Quasielastic versus Inelastic and Deep Inelastic Lepton Scattering in Nuclei
We have made a thorough investigation of the nuclear structure function W2A in the region of 0.8 < x < 1.5 and Q2 < 20 GeV2, separating the quasielastic and inelastic plus deep inelastic contributions. The agreement with present experimental data is good giving support to the results for both channels. Predictions are made in yet unexplored regions of x and Q2 to assert the weight of the quasie...
متن کاملDEEP INELASTIC LEPTON SCATTERING IN NUCLEI AT x > 1 AND THE NUCLEON SPECTRAL FUNCTION
The nuclear structure function F2A(x) has been studied in the Bjorken limit for (l, l) scattering on nuclei in the region of x > 1 and was found to be very sensitive to the information contained in the nucleon spectral function in nuclei, particularly the correlations between momenta and energies in the region of large momenta. Calculations were done in a local density approximation using two d...

The most important part of the order α s corrections to the charm component of the charged-current structure functions F2(x,Q ) and F3(x,Q ) have been calculated. This calculation is based on the asymptotic form of the heavy-quark coefficient functions corresponding to the higher order corrections to the W-boson-gluon fusion process. These coefficient functions which are in principle only valid...
متن کاملSemi-inclusive deep inelastic lepton scattering off complex nuclei
It is shown that in semi-inclusive deep inelastic scattering (DIS) of electrons off a complex nucleus A, the detection, in coincidence with the scattered electron, of a nucleus (A− 1) in the ground state, as well as of a nucleon and a nucleus (A − 2), also in the ground state, may provide unique information on several long standing problems, such as : i) the nature and the relevance of the fina...
متن کاملDeep 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...
