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...
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 ...
متن کاملΣ-nuclear spin-orbit coupling from two-pion exchange
Using SU(3) chiral perturbation theory we calculate the density-dependent complexvalued spin-orbit coupling strength UΣls(kf ) + iWΣls(kf ) of a Σ hyperon in the nuclear medium. The leading long-range ΣN interaction arises from iterated one-pion exchange with a Λ or a Σ hyperon in the intermediate state. We find from this unique long-range dynamics a sizeable “wrong-sign” spin-orbit coupling st...
متن کاملEnergy dependence of pion double charge exchange
Pion double charge exchange ~DCX! on nuclear targets has been extensively studied, both experimentally and theoretically, throughout the last two decades. Because at least two nucleons must be involved in the process, the study of DCX is a natural tool for exploring nucleon-nucleon correlations. In the course of these studies at low energies, a prominent peak in the (p,p) cross section in the n...
متن کاملCharge-Symmetry Breaking and the Two-Pion-Exchange Two-Nucleon Interaction
Charge-symmetry breaking in the nucleon-nucleon force is investigated within an effective field theory, using a classification of isospin-violating interactions based on power-counting arguments. The relevant charge-symmetry-breaking interactions corresponding to the first two orders in the power counting are discussed, including their effects on the 3He − 3H binding-energy difference. The stat...
