“…At higher energies, avoided level crossing induced by the Λ(1670) resonance entangled with the KΞ Swave threshold is expected as the figure shows (the dynamical coupled channel approach of Ref. [35] is no longer valid at these high energies, while the chiral unitary approach contains the KΞ threshold and generates the Λ(1670) resonance).…”

The spectrum of excited hadrons becomes accessible in simulations of Quantum Chromodynamics on the lattice. Extensions of Lüscher's method allow to address multi-channel scattering problems using moving frames or modified boundary conditions to obtain more eigenvalues in finite volume. As these are at different energies, interpolations are needed to relate different eigenvalues and to help determine the amplitude. Expanding the T -or the K-matrix locally provides a controlled scheme by removing the known non-analyticities of thresholds. This can be stabilized by using Chiral Perturbation Theory. Different examples to determine resonance pole parameters and to disentangle resonances from thresholds are discussed, like the scalar meson f 0 (980) and the excited baryons N (1535)1/2 − and Λ(1405)1/2 − .

“…The DN interaction is derived in close analogy to the meson-exchangeKN model of the Jülich group [21], using as a working hypothesis SU(4) symmetry constraints, and by exploiting also the close connection between the DN andDN systems due to G-parity conservation. More specifically, we use the latter constraint to fix the contributions to the direct DN interaction potential while the former one provides the transitions to channels that can couple to the DN system.…”

Abstract. The DN interaction is studied in close analogy to the meson-exchangeKN potential of the Jülich group using SU(4) symmetry constraints. The model generates the Λ c (2595) resonance dynamically as a DN quasi-bound state. Results for DN scattering lengths and cross sections are presented and compared with predictions based on the Weinberg-Tomozawa term. Some features of the Λ c (2595) resonance are also discussed emphasizing the role of the near-by πΣ c threshold.

We investigate the properties of interference fragmentation functions arising from the emission of two leading hadrons inside the same jet for inclusive leptonnucleon deepinelastic scattering. Using an extended spectator model for the mechanism of the hadronization, we give a complete calculation and numerical estimates for the examples of a proton-pion pair produced with invariant mass on the Roper resonance, and of two pions produced with invariant mass close to the p mass. We discuss azimuthal angular dependence of the leading order cross ,section to point up favorable conditions for extracting transversity from experimental data.
