چکیده

We discuss the spin-dependent structure function g2(x,Q ) in the framework of the operator product expansion. It is noted that the anomalous dimensions and coefficient functions for the twist-3 gluon-field-dependent operators depend on the choice of the operator basis. The role played by the operators proportional to the equation of motion is clarified. HUPD-9503 January, 1995

Renormalization of Twist-4 Operators in QCD Bjorken and Ellis-Jaffe Sum Rules

The QCD effects of twist-4 operators on the first moment of nucleon spin-dependent structure function g1(x,Q ) are studied in the framework of operator product expansion and renormalization group method. We investigate the operator mixing through renormalization of the twist-4 operators including those proportional to the equation of motion by evaluating off-shell Green’s functions in the usual...

We analyze the twist-4 contributions to Bjorken and Ellis-Jaffe sum rules for spin-dependent structure function g1(x,Q ). We investigate the anomalous dimensions of the twist-4 operators which determine the logarithmic correction to the 1/Q behavior of the twist-4 contribution by evaluating off-shell Green’s functions in both flavor non-singlet and singlet case. It is shown that the EOM operato...

Evolution equation for the structure function g 2 ( x , Q 2 )

We perform an extensive study of the scale dependence of flavor-singlet contributions to the structure function g 2 (x, Q 2) in polarized deep-inelastic scattering. We find that the mixing between quark-antiquark-gluon and three-gluon twist-3 operators only involves the three-gluon operator with the lowest anomalous dimension and is weak in other cases. This means, effectively, that only those ...

Evaluation of the Higher Twist Contribution to the Moments of Proton Structure Functions

We performed the measurement of the inclusive electron scattering off the proton [1, 2] in the resonance region (W < 2.5 GeV) at momentum transfer Q below 4.5 (GeV/c) with the CLAS detector. The large acceptance of CLAS provided an access to a large, continuous two-dimensional kinematic domain in Q and x, allowing therefore an integration of the data at fixed Q over x-interval. The covered x-in...

Renormalization of twist-three operators and integrable lattice models. Abstract We address the problem of solution of the QCD three-particle evolution equations which govern the Q 2-dependence of the chiral-even quark-gluon-quark and three-gluon correlators contributing to a number of asymmetries at leading order and the transversely polarized structure function g 2 (x Bj). The quark-gluon-qua...
