Semi-inclusive Deep Inelastic Electron Scattering off the Deuteron and the Neutron to Proton Structure Function Ratio
نویسنده
چکیده
The production of slow nucleons in semi-inclusive deep inelastic electron scattering off the deuteron is investigated in the region x > 0.3. It is shown that within the spectator mechanism the semi-inclusive cross section exhibits a scaling property even at moderate values of Q2 (∼ few (GeV/c)2) accessible at present facilities, like CEBAF . Such a scaling property can be used as a model-independent test of the dominance of the spectator mechanism and provides an interesting tool to investigate the neutron structure function. The possibility of extracting model-independent information on the neutron to proton structure function ratio from semi-inclusive experiments is illustrated. The application of the spectator scaling to semi-inclusive processes off complex nuclei is outlined. PACS numbers: 13.40.-f; 13.60.Rj; 14.20.Dh; 25.30.Rw

Investigation of the Neutron Structure Function via Semi-inclusive Deep Inelastic Electron Scattering off the Deuteron
The production of slow nucleons in semi-inclusive deep inelastic electron scattering off the deuteron is investigated in the region x ∼ > 0.3 for kinematical conditions accessible at HERA. Within the spectator mechanism the semi-inclusive cross section exhibits a scaling property, which can be used as a model-independent test of the dominance of the spectator mechanism itself, providing in this...
متن کاملSemi-inclusive Electron Scattering off the Deuteron and the Neutron Structure Functions
The detection of slow nucleons in semi-inclusive electron scattering processes off the deuteron, 2H(e, eN)X, is a very promising tool for the extraction of model-independent information on the neutron structure function Fn 2 (x,Q 2). The key point is the occurrence of a peculiar scaling property of the semi-inclusive cross section, which holds in the deep-inelastic regime as well as in the nucl...
متن کاملSemi - inclusive Pion Production and the d / u Ratio
We explore the feasibility of directly extracting the large-x valence d/u ratio through a measurement of pions in the current fragmentation region of semi-inclusive deep-inelastic scattering from protons. The d/u ratio contains important information about the flavor structure of the proton. In particular, its asymptotic behavior at large x can tell us which mechanism is responsible for the brea...
متن کاملHow well do we know the neutron structure function?
We present a detailed analysis of the uncertainty in the neutron F(2n) structure function extracted from inclusive deuteron and proton deep-inelastic scattering data. The analysis includes experimental uncertainties as well as uncertainties associated with the deuteron wave function, nuclear smearing, and nucleon off-shell corrections. Correctly accounting for the Q(2) dependence of the data an...
متن کاملNeutron single spin asymmetries from semi-inclusive deep inelastic scattering off transversely polarized 3He
A study of semi-inclusive deep inelastic scattering off transversely polarized 3He is presented. The formal expressions of the Collins and Sivers contributions to the azimuthal single spin asymmetry for the production of leading pions are derived, in impulse approximation, and estimated in the kinematics of forth-coming experiments at JLab. The AV18 interaction has been used for a realistic des...
