;n}\rangle$ of the axial-vector $a_1(1260)$-meson distribution amplitude by using the QCD sum rules approach under the background field theory. By considering the vacuum condensates up t
