✦ Synopsis

The renormalization of chiral perturbation theory is carried out to next-to-next-to-leading order in the meson sector. We calculate the divergent part of the generating functional of Green functions of quark currents to O( p 6 ) for chiral SU(n), involving one-and two-loop diagrams. The renormalization group equations for the renormalized low-energy constants of O( p 6 ) are derived. We compare our results with previous two-loop calculations in chiral perturbation theory.

A comparison of sixth-order Mdler-Plesset perturbation energies (MP6) with the corresponding full configuration interaction (FCI) energies shows that in the case of equilibrium geometries MP6 values differ by just 1.7 mhartree. MP6 correlation energies turn out to be important for systems with oscil

We compare the properties of those published intermolecular perturbation theories whose behavior to infinite order is understood. From both fundamental and practical viewpoints we conclude that none is completely satisfactory. Since our current, detailed understanding of these theories is derived fr

The general expression for the sixth-order Msller-Plesset (MP6) energy, E(MP6), has been dissected in the principal part d and the renormalization part 9. Since 2 contains unlinked diagram contributions, which are canceled by corresponding terms of the principal part d, E(MP6) has been derived solel
