Pion pion correlations at low relative momentum produced in the reactions proton-proton going to proton-proton(positive pion, negative pion)(n) with n = 2,3,4,5,6
Abstract
We have measured low relative momentum correlations between like sign pions produced in the reactions pp $\to$ pp($\pi\sp+,\pi\sp{-})\sp{\rm n}$ with n ranging from 2 to 6. The data sample consisted of $0.93\times10\sp6$ fully reconstructed exclusive interactions, with incident proton momentum of 27.5 GeV/c, recorded by experiment E766 at the AGS in Brookhaven National Laboratory. By parametrizing the correlation with a function of Q$\sp2$ representing the dynamics of the reaction and the correlation itself, it was shown that the Q$\sp2$ scale does not depend on the final state multiplicity and has a value of 1.08 fermi. The "strength" of the correlation does depend on multiplicity. For negative pions the "strength" is 26% larger than for positive pions.
