Abstract

The πNN vertex function is determined from $d σ d t$ for pn → np and $p p → n n$ at 8 GeV/c in the interval 0 < − t < 0.1 GeV². A “regularor mass” of 3.5m_π=488 MeV is found, corresponding to an “extension” of 0.40 fm of the πNN vertex. The resulting OPE potential is discussed.

The role of the Δ in nuclear physics
2002, Physics Report
We review the properties of Δ, and the role it plays in Nuclear Physics. We try to assess what has been ascertained up to now, and what remains to be clarified about this hadron, which represents the outstanding structure in the medium-energy pion–nucleon interaction. We consider the free Δ first, with particular emphasis on those aspects which may give information on the internal hadron structure, such as the isospin mass splittings in the Δ multiplet, and the electromagnetic fingerprints of deviation from spherical symmetry. We then discuss the N–Δ interaction, both under the point of view of meson-exchange models, and under a microscopic quark-model perspective. In so doing, we review the present status of the meson–nucleon and meson–Δ coupling constants and form factors, whose knowledge is a prerequisite for a description of nuclei in terms of effective hadronic degrees of freedom. We discuss also the coupled-channel approach to the NN–NΔ system, and how it compares with relativistic treatments grounded on Quantum Field Theory. We then consider light nuclei, where the percentage of Δ components in the nuclear wave function, and Δ contributions to meson-exchange currents can be studied in a quantitative way, with a minimum of uncertainties due to nuclear-structure effects. Finally, we discuss Δ propagation in finite nuclei and nuclear matter. To this end, we try to give an update presentation of classical subjects, such as the effective Δ interaction in the nuclear environment, medium effects and quenching phenomena, where Δ-hole excitations and nuclear-structure effects are strictly intertwined.
Charge-exchange np scattering
1997, Nuclear Physics A
We have studied the charge-exchange p(n,p)n reaction for neutron beam momenta from 0.605 to 105 GeV/c. The t-matrix is constructed using a one-pion-exchange plus rho-exchange transition potential. The differential cross sections are calculated in the distorted wave Born approximation and are compared with the available experimental data. The data on the t-distributions upto 20 GeV/c are reproduced well within our model at all values of the momentum transfer t.

The deuteron asymptotic D-state as a probe of the nucleon-nucleon force
1983, Nuclear Physics, Section A
A critical discussion is given of the various contributions to the asymptotic D/S ratio from the πNN interaction. Particular emphasis is laid on the analysis of contributions from 2π exchange, the dependence on the πNN form factor, and on the πN coupling constant, so as to assess quantitatively the model dependence of the result. From this analysis, significant restrictions are deduced on the shape of the πNN form factor and, in quark bag models, the value of the quark bag radius. The results of previous theoretical approaches for the D/S ratio and quadrupole moment are shown to obey a universal and linear relation, when expressed in reduced units so as to compensate for small differences in effective range and πN coupling constant. The quadrupole moment is also quantitatively analyzed in detail. Its value is proved to be an accurate and almost model-independent consequence of the experimental D/S ratio (apart from relativistic and meson-exchange corrections) in agreement with observations. In the comparison with experiments, a critical survey of the relevant experimental data is given. In particular, a considerably improved value for the quadrupole moment is deduced.
The pair current in the constituent quark model

How do the nucleon anomalous magnetic moments behave in nuclear matter?
1981, Nuclear Physics, Section A
This paper investigates three questions: (i) What is the structure of the nucleon anomalous magnetic moments in the chirally symmetric, renormalizable σ + ω model? (ii) Is the usual assumption of pion-current dominance (no nucleon recoil) justified in field-theoretic models? (iii) How does the presence of symmetric, infinite nuclear matter at normal density affect the anomalous moments? In answer to (i) it is found that the sigma and omega mesons play an important role in restoring the balance in isoscalar and isovector moments for isolated nucleons. The answer to (ii) is “no”. A rough calculation of the effect of nuclear matter yields, for the effective moment of a particle near the top of the Fermi sea, k_p(eff) ∼-1.5 nm, k_p(eff) ∼- −2.2 nm.
