Abstract

Results on exclusive double diffraction dissociation in (N π) and (N ππ) final states are reported for neutron-neutron interactions at √ s= 26.4 GeV and for the proton-neutron interactions at √ s= 37.2 GeV. The data have been obtained at the CERN intersecting storage rings using split field magnet detector with proton-deuteron and deuteron-deuteron colliding beams. Factorization is shown to be verified to a very high degree in both mass- and t-differential cross-sections. The data confirm the previously observed rise in the proton-proton double diffractive cross-section as a function of c.m. energy.
