What is Meson vs. Diquark Structures in Tetraquark about?

This document explores the structure of the b̄b̄ud tetraquark with quantum numbers I(J P ) = 0(1+) using lattice QCD computations, focusing on the relative importance of meson-meson and diquark-antidiquark creation operators. The study finds that the diquark-antidiquark structure dominates at small separations, while the meson-meson state becomes more relevant at larger separations, estimating a ratio of approximately 60% meson-meson to 40% diquark-antidiquark. The findings contribute to the understanding o
