From Moments to Functions in Quantum Chromodynamics
نویسندگان
چکیده
Single-scale quantities, like the QCD anomalous dimensions and Wilson coefficients, obey difference equations. Therefore their analytic form can be determined from a finite number of moments. We demonstrate this in an explicit calculation by establishing and solving large scale recursions by means of computer algebra for the anomalous dimensions and Wilson coefficients in unpolarized deeply inelastic scattering from their Mellin moments to 3-loop order.

Baryons as Solitons in Three Dimensional Quantum Chromodynamics
We show that baryons of three dimensional Quantum Chromodynamics can be understood as solitons of its effective lagrangian. In the parity preserving phase we study, these baryons are fermions for odd N c and bosons for even N c , never anyons. We quantize the collective variables of the solitons and there by calculate the flavor quantum numbers, magnetic moments and mass splittings of the baryo...
متن کاملMeasurement of Inclusive Proton Double-Spin Asymmetries and Polarized Structure Functions
PAGE The scattering of polarized electrons from a polarized proton target provides a means for studying the internal spin structure of the proton. The CLAS (CEBAF Large Acceptance Spectrometer) EG1b experiment in Hall-B at Jefferson Laboratory measured double-spin inclusive and exclusive electron-nucleon scattering asymmetries using longitudinally polarized frozen NH3 and ND3 targets and a long...
متن کاملSlac-pub-95-6937 Precision Tests of Quantum Chromodynamics and the Standard Model *
We discuss three topics relevant to testing the Standard Model to high precision: commensurate scale relations, which relate observables to each other in pertuba-tion theory without renormalization scale or scheme ambiguity, the relationship of compositeness to anomalous moments, and new methods for measuring the anomalous magnetic-and quadrupole moments of the W and 2.
متن کاملQUANTUM - CHROMODYNAMIC PREDICTIONS FOR DIRECT PHOTONS IN e + e - COLLISIONS
We analyze the direct photon production in e+ecollisions in quantum chromodynamics using the cut vertex formalism and renormalization group method. The two-loop anomalous dimensions of time-like cut vertices are calculated from the two-loop parton decay probability functions. The moments of the transverse structure function $ are calculated up to the next-to-leading order. The nonleading correc...
متن کاملSum Rules and Moments of the Nucleon Spin Structure Functions
The nucleon has been used as a laboratory to investigate its own spin structure and Quantum Chromodynamics. New experimental data on nucleon spin structure at low to intermediate momentum transfers combined with existing high momentum transfer data offer a comprehensive picture of the transition region from the confinement regime of the theory to its asymptotic freedom regime. Insight for some ...
