Pion reactions with few-nucleon systems
نویسنده
چکیده
We report about the recent results for sand p-wave pion production in NN → NNπ within effective field theory and discuss how the charge symmetry breaking in pn → dπ 0 can be used to extract the strong contribution to the neutron-proton mass difference.

On the Nucleon Renormalization in Many Nucleon Problems Due to Pionic Degrees of Freedom+
Conceptual problems of unified two-nucleon force models are discussed. The force models are based on the pion-nucleon vertex and attempt a description of the nucleon-nucleon interaction below and above pion threshold. The conceptual problems arise from the nucleon renormalization due to pionic degress of freedom. Keeping channels with a single pion only no renormalization procedure can be given...
متن کاملPion reactions on two–nucleon systems
We review recent progress in our understanding of elastic and inelastic pion reactions on two nucleon systems from the point of view of effective field theory. The discussion includes πd scattering, γd → πnn, and NN → NNπ. At the end some remarks are made on strangeness production reactions like γd → KΛN and NN → KΛN .
متن کاملπ-Photoproduction on the deuteron via ∆-excitation using the Lorentz Integral Transform
The Lorentz Integral Transform method (LIT) is extended to pion photoproduction in the ∆resonance region. The main focus lies on the solution of the conceptual difficulties which arise if energy dependent operators for nucleon resonance excitations are considered. In order to demonstrate the applicability of our approach, we calculate the inclusive cross section for π-photoproduction off the de...
متن کاملThe role of the pion cloud in the interpretation of the valence light-cone wavefunction of the nucleon
The pion cloud renormalises the light-cone wavefunction of the nucleon which is measured in hard, exclusive photon-nucleon reactions. We discuss the leading twist contributions to high-energy exclusive reactions taking into account both the pion cloud and perturbative QCD physics. The nucleon’s electromagnetic form-factor at high Q is proportional to the bare nucleon probability Z and the cross...
متن کاملChiral Symmetry and Three-Nucleon Forces
After a brief review of the role three-nucleon forces play in the few-nucleon systems, the chiral-perturbation-theory approach to these forces is discussed. Construction of the (nominal) leadingand subleading-order Born terms and pion-rescattering graphs contributing to two-pion-exchange three-nucleon forces is reviewed, and comparisons are made of the types of such forces that are used today. ...
