Calculations of central exclusive diffractive di-pion continuum production are presented in the Regge–eikonal approach. Data from ISR, STAR, CDF and CMS were analyzed and compared with the ...theoretical description. We also consider theoretical predictions for LHC, possible nuances and problems of calculations and prospects of investigations at present and future hadron colliders.
In the light of the latest data by the LHCf collaboration of the LHC on leading neutrons spectra it is possible to obtain total pion–proton cross sections in the TeV energy region. In this work the ...exact extraction procedure is shown. Final results for the pion–proton cross section are collected at several different values of the colliding energy and compared with some popular theoretical predictions. The errors of the results are estimated.
We consider the general theoretical framework to study exclusive double diffractive events (EDDE). It is a powerful tool to explore the picture of the

interaction. Basic kinematical and dynamical ...properties of the process, and also normalization of parameters via standard processes like the exclusive vector meson production (EVMP), are considered in detail. As an example, calculations of the cross-sections in the model with three pomerons for the process

Some predictions for the LHC at 13 TeV are also presented. We briefly discuss possible nuances, problems and prospects for investigations of this process at present and future hadron colliders.
