Inequality for Backward Electron - and Muon - Nucleon Scattering at High Momentum Transfer
نویسنده
چکیده
From a sum rule for backward up scattering, valid only in the limit of large four-momentum transfer q2, we obtain an inequality for backward e-p inelastic scattering which depends ,upon the commutator of space components of isospin currents. Given chiral U(6) X U(6) current algebra, the total backward scattering at fixed large q2. is predicted to be at least as great as that from a point Dirac particle with charge f e/2.

A resolution of the missing charge problem in quasielastic electron scattering
At high momentum transfer jqj > 1GeV, the longitudinal response in quasielastic electron scattering is well reproduced by the free Fermi gas model. This suggests the suppression of the Z-graph contributions in elementary electron-nucleon scattering in nuclear medium. Therefore we develop the relativistic model in which those contributions are partially suppressed. The suppression rede nes the r...
متن کاملElectron Quasielastic Scattering at High Energy from 56 Fe , What Suppression ?
Quasielastic electron scattering (e, e ′) from 56 Fe is calculated at large electron energies (2-4 GeV) and large three momentum transfer (0.5-1.5 GeV/c). We use a relativistic mean-field single particle model for the bound and continuum nucleon wavefunctions based on the σ − ω model and we include the effects of electron Coulomb distortion in the calculation. The calculations are compared to h...

متن کاملNucleon Momentum Distributions from a Modified Scaling Analysis of Inclusive
Inclusive electron scattering from nuclei at low momentum transfer (corresponding to x ≥ 1) and moderate Q is dominated by quasifree scattering from nucleons. In the impulse approximation, the cross section can be directly connected to the nucleon momentum distribution via the scaling function F (y). The breakdown of the y-scaling assumptions in certain kinematic regions have prevented extracti...

It is shown that owing to a dominance of np−pair transfer mechanism of backward elastic p Hescattering for incident proton kinetic energies Tp > 1 GeV the cross section of this process is defined mainly by the values of the Faddeev component of the wave function of He nucleus, φ(q23,p1), at high relative momenta q23 > 0.6GeV/c of the NN-pair in the S0− state and at low spectator momenta p1 ∼ 0−...
