Determination of N* amplitudes from associated strangeness production in p+p collisions

Abstract

We present the first determination of the energy-dependent production amplitudes of N${}^{\ast }$ resonances with masses between 1650 MeV/c${}^2$ and 1900 MeV/c${}^2$ for an excess energy between $0$ and $600$ MeV. A combined Partial Wave Analysis of seven exclusively reconstructed data samples for the reaction p+p $\to pK\Lambda$ measured by the COSY-TOF, DISTO, FOPI and HADES collaborations in fixed target experiments at kinetic energies between 2.14 and 3.5 GeV is used to determine the amplitude of the resonant and non-resonant contributions.
