Central exclusive diffractive production of two pions from continuum and resonance decay in the Regge-eikonal model

Abstract

Calculations of the central exclusive diffractive production (CEDP) of two pions via continuum and resonance mechanisms are presented in the Regge-eikonal approach. Data from STAR, ISR, CDF and CMS are analysed and compared with theoretical descriptions. The preliminary extraction of $$f_0(500)$$ f 0 ( 500 ) , $$f_0(980)$$ f 0 ( 980 ) and $$f_2(1270)$$ f 2 ( 1270 ) couplings to pomerons and the $$\rho $$ ρ meson contribution from the photoproduction mechanism to the CEDP cross-section are considered. We show possible nuances and problems of calculations and prospects of investigations at current and future hadron colliders.
