Two narrow peaks at about 1500 and 1800 MeV/c2 are seen in the distributions of invariant mass of the assumed six-pion systems in the final states of pBARNe and pBARHe reactions at 607 MeV/c. In pBARHe-reactions the peaks are seen only in the forward direction, while in pBARNe-reactions they are also seen in the backward direction with momenta near the momentum of the incident antiproton. The peaks could possibly be due to glueballs.

Abstract
Two narrow peaks at about 1500 and 1800 MeV/c2 are seen in the distributions of invariant mass of the assumed six-pion systems in the final states of pBARNe and pBARHe reactions at 607 MeV/c. In pBARHe-reactions the peaks are seen only in the forward direction, while in pBARNe-reactions they are also seen in the backward direction with momenta near the momentum of the incident antiproton. The peaks could possibly be due to glueballs.
