Test of the α-expansion method for extracting the hadronic spectrum in QCD: The harmonic oscillator
Abstract
The recently proposed α-expansion method for calculation of the hadronic spectrum in QCD is tested by the simple example of the harmonic oscillator. It appears that three terms of the expansion of the generalized S-matrix at large momenta are sufficient to calculate the whole spectrum to very good accuracy.
