摘要:

介绍了在IHEP(Protvino)U-70加速器上研究pp相互作用集体现象的最新结果。这是在SVD-2装置上进行的长期实验。我们得到了π介子(玻色-爱因斯坦)凝聚形成的证据。带电π介子角分布中的两个显著峰被解释为夸克对胶子的切伦科夫辐射。在高多重数区,主导效应消失,二次系统各向同性。

英文摘要:

The latest results on the search for collective phenomena in pp interactions at the U-70 accelerator at IHEP (Protvino) are presented. This the long-term experiment has been carried out at the SVD-2 setup. We received the evidence of the pion (Bose-Einstein) condensate formation. Two noticeable peaks in the angular distribution of charged pions are interpreted as Cherenkov radiation of gluons by quarks. The leading effect disappears and the secondary system becomes isotropic in all directions at high multiplicity region.
