Strong interaction at storage ring energies

In frontal collisions of protons in the CERN (ISR) storage rings, a 100-fold atomic nucleus density compression has been reached. Does this mean the production of new elementary particles, or does matter become homogeneous? The primary structures at the instant of collision can be reconstructed from observations of the stable fission products. They consist of pure mesonic matter; their properties are independent of both collision energy and type of colliding particle. Their number increases with collision energy. These surface impacts become more frequent with increasing energy. Central impact is recognizable by large deflection, as in Rutherford's scattering experiment. So far, large deflections of electrons and neutrinos, scattered by protons, have been found. Mesons with large deflections have also been found at ISR. These impacts are possibly attributable to point-like structures in the proton. (0 refs).
