The experimental data for pp and {bar p}p at {radical}s = 53 GeV shows the difference between the differential cross sections in the dip region. This prompted the need for a crossing-odd amplitude even at this energy. Further support to this idea was provided by the order of magnitude rise of the measured pp differential cross section in the dip region as we go from ISR to CERN collider energies. In order to overcome the difficulty to explain these phenomena, Gauron et al used the idea of an odderon in addition to the pomeron and explained the then available data for pp and {bar p}p. Dynamical origin to the idea of an odderon was later provided by Islam. He has pointed out that, if the nucleon consists of a core of valence quarks surrounded by a cloud of quark-antiquark pairs, then in elastic scattering an odderon amplitude occurs when the cores interact by exchanging a J = 1, C = {minus}1, u{bar u} + d{bar d} state and the cloud undergoes maximal diffraction scattering. The model has recently been modified by these authors so as to fit the very recent data of {bar p}p at 546 GeV and make predictions at 1.8 TeV. The same idea was also used by Barnbard et al to explain the pp and {bar p}p data , Jankovszky et al have also fitted the data for p ({bar p}) p by employing the odderon in conjunction with the dipole pomeron. In this paper the authors will compare the results of these models with the most recent measurements at tevatron and also compare them with those of other models.
