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

R.A. Ryutin
摘要
Calculations of central exclusive diffractive production (CEDP) of two pionsvia continuum and resonance mechanism are presented in the Regge-eikonalapproach. Data from STAR, ISR, CDF and CMS were analysed and compared withtheoretical description. Preliminary extraction of $f_0(500)$, $f_0(980)$ and$f_2(1270)$ couplings to Pomeron, and also $\rho$ meson contribution fromphotoproduction mechanism to the CEDP cross-section are considered. We showpossible nuances and problems of calculations and prospects of investigationsat present and future hadron colliders.
