Abstract

We present the first determination of the energy-dependent amplitudes of N^⁎ resonances extracted from their decay in KΛ pairs in p+p→pK⁺Λ reactions. A combined Partial Wave Analysis of seven data samples with exclusively reconstructed p+p→pK⁺Λ events measured by the COSY-TOF, DISTO, FOPI and HADES Collaborations in fixed target experiments at kinetic energies between 2.14 to 3.5 GeV is used to determine the amplitude of the resonant and non-resonant contributions into the associated strangeness final state. The contribution of seven N^⁎ resonances with masses between 1650 MeV/c² and 1900 MeV/c² for an excess energy between 0 and 600 MeV has been considered. The Σ–p cusp and final state interactions for the p–Λ channel are also included as coherent contributions in the PWA. The N^⁎ contribution is found to be dominant with respect to the phase space emission of the pKΛ+ final state at all energies demonstrating the important role played by both N^⁎ and interference effects in hadron–hadron collisions.
