The proton structure function is re-deduced from the data of deep inelastic electron-proton scattering after enhanced correction that is made due to the multiple scattering effect. The Glauber approach is used to account for the multiple scattering of electron with the quark constituents of the proton. The results are compared with the prediction of the parton model. Appreciable deviation is ob...
The QCD expectations for the behaviour of the deep inelastic scattering structure functions in the region of small values of the Bjorken parameter x are summarized. The Balitzkij, Lipatov, Fadin, Kuraev (BFKL) equation which sums the leading powers of α s ln(1/x) is described and confronted with the " conventional " formalism based on the leading order QCD evolution equations. The small x behav...
1 Executive Summary E12-06-104 seeks to perform measurements of the ratio R = σ L /σ T of longitudinal to transverse cross sections in pion electroproduction. The emphasis will be on measurements in the so-called semi-inclusive deep inelastic scattering region, where essentially no information exists on the value of R, with extensions into the exclusive region. Whereas inclusive scattering cann...
Recent measurements of the diffractive cross section in deep-inelastic scattering (DIS) at HERA are presented. The data are used to investigate the factorisation properties of diffractive DIS and to examine its quantum chromodynamic (QCD) structure. Models based on the colour dipole approach to DIS are also tested. 1. Diffractive Deep Inelastic Scattering At low x in DIS at HERA, approximately ...
On the basis of the target mass corrections to structure functions of deep-inelastic scattering of leptons, we evaluate effective nucleon mass that turns out to be twice M nucl. for deep-inelastic scattering on the nucleus target and equals M nucl. for the hydrogen target.
Deep inelastic lepton-hadron scattering has played a fundamental role in the investigation of hadron structure. For example, the discovery of Bjorken scaling confirmed the existence of point-like charged objects inside the nucleon (quarks). Besides such fundamental discoveries, deep inelastic scattering (DIS) revealed surprising and interesting details about the structure of nucleons and nuclei...
We discuss shadowing corrections to the structure function F2 in neutrino deep-inelastic scattering on heavy nuclear targets. In particular, we examine the role played by shadowing in the comparison of the structure functions F2 measured in neutrino and muon deep inelastic scattering. The importance of shadowing corrections in the determination of the strange quark distributions
The working group on two photon physics concentrated on three main subtopics: modelling the hadronic final state of deep inelastic scattering on a photon; unfolding the deep inelastic scattering data to obtain the photon structure function; and resonant production of exclusive final states, particularly of glueball candidates. In all three areas, new results were presented.
Recent results from jet production in deep inelastic ep scattering to investigate parton dynamics at low x are reviewed. The results on jet production in deep inelastic scattering and photoproduction used to test perturbative QCD are discussed and the values of αs(MZ) extracted from a QCD analysis of the data are presented.
