abstract

We report properties of $\Lambda$ and $\Sigma$ hyperon resonances formed in $K^-$ induced reactions. Special emphasis is laid on the analysis of the three-body final states $2\pi^0\Lambda$ and $2\pi^0\Sigma$ and of the quasi-two-body final states $\pi\Lambda(1520)$, $\bar K\Delta(1232)$, $\pi\Sigma(1385)$, $\bar K^*N$, and $\omega\Lambda$. We give pole positions of $\Lambda$ and $\Sigma$ hyperon resonances and transition residues from the $K^-p$ initial to various final states as well as Breit-Wigner masses and widths and decay branching ratios. Twenty resonances and "bumps" reported in the Review of Particle Physics are not required in our fits, evidence for five new resonances is reported. The observed mass spectrum is compared to the spectrum calculated in the Bonn quark model. Three spin doublets, six $\Lambda$ hyperons, are tentatively assigned to the SU(3) singlet system.

  1. Low-lying $\Lambda$ and $\Sigma$ resonances studied with the forward $K^*$ productions off the proton induced by a high-momentum $\pi$ beam

    hep-ph 2026-05 unverdicted novelty 7.0 of 10

    Forward pion-induced K-star production can turn a possible new 3/2+ Sigma resonance plus the known Sigma(1385) into one peak in the pion-lambda mass spectrum, with angular distributions separating the two.

  2. Extraction of $\sigma_{TT}$ for Proton, Neutron, Deuteron and $^3$He from Quasi-real Photon Scattering

    hep-ex 2026-07 conditional novelty 5.0 of 10

    Quasi-real electroproduction data extrapolated to Q²=0 give σ_TT for p, n, d and ³He, with larger neutron/deuteron Δ(1232) strength than real-photon data and better isospin consistency.

  3. Resolving the $\Delta(1232)$ partial width anomaly: Complex pole residue is not a fundamental resonance property

    hep-ph 2025-05 conditional novelty 5.0 of 10

    Using an improved Breit-Wigner model, the paper argues that complex pole residues are amplitude-level quantities, and shows how multi-resonance interference can make the Delta(1232) partial width appear to exceed its ...
