The role of the meson–exchange current correction to the nuclear charge operator is studied in electron scattering processes involving the excitation of medium and heavy nuclei to energies up to the quasi–elastic peak. The effect of these contributions in the quasi–free electron scattering process is a reduction of at most a 3% in the longitudinal response at the energy of the peak, a value whi...
متن کاملNuclear Saturation with in-Medium Meson Exchange Interactions
We show that the assumption of dropping meson masses together with conventional many-body e ects, implemented in the relativistic Dirac-Brueckner formalism, explains nuclear saturation. We use a microscopic model for correlated 2 exchange and include the standard many-body e ects on the in-medium pion propagation, which initially increase the attractive nucleon-nucleon (NN) potential with densi...
متن کاملEffective operator contributions to the oblique parameters
We present a model and process independent study of the contributions from non-Standard Model physics to the oblique parameters S, T and U. We show that within an effective lagrangian parameterization the expressions for the oblique parameters in terms of observables are consistent, while those in terms of the vector-boson vacuum polarization tensors are ambiguous. We obtain the constraints on ...
متن کاملMeson exchange models for Meson production
The production of mesons in nucleon–nucleon collisions is reviewed from the viewpoint of the meson–exchange picture. In the first part various possible production mechanisms and their relative importance are discussed. In addition, general features of meson production are described. In the second part special emphasis is put on pion production. Implications of chiral perturbation theory are dis...
متن کاملNuclear-structure aspects of nonanalog pion double charge exchange.
ined. t|)j'e consider the nonanalog ground-state to ground-state (T=0 to T=2) transitions on a variety of nuclear targets. The reaction model, which assumes that double charge exchange is driven by a m+p-meson —mediated„633 nucleon interaction, reproduces the energy dependence and shape of the empirical cross section for all the (m+, m ) transitions examined. The magnitude of the cross section ...
