The local nuclear slope B(s,t) = d \over d t (ln dσn (s,t)\over dt) is reconstructed from the experimental angular distributions with a procedure that uses overlapping t-bins, for an energy that ranges from the ISR to the S ppS and the Tevatron. Predictions of several models of (p,p) and ( p,p) elastic scattering at high energy are tested in B(s,t) at small |t|. Only a model with two-components Pomeron and Odderon gives a satisfactory agreement with the (non fitted) slope data, in particular for the evolution of B(s,t) with s as a function of t in pp scattering. This model predicts a similar behavior for pp and pp scattering at small |t|. A detailed confirmation for pp collisions would be expected from RHIC.
