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* resonances with masses between 1650 MeV/c2 and 1900 MeV/c2 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 → pK 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.
