Proposal to study neutral particle production in 250-GeV p p interactions in the Fermilab 15 foot bubble chamber

PDF Version Also Available for Download.

Description

We propose a small exposure (25K pictures) of the hydrogen-filled FNAL 15-foot bubble chamber to a 250 GeV proton beam. Our main physics objectives are: (1) To study the dependence of neutral particle production ({pi}{sup 0}, K{sup 0}, {Lambda}) on the charged multiplicity in diffractive and non-diffractive processes. (2) To measure integrated correlations (f{sub 2}{sup {+-}0} and f{sub 2}{sup 00}) for neutral pions in a ''clean'' experiment. To make these measurements reliably requires neutral particle detection in both CM hemispheres and the CM symmetry of the pp system. For example, we will determine f{sub 2}{sup 00} to {+-} 0.2.

The event analysis of the neutral secondaries together with the measurement of the slow laboratory protons in pp {yields} p{sub slow} + X for the distinction between diffractive and non-diffractive events will be done in 1/2 year. Further objectives are: (3) To measure differential neutral-charged correlations. (4) To measure multiplicities, spectra and correlations (''inclusive program'') inside the mass M{sub X} in pp {yields} p{sub slow} + X{sup -}.
