Indication of an excited hyperon state in pp collisions with ANKE at COSY-Jülich

The reaction pp→pK+Y has been studied with the ANKE spectrometer at COSY-Jülich in order to investigate heavy hyperon production. The missing mass spectra MM(pK+) have been analyzed and compared with Monte Carlo simulations. Indications for a hyperon resonance Y0∗(1480) have been found.
