DOUBLE DIFFRACTIVE DISSOCIATION PROCESS P-BAR)-]X-P+X-P((P))(OVER-BAR)+PI(+)+PI(-) AT HIGH-ENERGY AND THE POMERON MODEL OF DONNACHIE-LANDSHOFF(P((P)OVER)

Large p(T) charged pion pair produced in Double Diffractive Dissociati on (DDD) process at high energy is studied with double pomeron (IP) ex change mechanism. Using Donnachie-Landshoff pomeron model we have calc ulated the cross-section of the process at the energy interval from IS R 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 pomero n model and provide a possibility to check the value of the suppressio n coefficient N-2.
