Pseudoscalar Mesons

We calculate the second moment [Formula: see text] of the flavor-singlet structure function [Formula: see text] for the pion and the kaon in the framework of the QCD sum rule, and investigate how the results depend on their flavor structure (quark contents). Our calculations give similar values of [Formula: see text] for these two mesons as a result of the cancellation among several non-small factors.

In this paper, we tentatively assign the [Formula: see text] to be the [Formula: see text] type vector tetraquark state and study its two-body strong decays with the QCD sum rules based on solid quark–hadron duality, the predictions for the partial decay widths [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text] can be compared to the experimental data in the future to diagnose the nature of the [Formula: see text].
