Baryonic resonances close to the (K)over-barN threshold: The case of Lambda (1405) in pp collisions
We present an analysis of the Lambda(1405) resonance produced in the reaction p Schwerionenforschung (GSI). The two charged decay channels Lambda (1405) -> Sigma(+/-) + pi). Wefind a total production cross...

Strange baryon resonances in pp collisions measured with HADES
We present an analysis of the hyperons Lambda(1405) and Sigma(1385)(+) for p+p reactions at 3.5 GeV kinetic beam energy. The data were taken with the High Acceptance Di-Electron Spectrometer (HADES). A Lambda(1405)...

Lambda*(1405)-matter: Stable or unstable?
A recent suggestion by Akaishi and Yamazaki (2017) [3] that purely-Lambda*(1405 that the binding energy per Lambda*, B/A, saturates for A greater than or similar to 120 with values of B/A considerably below 100 MeV, implyin...

pK(+)Lambda final state: Towards the extraction of the ppK(-) contribution
has been motivated by the assumption that in p + p collisions the Lambda(1405) resonance can act as a doorway to the formation of the kaonic bound states. The statusThe reaction p(@3.5 GeV) + p -> p + Lambda + K+ ...

On the stability of Lambda(1405) matter
A hypothesis of absolutely stable strange hadronic matter composed of Lambda(1405) baryons, here denoted Lambda(star), is tested within many-body calculations the Lambda(star)Lambda(star) interaction compa...

Production of Sigma(+/-)pi(-/+)pK(+) in p plus p reactions at 3.5 GeV beam energy
We study the production of Sigma(+/-)pi(-/+)-pK(+) particle quartets in p + p reactions at 3.5 GeV kinetic beam energy. The data were taken with the HADES experiment at GSI. This report evaluates the contribution of resonances like Lambd...

Testing chiral unitary models for the Λ(1405) in K+πΣ photoproduction
We adopt a novel formalism for the low-energy analysis of the gamma p -> K+ pi Sigma photoproduction reaction, outlined recently in [P. C. Bruns, arXiv:2012.11298.], to calculate the pi Sigma invariant mass distributions in the Lambda(14...
