Central exclusive diffractive production of two-pions from continuum and decays of resonances in the Regge-eikonal model
Abstract
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 f0(500), f0(980) and f2(1270) couplings to Pomeron, and also 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.
