ABC resonance in the (p)over-right-arrowp -> ppX(0) reaction, or is the ABC effect made of colored quark cluster configurations? art. no. 014001

The reaction (p) over right arrowp-->ppX was studied at two energies (T-p=1 520 and 1805 MeV) and at several angles between 0 degrees and 17 degrees in the laboratory. The analyzing powers and cross sections of the ABC enhance ment production were measured in the missing mass (M(pio)less than or equal toM(x)less than or equal toM(eta)). Several substructures were observed at different angles and both energies. Substructures at M-x approximate to 31 0 and 350 MeV were systematically extracted. Substructures in the higher ma ss range 400 less than or equal toM(x) less than or equal to 500 MeV were o bserved but their masses were less stable. These substructure masses have b een associated with q(2)-(q) over bar (2) (and q(3)-(q) over bar (3)) confi gurations, allowing a new assumption for the ABC effect description, as bei ng colored multiquark clusters.
