Extraction of the strong neutron-proton mass difference from the charge symmetry breaking in p n →d π 0
Abstract We perform a complete calculation of charge symmetry breaking effects for the reaction p n → d π 0 at leading order in chiral perturbation theory. A new leading-order operator is included.Expand

The line shapes of the $Z_b(10610)$ and $Z_b(10650)$ in the elastic and inelastic channels revisited
The most recent experimental data for all measured production and decay channels of the bottomonium-like states $Z_b(10610)$ and $Z_b(10650)$ are analysed simultaneously using solutions of theExpand

Pion--deuteron scattering length in Chiral Perturbation Theory up to order \chi^{3/2}
A complete calculation of the corrections to pion-deuteron scattering length up to order $\chi^{3/2}$ with $\chi=m_{\pi}/M_{N}$ is performed. The calculation includes the dispersive contributions andExpand

Total and differential cross sections of η-production in proton-deuteron fusion for excess energies between Qη = 13 MeV and Qη = 81 MeV
Abstract New data on both total and differential cross sections of the production of η mesons in proton–deuteron fusion to He 3 η in the excess energy region 13.6 MeV ≤ Q η ≤ 80.9 MeV are presented.Expand

Role of the Δ isobar in the reaction NN→NNπ near threshold
Abstract A model calculation for pion production in nucleon–nucleon collisions is presented. Direct production, pion rescattering and contributions from pair diagrams are taken into account. TheExpand

phi meson production in proton proton collisions
The production of $\phi$-mesons in proton-proton collisions is investigated within a relativistic meson-exchange model of hadronic interactions. The experimental prerequisites for extracting theExpand

Analysis of the reactionpp→ppηnear threshold
It is shown that most of the available data on the $pp\to pp\eta$ reaction, including the invariant mass distributions in the $pp\to pp\eta$ reaction recently measured at COSY, can be understood inExpand

Final-state interactions in the process pp → pK + Λ
The possibility to determine the pΛ scattering length from the final-state interaction in the reaction � → pK + Λ is investigated experimentally. From a transversely polarized measurement, the K +Expand

Angular asymmetries in the reactions $$\vec pp \to d\pi ^ + \eta $$ and $$\vec pn \to d\pi ^0 \eta $$ and a0-f0 mixing
AbstractThe reactions pp → dπ+η and pn → dπ0η are of special interest for investigating the a0(980) (JP=0+) resonance in the process NN → da0 → dπη. We study some aspects of those reactions within aExpand

Realistic few-body physics in the dd→απ0 reaction
Abstract We use realistic two- and three-nucleon interactions in a hybrid chiral-perturbation-theory calculation of the charge-symmetry-breaking reaction d d → α π 0 to show that a cross section ofExpand
