It is informed about the extreme multiplicity studies at 50 GeV in pp interactions. Preliminary multiplicity distributions at U-70 (IHEP, Protvino) energy have obtained for more than 20 charged particles. New elaborated algorithm for the track reconstruction in drift tube tracker and magnetic spectrometer is tested. The collective behavior of secondary particles is manifested in these interactions at the extreme multiplicity region. For the first time we observed ring events in pp interactions at this region. The possibility of the Bose-Einstein condensation detection is discussed.
Key words: extreme multiplicity, collective phenomena, quark-gluon plasma, detectors, track reconstruction
