摘要

介绍了在IHEP（Protvino）U-70加速器上寻找质子相互作用集体现象的最新结果。这个长期实验是在SVD-2装置上进行的。我们的研究针对的是一个高多样性区域，在该区域可以预测一系列集体现象。我们收到了一个π介子（玻色-爱因斯坦）凝聚体形成的证据。我们在带电π介子的角分布中观察到了两个明显的峰值，这两个峰值被夸克和其他现象解释为胶子的切伦科夫辐射。

Collective Behavior of Secondary Particles in the Region of high Multiplicity in pp Interactions at 50 GeV/c

The latest results on the search for collective phenomena in proton interactions at the U-70 accelerator at IHEP (Protvino) are presented. This long-term experiment has been carried at the SVD-2 setup. Our study was aimed at a high multiplicity region where the series of collective phenomena is predicted. We have received an evidence of the formation of a pion (Bose-Einstein) condensate. We have observed two noticeable peaks in the angular distribution of charged pions interpreted as Cherenkov radiation of gluons by quarks and others phenomena.
