论文摘要
最近，爱丽丝合作观察到了LHC处鉴定颗粒与培养液的产量的比率的有趣系统行为，这表明它们仅依赖于PP，PPB和PBPB碰撞中带电的粒子多重性。特别是，（多）奇怪粒子相对于亲质的产量，随着多重性的增加和增强的增加是随着陌生含量的增加而发音的。我们将争辩说，这种模式在热模型中自然而然地考虑了奇怪的保护。此外，通过在S-Matrix方法中包括强子相互作用来扩展热模型，爱丽丝数据可以通过在手性交叉温度下的热颗粒屈服来很好地量化，如中央PB-PB碰撞中所示。
Recently the ALICE collaboration has observed an interesting systematic behaviour of ratios of identified particles to pions yields at the LHC, showing that they depend solely on the charged-particle multiplicity in pp, pPb and PbPb collisions. In particular, the yields of (multi)strange particles relative to pions, increases with multiplicity and the enhancement is mode pronounced with increasing strangeness content. We will argue, that such a pattern of arises naturally in the thermal model taking into account exact strangeness conservation. Furthermore, extending the thermal model by including hadron interactions within the S-matrix approach, the ALICE data can be well quantified by the thermal particle yields at the chiral-crossover temperature, as previously found in central Pb-Pb collisions.
