Abstract
Large charged pion pair produced in Double Diffractive Dissociation (DDD) process at high energy is studied with double pomeron (IP) exchange mechanism. Using Donnachie–Landshoff pomeron model we have calculated the cross-section of the process at the energy interval from ISR to LHC when the rapidity of the charged pions is approximately equal to zero. It is shown that this process is the favorite in experiments which could effectively be used to examine Donnachie–Landshoff pomeron model and provide a possibility to check the value of the suppression coefficient .
