Deep Inelastic Scattering from Light Nuclei
For the past 20 years the nuclear EMC effect — the nuclear medium modification of the nucleon structure functions — has posed a serious challenge to models of the nucleus which involve quark degrees of freedom. Although the basic features of the EMC effect can be understood within a conventional nuclear physics framework, a quantitative description over the entire range of Bjorken-x appears bey...
متن کاملDeep Inelastic Scattering
Recent deep inelastic results from the H1 collaboration are presented. The topics covered include inclusive diffractive physics, the determination of αS using the event shapes, the study of the hadronic final state at low x with single particles and with jets, the structure function measurements in particular F p 2 at low Q and the high Q physics both in neutral and charged current.
متن کاملDeep Inelastic Scattering, Diffraction
These lectures include an introduction to the partonic description of the proton, the photon and the ‘colour singlet’, as seen in inclusive and semi-inclusive DIS, in e+e− collisions, and in diffractive processes, respectively. Their formal treatment using structure, fragmentation, and fracture functions is outlined giving an insight into the perturbative QCD framework for these functions. Exam...
متن کاملDo Sum Rules in Deep Inelastic Scattering Follow from Qcd?
We consider restrictions imposed on the electromagnetic and weak current operators by Poincare invariance and show that some assumptions used in deriving the sum rules in deep inelastic scattering (DIS) have no physical ground. In particular there is no ground to neglect the contribution of nonperturbative effects to these operators, even in the Bjorken limit. Therefore the conclusion that the ...
متن کاملPolarized Deep Inelastic Diffractive Scattering near the Light Cone
Inclusive unpolarized and polarized deeply inelastic diffractive scattering at high energies and momentum transfer is one of the important processes in lepton–nucleon scattering. As found by experiment, cf. [1], there are interesting relations between the cross sections of these processes and those of inclusive deeply inelastic scattering: i) the scaling violations of both processes are quite s...
