چکیده
In p+p, d+Au, and Au+Au collisions at √ sNN = 200 GeV with the STAR detector at RHIC, Σ(1385) → Λ+ π were measured using two techniques; threeparticle mixing and a hybrid mixing technique. We present results from both of these methods and compare the invariant mass spectra and the backgrounds.

The Σ(1385) analysis and the current status of pentaquark search with the STAR detector are reported. The corrected pT spectra and the yields of the Σ±(1385) and their antiparticles in the most central Au+Au as well as elementary p+p collisions are presented. A comparison of the 〈pT 〉 of observed particles suggests a similar behavior for particles with mass greater than 1.2 GeV in p+p and Au+Au...

We study the Λ(1520) resonance in a coupled channel approach involving the πΣ(1385), KΞ(1530), ¯ KN and πΣ channels. Implementing unitarity in coupled channels, we make an analysis of the relative importance of the different mechanisms which contribute to the dynamical structure of this resonance. From experimental information on some partial wave amplitudes and constraints imposed by unitarity...

The pole structure of the low energy ππ scattering amplitudes is studied using a proper chiral unitarization method combined with crossing symmetry and the low energy phase shift data. It is found that the σ pole position is at M σ = 470 ± 50M eV , Γ σ = 570 ± 50M eV. The existence of the virtual state pole in the IJ=20 channel is reconfirmed. Various threshold parameters are estimated and are ...

We explore how chiral-symmetry constraints on weak-interaction matrix elements suggest the existence of an intermediate-state σ in several different weak-interaction processes. Particular attention is directed toward recent evidence for a σ within three-body nonleptonic weak decays. The existence of a broad scalar-isoscalar ππ resonance near 500-600 MeV, the σ, has long been controversial. Afte...

We study the decay channels of the Λ(1520) in a nuclear medium and find a sizable change of the order of factor five of the width of this hyperon at normal nuclear matter density. The mass shift of the Λ(1520) is moderate. The change of resonance properties in the nuclear medium is a field that captures permanent attention, and basic symmetries can be tested through medium modification of parti...
