Search for Narrow Dibaryon Resonances via the p -- d Scattering

摘要

Nucleon-nucleon decoupled dibaryons, called Super Narrow Dibaryons (SNDs), were searched for by the pd scattering at Ep =295 MeV over the mass range of 1898 to 1953 MeV The experiment was carried out at the Research Center for Nuclear Physics with a two-arm magnetic spectrometer and a liquid deuterium target A mass resolution of 1 MeV and a low background condition were obtained No resonance structure was observed in the missing mass spectra and the upper limits of the cross section were determined from the data.
