Talk:QCD sum rules

Incomplete equation
In the introduction it says "we have inserted hadronic particle states on the right hand side." but there is no rhs to the equation. I also would say that the rhs should not be particle states but products of coefficient functions and low-energy (non-perturbative) expectation values like the gluon and quark condensates. 92.117.130.181 (talk) 10:26, 19 February 2022 (UTC)
