Testing the nature of the Λ(1520) resonance in proton-induced production
نویسنده
چکیده
The Λ(1520) resonance has been recently studied in a unitarized coupled channel formalism with πΣ(1385), KΞ(1530), K̄N and πΣ as constituents blocks. We provide a theoretical study of the predictions of this model in physical observables of the pp → pKKp and pp → pKππΛ reactions. In particular, we show that the ratio between the ππΛ and K−p mass distributions can provide valuable information on the ratio of the couplings of the Λ(1520) resonance to πΣ(1385) and K̄N that the theory predicts. Calculations are done for energies which are accessible in an experimental facility like COSY at Jülich or the developing CSR facility at Lanzhou.

Comparative Regge analysis of Λ , Σ 0 , Λ ( 1520 ) and Θ + production in γp , πp and pp reactions
Comparative Regge analysis of Λ, Σ 0 , Λ(1520) and Θ + production in γp, πp and pp reactions Abstract. Using the Quark-Gluon Strings Model – combined with Regge phenomenology – we perform a comparative analysis of Λ, Σ 0 , Λ(1520) and Θ + production in binary reactions induced by photon, pion and proton beams on the nucleon. We find that the existing experimental data on the γp → K + Λ differen...

Recent studies within the framework of chiral unitary theory produce the Λ(1520) resonance, among several others, as a dynamically generated resonance from the interaction of the baryon decuplet and the meson octet. The Λ(1520) qualifies as a quasibound state of πΣ(1385) and this has repercussion in some observable quantities. In the present work we show that the γp → K+K−p reaction has a sizea...

The discrepancy between Θ photoproduction on proton vs. deuteron can be resolved if the photon couples much more strongly to KK than to KK̄ as indicated by the experimentally observed asymmetry between γp → Λ(1520)K and γn → Λ(1520)Ks. Significant signal-background interference effects can occur in experiments like γN → K̄Θ which search for the Θ as a narrow I = 0 resonance in a definite final st...

The internal structure of the Λ(1405) hyperon has remained an unresolved mystery in hadron physics for decades. Observed as a resonance in Σπ just below the N-K threshold , it is the first excited Λ state; yet the nature of this resonance, where it belongs in the hierarchy of hyperons, and some of its basic properties, remain unsettled. In previous experiments, the invariant mass spectrum (line...

In this paper, we have investigated the kaon-deuteron interaction at an incident momentum of 1 GeV/c using the relativistic and non-relativistic Faddeev method for different phenomenological and chiral potentials. By calculating the π∑ invariant mass spectra on different particle channels, we have shown that the trace of Λ(1405) resonance is visible in such spectra. In the present work, the st...
