We consider the issue of an accurate description of the evolution of the non-singlet structure function moments M n (Q) near heavy quark threshold. To this aim we propose a simple modification of the standard massless MS scheme approach to the next-to-leading QCD analysis of DIS data. We apply it to the processing of the modern CCFR data for xF 3 structure function and extract the value of α s ...

We show that, under a reasonable " smoothness " hypothesis, it is possible to extract informations on the amplitude and phase of two-body non-leptonic weak decay matrix elements from the study of Euclidean correlation functions in lattice QCD.

Spin dependent structure function g 1 at low x and low Q 2 B. Bade lek a,b Abstract Theoretical description of the spin dependent structure function g 1 (x, Q 2) in the region of low values of x and Q 2 is presented. It contains the Vector Meson Dominance contribution and the QCD improved parton model suitably extended to the low Q 2 domain. Theoretical predictions are compared with the recent ...

The leading nonperturbative QCD corrections to the one gluon exchange quark-quark, quark-antiquark and q ¯ q pair-excitation potentials are derived by using a covariant form of nonlocal two-quark and two-gluon vacuum expectation values. Our numerical calculation indicates that the correction of quark and gluon condensates to the quark-antiquark potential improves the heavy quarkonium spectra to...
