Systematic errors of bound-state parameters obtained with SVZ sum rules
We study systematic errors of the ground-state parameters obtained by Shifman– Vainshtein–Zakharov (SVZ) sum rules, making use of the harmonic-oscillator potential model as an example. In this case, one knows the exact solution for the polarization operator, which allows one to obtain both the OPE to any order and the parameters (masses and decay constants) of the bound states. We determine the...
متن کاملA History of Feynman’s Sum over Histories in Quantum Mechanics
Exact calculations of Feynman’s path integrals (defined on a time lattice) are mainly based on recurrence integral formulas in which the convolution of two functions having a common feature retains the same feature. Therefore, exactly soluble path integrals in quantum mechanics may be classified by their recurrence integral formula used in the calculation. According to this classification, ther...
متن کاملParton-Hadron duality in QCD sum rules: quantum mechanical examples
Motivated by recent work on three-point QCD sum rules in heavy quark physics, we use the simple quantum mechanical models to study the basic issue of duality in three-point sum rules. We show that while in all of these models the duality in two-point sum rules works fine, the duality in three-point sum rules may be 100%violated, leading to completely unreliable predictions for the matrix elemen...
متن کاملAsymptotic Limits and Sum Rules for Propagators in Quantum Chromodynamics
In gauge field theories with asymptotic freedom, the short distance properties of Green’s functions can be obtained on the basis of weak coupling perturbation expansions. Within this framework, the large momentum behavior of the structure functions for gluon, quark and ghost propagators is derived. The limits are found for general, covariant, linear gauges, and in all directions of the complex ...
متن کاملSum rules and bath parametrization for quantum cluster theories
We analyze cellular dynamical mean-field theory CDMFT and the dynamical cluster approximation DCA . We derive exact sum-rules for the hybridization functions and give examples for dynamical mean-field theory, CDMFT, and DCA. For impurity solvers based on a Hamiltonian, these sum rules can be used to monitor convergence of the bath-parametrization. We further discuss how the symmetry of the clus...
