Introduction into QCD Sum Rule Approach
[hep-ph/0410394] Theta++ from QCD sum rule - In QCD sum rule approach, a correlation function of an interpolating field is calculated by the use of the operator product expansion (OPE), and is compared with the spectral representation via dispersion relation. The sum rules relate hadron properties to the vacuum expectation values of QCD operators (condensates), such as …
