Various phenomena in particle physics suggest that two quarks in the proton can form diquarks - bound two quark objects inside the nucleons. The crucial tests of the diquark models are given by the processes with high momentum transfers. This short review tries to summarize the present status of the siquark hypothesis in large transverse momentum (PT) collisions at high energies. The data, mainly from the Split Field Magnet detector at eh Intersecting Storage Rings at CERN, show abundant proton production at medium values of PT with properties which cannot be explained by the standard parton models.
