Description
We have studied the reactions pp->ppπ+π-, K+p->K+pπ+π-, π+p->π+pπ+π-, and π-p->π-pπ+π- at 147 GeV/c using the 30-inch Fermilab hybrid system. All four reactions were detected with the same apparatus and analyzed in the same way. The energy dependence of the channel cross section was found to be Apsup(-0.6)+B for the pp reaction and Ap-1+B for the other three. About 90% of the cross section at 147 GeV/c can be accounted for by either beam or target diffraction. Some of the remaining cross section may come from double Pomeron exchange reactions which we tried to isolate. We have tested the hypothesis of a factorizable Pomeron and our data indicates a violation of this hypothesis. We show that the 3π mass enhancement in the mass region 1.2-1.4 GeV is diffractively produced in the πsup(+-) beam reactions. Four-prong, four-constraint and six-prong, four-constraint cross sections are reported. (orig.)
