dc.descriptionThe modified additive quark model, proposed recently, allows to improve agreement of the standard additive quark model with the data on the $pp, \bar pp, π^{\pm} p, γp$ and $γγ$ total cross-sections, as well as on the ratios of real to imaginary part of $pp$ and $\bar pp$ amplitudes at $t=0$. Here, we extend this model to non forward elastic scattering of protons and antiprotons. A high quality reproduction of angular distributions at 19.4 GeV $\leq \sqrt{s}\leq $ 1800 Gev is obtained. A zero at small $|t|$ in the real part of even amplitude in accordance with a recently proved high energy general theorem is found.
