标题： Analysis of Charged-Particle/Photon Observables in Hadronic Multiparticle Production

摘要： 为了分析费米实验室质子对撞机上实验搜索（T-864，MiniMax）中无序手征凝聚（DCC）的联合带电粒子/光子分布数据，我们确定了具有许多优良特性的稳健可观测量，即归一化双变量因子矩的比值。 这些特性包括对许多效率修正和原始π介子产生的建模细节不敏感，并且对DCC的产生敏感，而不是对π介子分成带电和中性种类的通用二项分布划分敏感。 相关的形式理论在MiniMax实验条件的蒙特卡罗模拟中得到了发展和验证。 显示英文摘要

摘要： In order to analyze data on joint charged-particle/photon distributions from an experimental search (T-864, MiniMax) for disoriented chiral condensate (DCC) at the Fermilab Tevatron collider, we have identified robust observables, ratios of normalized bivariate factorial moments, with many desirable properties. These include insensitivity to many efficiency corrections and the details of the modeling of the primary pion production, and sensitivity to the production of DCC, as opposed to the generic, binomial-distribution partition of pions into charged and neutral species. The relevant formalism is developed and tested in Monte-Carlo simulations of the MiniMax experimental conditions.
