Measurement of the coulomb interaction effect in π+π- pairs from the reaction pTa→π+π-X at 70 GeV

Description
Production of π+π- pairs was studied for the reaction pTa→π+π-X at 70 GeV. For the pions with lab momenta from 0.8 to 2.4 GeV/c the two-particle correlation function was measured in the interval of the c.m.s. relative momentum 0≤q≤50 MeV/c. The Coulomb final state interaction for pions produced in a region much smaller than 1/mπα leads to a sharp increase in the yield of π+π- pairs with q<10MeV/c. The effect of the Coulomb interaction has allowed separation of the π+π- pairs with respect to the size of their production region. 25 refs., 8 figs., 6 tabs
