REAL PART OF THE $\bar pp$ ELASTIC SCATTERING AMPLITUDE AT $\sqrt{s} = 546\, {\rm GeV}$

In order to get an accurate determination of the real part of the ppBAR elastic scattering amplitude at square root s = 546 GeV, the Genoa-Palaiseau-Roma-Valencia collaboration plans to take experimental data on d-sigma/dt in the Coulomb interference region. We present detailed theoretical predictions for this cross-section. These predictions can be compared directly with the forthcoming data.
