OPE–RχT matching at order αs: hard gluonic corrections to three–point Green functions
In this work we push the matching between the QCD operator product expansion (OPE) and resonance chiral theory (RχT) to order αs. To this end we compute two– and three–point QCD Green functions (GFs) in both theories and compare the results. GFs which are order parameters of chiral symmetry breaking make this matching more transparent and thus we concentrate on those. On the OPE side one needs ...
متن کاملSymmetric low-rank corrections to quadratic models
In this paper, we study the quadratic model updating problems by using symmetric low-rank correcting, which incorporates the measured model data into the analytical quadratic model to produce an adjusted model that matches the experimental model data, and minimizes the distance between the analytical and updated models. We give a necessary and sufficient condition on the existence of solutions ...
متن کاملNumerical Approach to Two-loop Three Point Functions with Masses
The calculation of loop integrals is essential to obtain the precise theoretical prediction for high-energy reactions. Loop integrals for oneloop diagrams can be expressed by logarithms and dilogarithms. For a class of higher order diagrams, compact analytic expressions are obtained. For instance, some two-loop two point functions with single mass(m) are given by functions of x = s/m. As two-lo...
متن کاملQuadratic growth and critical point stability of semi-algebraic functions
We show that quadratic growth of a semi-algebraic function is equivalent to strong metric subregularity of the subdifferential — a kind of stability of generalized critical points. In contrast, this equivalence can easily fail outside of the semi-algebraic setting.
متن کاملThe cosmic shear three-point functions
We investigate the three-point functions of the weak lensing cosmic shear, using both analytic methods and numerical results from N-body simulations. The analytic model, an isolated dark matter halo with a powerlaw profile chosen to fit the effective index at the scale probed, can be used to understand the basic properties of the eight three-point functions observed in simulations. We use this ...
