Evidence of Pentaquark States from KN Scattering Data?
Motivated by the recent experimental evidence of the exotic B = S = +1 baryonic state Θ (1540), we examine the older existing data on KN elastic scattering through the time delay method. We find positive peaks in time delay around 1.545 and 1.6 GeV in the D03 and P01 partial waves of K N scattering respectively, in agreement with experiments. We also find an indication of the J = 3/2 Θ∗ spin-or...
متن کاملProduction of the pentaquark exotic baryon Ξ 5 in KN scattering : KN → K Ξ 5 and KN → K ∗ Ξ 5
Abstract We investigate the production of the newly found pentaquark exotic baryon Ξ5 in the KN → KΞ5 and KN → KΞ5 reactions at the tree level. We consider the both positiveand negativeparities of the Ξ5. The reactions are dominated by the sand u-channel processes, and it is observed that the resulting cross sections are very much dependent on the parity of Ξ5 and on the type of form factor. We...
متن کاملA Diquark-Triquark Model for the KN Pentaquark
We propose a model for the recently discovered Θ+ exotic KN resonance as a novel kind of a pentaquark with an unusual color structure: a 3c ud diquark, coupled to 3c uds̄ triquark in a relative P -wave. The state has J P = 1/2+, I = 0 and is an antidecuplet of SU(3)f . A rough mass estimate of this pentaquark is close to experiment.

_. -LWe present a comprehensive partial-wave analysis of the; processes rrN ---) &,I3 , KN + &B and TN + &., B in the 3-flavor Skyrme model, with c& an arbitrary pseudoscalar-octet meson and B a h’ octet or g’ decuplet baryon. Overall, we find good, poor, and mixed agreement, respectively, between the model and experiment for these three types of processes. We pay particular attention to assess...
متن کاملSTUDY OF Kn SCATTERING USING THE REACTIONS
An elastic Kn partial wave analysis is presented. It is based on high statistics data for the reactions K*p K*r’n and K*p K*nA* at 13 GeV obtained in a spectrometer experiment performed at SLAC. For each reaction, a t-dependent parametrization of the production amplitudes provides information on both the Kr mass dependence of the production mechanisms and on Kn scattering. Knowledge of the t-de...
