论文摘要
由于最近的理论论点的激励,即扩展字符串可以被认为具有与适当时间成反比的温度,我们研究了在隆德字符串 - 乘坐模型中添加与1/tau成正比的术语添加的后果。然后将张力的晶格值Kappa0〜0.18 GEV^2〜0.9 GEV/FM解释为延迟/平衡极限。这种类型的模型的一般预测是,早期的弦断裂应与更高的陌生(和baryon)分数和较高的片段化<pt>值相关联。应该可以使用档案EE数据集在此类型的情况下提供独立于模型的约束,我们提出了一些简单的关键测量结果。
Motivated by recent theoretical arguments that expanding strings can be regarded as having a temperature that is inversely proportional to the proper time, tau, we investigate the consequences of adding a term proportional to 1/tau to the string tension in the Lund string-hadronization model. The lattice value for the tension, kappa0 ~ 0.18 GeV^2 ~ 0.9 GeV/fm, is then interpreted as the late-time/equilibrium limit. A generic prediction of this type of model is that early string breaks should be associated with higher strangeness (and baryon) fractions and higher fragmentation <pT> values. It should be possible to use archival ee data sets to provide model-independent constraints on this type of scenario, and we propose a few simple key measurements to do so.
