Form Factors of the Nucleon in a Selfconsistent Chiral Model

In the present paper we extend the Schwinger model of the nucleon to the inclusion of loop corrections. Starting from a chiral model of nucleon and delta for the mesons $\pi,\rho$ and $A_1$ we extend our nonperturbative sefconsistent regularisation s

Does The 3N-Force Have A Hard Core?

Autor: Eden, J. A., Gari, M. F.

Publikováno v: Phys.Rev.C53:1510-1518,1996

The meson-nucleon dynamics that generates the hard core of the RuhrPot two-nucleon interaction is shown to vanish in the irreducible 3N force. This result indicates a small 3N force dominated by conventional light meson-exchange dynamics and holds fo

A Consistent Meson-Field-Theoretical Description of PP-Bremsstrahlung

Autor: Eden, J. A., Gari, M. F.

Publikováno v: Phys.Rev.C53:1102-1131,1996

A parameter-free and relativistic extension of the RuhrPot meson-baryon model is used to define the dominant isoscalar meson-exchange currents. We compute pp-bremsstrahlung observables below the $\pi-$production threshold using a relativistic hadroni

Meson-Exchange Currents in pp-Bremsstrahlung

Autor: Eden, J. A., Gari, M. F.

Publikováno v: J.Exp.Theor.Phys. 83 (1996) 642-645; Zh.Eksp.Teor.Fiz. 110 (1996) 1168-1173

The long-standing discrepancy between pp-bremsstrahlung data and calculations based on the relativistic impulse approximation current is substantially reduced by the inclusion of the PV$\gamma$ and intermediate-state $\Delta$-resonance iso-scalar mes

Report

Sensitivity of pp-Bremsstrahlung to Meson-Exchange Currents

Autor: Eden, J. A., Gari, M. F.

Publikováno v: Phys.Lett. B347 (1995) 187-192

We present pp-bremsstrahlung cross section calculations at the $\pi$-production threshold to search for kinematics that best differentiate model-dependent descriptions of the NN $t$-matrix and accentuate the contributions of isoscalar meson-exchange
