| الوصف: | Calculations of central exclusive diffractive production (CEDP) of two pions via continuum and resonance mechanism are presented in the Regge-eikonal approach. Data from STAR, ISR, CDF and CMS were analysed and compared with theoretical description. Preliminary extraction of $f_0(500)$, $f_0(980)$ and $f_2(1270)$ couplings to Pomeron, and also $\rho$ meson contribution from photoproduction mechanism to the CEDP cross-section are considered. We show possible nuances and problems of calculations and prospects of investigations at present and future hadron colliders. Comment: 13 pages, 12 figures. arXiv admin note: substantial text overlap with arXiv:1910.06683. All the figures with datasets are changed due to more exact calculations. Some minor changes in the text, which describes the figures (ISR, CDF) and in conclusions. Corrected typos in Fig. 9 (nb/GeV is changed to mub/GeV) |
