Two-pion-exchange contributions to the pp→ ppπ0 reaction

Our previous study of the near-threshold pp→ ppπ0 reaction based on a hybrid nuclear effective field theory is further elaborated by examining the momentum dependence of the relevant transition operators. We show that the two-pion-exchange diagrams give much larger contributions than the one-pion-exchange diagram, even though the former is of higher order in the Weinberg counting scheme. The re...

Full Determination of Transition Matrix Elements in the D( P, Pp)n Reaction

It is shown that in the d(p, pp)n reaction with a colinear geometry and the two outgoing protons in a singlet state, the only two independent T-matrix elements can be determined from spin correlation experiments. These matrix elements are strongly dependent on the deuteron helicity amplitudes, which are expected to vanish for 1.4f m −1 < p < 1.7f m −1 .

Resonances and final state interactions in the reaction pp → pK +

A study of the strangeness production reaction pp→pK + Λ for excess energies of ǫ ≤ 150 MeV, accessible at high-luminosity accelerator facilities like COSY, is presented. Methods to analyze the Dalitz plot distribution and angular spectra in the Jackson and helicity frames are worked out and suitable observables for extracting information on low lying resonances that couple to the KΛ system and...

Three - pair final - state interaction in the pp → pp η reaction close to threshold 1 )

We present a three-body formalism describing the final-state interaction effects in the pp → ppη reaction close to threshold. We derive a three-body enhancement factor devised in such a way that all three pair-wise interactions are regarded on equal footing. The enhancement factor is obtained by expanding the three-particle wave function in hyperspherical harmonics. It has been shown that close...

Two - nucleon knockout contributions to the 12 C ( e , e ′ p ) reaction in the dip and ∆ ( 1232 ) regions

The contributions from 12C(e, epn) and 12C(e, epp) to the semi-exclusive 12C(e, ep) cross section have been calculated in an unfactorized model for two-nucleon emission. We assume direct two-nucleon knockout after virtual photon coupling with the two-body pion-exchange currents in the target nucleus. Results are presented at several kinematical conditions in the dip and ∆(1232) regions. The cal...
