| Popis: | Odderon is the $C$-odd amplitude that does not fall (or decrease very slowly) with energy. The expected amplitude is small and mainly real. Therefore, extracting it from the data on top of a much larger $C$-even contribution is challenging. The only chance is to consider the very low $|t|$ region of Coulomb nuclear interference or the diffractive dip region. Here we perform the analysis of elastic scattering $pp$ and $\bar pp$ data at low momentum transfer $|t| < 0.1$ GeV$^2$ within large collider energy interval $\sqrt s = 50$ GeV $-$ 13 TeV in order to evaluate quantitatively the possible Odderon contribution. We use the two-channel eikonal model, which naturally accounts for the screening of the Odderon amplitude by the $C$-even (Pomeron) exchanges. Comment: 4 pages, 1 figure.
