Abstract

We present results from MiniMax (Fermilab T-864), a small test/experiment at the Tevatron designed to search for the production of disoriented chiral condensate (DCC) in $p - p ˉ$ collisions at $s = 1.8$ TeV in the forward direction, $\sim 3.4 < I^\cdot <\sim 4.2$ . Data, consisting of $1.3 \times 1 0^{6}$ events, are analyzed using the robust observables developed in an earlier paper. The results are consistent with generic, binomial-distribution partition of pions into charged and neutral species. Limits on DCC production in various models are presented.
