    "abstract": "The probability distribution in $R$, the proportion of neutral pions to all\npions emitted in heavy ion collisions in certain kinematic regions, has been\nsuggested as a signal of a disoriented chiral condensate (D$\\chi$C). Here we\nnote that the signature can be greatly enhanced by making suitable cuts in the\ndata. In particular, we consider reducing the data set such that the $k$ pions\nwith lowest $p_T$ are all neutral. We find that, given such cuts, $\u003cR \u003e$ can be\nsubstantially different from 1/3. For example, for a single D$\\chi$C domain\nwithout contamination due to incoherently emitted pions, $\u003cR\u003e$ is 3/5 given the\npion with lowest $p_T$ is neutral, and 5/7 given the two pions with lowest\n$p_T$ are both neutral, etc.. The effects of multi-domain D$\\chi$C formation\nand noise due to incoherent pion emission can be systematically incorporated.\nPotential applications to experiments and their limitations are briefly\ndiscussed.",
