Abstract
Quasi-elastic scattering with central dipion cluster production is studied in π+ p andK + p interactions at 250 GeV/c. The cross section of double pomeron exchange is obtained as σDPE(π+ p →π+(π+π−)p)=24 ±5 µb and σDPE(K + p→K +(π+π−)p)=19 ±5 µb. The low energy pomeron-pomeron cross section is estimated for the first time.
