Sept. 517/2 With a linear trajectory this required that the pomeron has a slope of 0·64 GeV−2. Several factors however have led to the abandoning of the association of the pomeron with the f0. 1973 B. H. Bransden et al. Fund. Particles ix. 181 At present it does not seem that the Pomeron corresponds to a physical particle and it probably should be thought of as a device to bring diffraction scattering into the same exchange framework as other reactions. 1994 Science 24 June 1844/3 Invented in the 1960s.., the pomeron was set aside later when quarks were identified as the proton's internal components. 1998 Physical Rev. D. 58 074008-1 The Pomeron, in a first approximation, is a single Reggeized gluon plus a ‘wee-parton’ component that compensates for the color and particle properties of the gluon.
