Deep-inelastic structure functions: Reconstruction from Mellin moments
The precision measurement of structure functions and their scale evolution in deep inelastic scattering [1–3] is of basic importance for testing perturbative QCD. By now, experimental data allows for an accurate determination of the parton distribution functions, which serve as input for numerous other hard scattering processes. Therefore, in particular with respect to the upcoming LHC experime...
متن کاملThe Mellin moments of deep inelastic structure functions at two loops
We perform the analytic calculation of the Mellin moments of the structure functions F2 and FL in perturbative QCD up to second order corrections and in leading twist approximation. We calculate the 2-loop contributions to the anomalous dimensions of the singlet and non-singlet operator matrix elements and the 2-loop coefficient functions of F2 and FL. Our results are in agreement with earlier ...
متن کاملOff-shell Corrections and Moments of the Deep Inelastic Nuclear Structure Functions
We present an improved method of handling off-shell effects in deep inelastic nuclear scattering. With a firm understanding of the effects of the nuclear wavefunction, including these off-shell corrections as well as binding effects and nucleon-nucleon correlations, we can begin to examine the role of QCD in nuclei through an analysis of the moments of the nuclear inelastic structure function F...
متن کاملPhenomenology of Deep Inelastic Scattering Structure Functions
I review recent progress in analysing deep inelastic scattering structure functions in global analyses. The new ingredients are new data and attempts to incorporate heavy quarks consistently. A new way of including the resummation of large log 1/x terms is discussed. INTRODUCTION Since we last met in Rome last year there has been progress in our understanding of deep inelastic scattering (DIS) ...
متن کاملFroissart Boundary for Deep Inelastic Structure Functions
In this letter we derive the Froissart boundary in QCD for the deep inelastic structure function in low x kinematic region. We show that the comparison of the Froissart boundary with the new HERA experimental data gives rise to a challenge for QCD to explain the matching between the deep inelastic scattering and real photoproduction process. ∗ E-mail: [email protected] ∗∗ E-mail:[email protected]...
