Within a quasipotential framework a relativistic analysis is presented of the deuteron current. Assuming that the singularities from the nucleon propagators are important, a so-called equal time approximation of the current is constructed. This is applied to both elastic and inelastic electron scattering. As dynamical model the relativistic one boson exchange model is used. Reasonable agreement is found with a previous relativistic calculation of the elastic electromagnetic form factors of the deuteron. For the unpolarized inelastic electron scattering effects of final state interactions and relativistic corrections to the structure functions are considered in the impulse approximation. Two specific kinematic situations are studied as examples.Comment: (19 pages in revtex + 15 figures not included, available upon request.) report THU-93-10

We reanalyze the scaling properties of inclusive quasielastic electron scattering from 12 C by subtracting from the data the effects of two-particle emission. A model of relativistic meson-exchange currents (MEC) is employed within the mean field theory of nuclear matter, with scalar and vector potentials that induce an effective mass and a vector energy to the nucleons. A new phenomenological quasielastic scaling function is extracted from a selection of the data after the subtraction of the 2p-2h contribution. The resulting superscaling approach with relativistic effective mass (SuSAM*) can be used to compute the genuine quasielastic cross section without contamination of the 2p-2h channel that can then be added separately to obtain the total quasielastic plus two-nucleon emission response.

Semiempirical formula for electroweak response functions in the two-nucleon emission channel in neutrino-nucleus scattering

A semiempirical formula for the inclusive electroweak response functions in the two-nucleon emission channel is proposed. The method consists in expanding each one of the vector-vector, axial-axial, and vector-axial responses as sums of six subresponses. These correspond to separating the meson-exchange currents as the sum of three currents of similar structure and expanding the hadronic tensor as the sum of the separate contributions from each current plus the interferences between them. For each subresponse, we factorize the coupling constants, the electroweak form factors, the phase space, and the delta propagator, for the delta-forward current. The remaining spin-isospin contributions are encoded in coefficients for each value of the momentum transfer, q. The coefficients are fitted to the exact results in the relativistic mean field model of nuclear matter, for each value of q. The dependence on the energy transfer ω is well described by the semiempirical formula. The q-dependency of the coefficients of the subresponses can be parametrized or can be interpolated from the provided tables. The description of the five theoretical responses is quite good. The parameters of the formula, the Fermi momentum, number of particles, relativistic effective mass, vector energy, the electroweak form factors, and the coupling constants, can be modified easily. This semiempirical formula can be applied to the cross section of neutrinos, antineutrinos, and electrons.
