Nonexistence of a ηNN quasibound state

چکیده
We have solved the Faddeev equations for ηd elastic scattering using realistic separable interactions for the N N and coupled ηN-πN subsystems. We found that including explicitly the pion channel in the integral equations drastically reduces the attraction that is present in the system. As a consequence, the existence of a ηN N quasibound state is excluded by the modern ηN amplitude analysis.

Quasibound states at thresholds in multichannel impurity scattering
We investigate the threshold behaviour of transmission resonances and quasibound states in the multichannel scattering problems of a one-dimensional (1D) time-dependent impurity potential, and the related problem of a single impurity in a quasi-1D wire. It was claimed before in the literature that a quasibound state disappears when a transmission zero collides with the subband boundary. However...
متن کاملZero-energy bound or quasibound states and their implications for diatomic systems with an asymptotic van der Waals interaction
Using an l-insensitive quantum defect theory, we derive a set of universal properties, both spectral and scattering, that are shared by diatomic systems with an asymptotic van der Waals interaction and having a zero-energy bound or a quasibound state of angular momentum lb . The Cs dimer is studied as an example. Systems that are close to having a bound or a quasibound state at the threshold ar...
متن کاملExact calculations of a quasibound state in the K̄ K̄ N system
Dynamically exact calculations of a quasibound state in the K̄K̄N three-body system are performed using Faddeev-type AGS equations. As input two phenomenological and one chirally motivated K̄N potentials are used, which describe the experimental information on the K̄N system equally well and produce either a oneor two-pole structure of the (1405) resonance. For the K̄K̄ interaction separable potentia...
متن کاملOverview of K̄-Nuclear Theory and Phenomenology Search for Narrow Quasibound States
Experimental evidence for K̄-nuclear quasibound states is briefly reviewed. Theoretical and phenomenological arguments for and against deep K̄-nucleus potentials which might allow for narrow quasibound states are reviewed, with recent calculations suggesting that ΓK̄ ≥ 100 MeV for BK̄ ≤ 100 MeV. Results of RMF calculations that provide a lower limit of ΓK̄ ∼ 50± 10 MeV on the width of deeply bound s...
متن کاملREACTION DYNAMICS. Spectroscopic observation of resonances in the F + H2 reaction.
Photodetachment spectroscopy of the FH2(-) and FD2(-) anions allows for the direct observation of reactive resonances in the benchmark reaction F + H2 → HF + H. Using cooled anion precursors and a high-resolution electron spectrometer, we observe several narrow peaks not seen in previous experiments. Theoretical calculations, based on a highly accurate F + H2 potential energy surface, convincin...
