Asymptotic Padé-Approximant Methods and QCD Current Correlation Functions
Asymptotic Padé-approximant methods are utilized to estimate the leading-order unknown (i.e., not-yetcalculated) contributions to the perturbative expansions of two-current QCD correlation functions obtained from scalar-channel fermion and gluon currents, as well as from vector-channel fermion currents. Such contributions to the imaginary part of each correlator are polynomials of logarithms wh...
متن کاملPadé approximant related to the Wallis formula
Based on the Padé approximation method, in this paper we determine the coefficients [Formula: see text] and [Formula: see text] such that [Formula: see text] where [Formula: see text] is any given integer. Based on the obtained result, we establish a more accurate formula for approximating π, which refines some known results.
متن کاملDirect application of Padé approximant for solving nonlinear differential equations
UNLABELLED This work presents a direct procedure to apply Padé method to find approximate solutions for nonlinear differential equations. Moreover, we present some cases study showing the strength of the method to generate highly accurate rational approximate solutions compared to other semi-analytical methods. The type of tested nonlinear equations are: a highly nonlinear boundary value proble...
متن کاملPadé approximant related to asymptotics for the gamma function
Based on the Padé approximation method, we determine the coefficients [Formula: see text] and [Formula: see text] ([Formula: see text]) such that [Formula: see text] where [Formula: see text] is any given integer. Based on the obtained result, we establish new bounds for the gamma function.
متن کاملAsymptotic Padé Approximant Predictions: up to Five Loops in QCD and SQCD
We use Asymptotic Padé Approximants (APAP’s) to predict the fourand five-loop β functions in QCD and N = 1 supersymmetric QCD (SQCD), as well as the quark mass anomalous dimensions in Abelian and non-Abelian gauge theories. We show how the accuracy of our previous β-function predictions at the four-loop level may be further improved by using estimators weighted over negative numbers of flavours...
