Chiral Symmetry Breaking in QCD: A Variational Approach

C. Arvanitis, F. Geniet, J. -L. Kneur +1

We develop a "variational mass" expansion approach, recently introduced in the Gross--Neveu model, to evaluate some of the order parameters of chiral symmetry breakdown in QCD. The…

Convergence of the Optimized Delta Expansion for the Connected Vacuum Amplitude -- Anharmonic Oscillator

C. Arvanitis, H. F. Jones, C. S. Parker

The convergence of the linear expansion for the connected generating functional of the quantum anharmonic oscillator is proved. Using an order-dependent scaling for the variati…
