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.
