The reaction π−p→η′η′n has been studied atpπ=37 GeV/c. Total of 14 events of this reaction have been selected. It has been shown that in the effective mass spectrum of the η′η′ system the events are concentrated mainly near the reaction threshold, which might be caused by the decayX(1910)→η′η′. The reaction cross-section has been evaluated: σ(π−p→η′η′n)=110±40 nb.

Study of a Possible Exotic $\phi \pi^0$ State With a Mass of About 1.5-{GeV}/$c^2$

New data have been obtained on a resonance in the ϕπ 0 system, the C meson, which is formed in the π − p → ϕπ 0 n charge-exchange reaction. The experiment has been performed at the Serpukhov 70 GeV accelerator. The mass and the width of the resonance are measured to be M =1480±40 MeV , Γ =130±60 MeV . The production cross section is determined at a π − momentum of 32.5 GeV / c : σ ( π − p → Cn )· BR ( C → ϕπ 0 )=40±15 nb . The C(1480) meson has an isospin I =1 and spin-parity J PC =1 − − . It is strongly coupled to the ϕπ 0 channel and is considered as a possible exotic meson.

STUDY OF D (1285) ---> K+ K- pi0 DECAY

Results on the study of D(1285)→K + K − π 0 -decay are presented. The K + K − effective mass spectrum is measured with statistics which are by an order of magnitude higher than in the previous data. From the analysis of the differential spectrum d N d M KK (in the framework of the δ-dominance model) the δ-meson effective width is Γ δ >180MeV/ c 2 at √ s =1 GeV/ c 2 , which means a strong coupling of the δ-meson with hadrons.

Inclusive and Semiinclusive rho0 Production in pi- p Interactions at 15-GeV/c

We have done an inclusive study of ϱ 0 production in π − p interactions at 15 GeV/ c . Evidence for two different production mechanisms, in addition to the known quasi two-body processes, is presented: production of ϱ 0 's in the central region of rapidity similar to the “pionization” region seen in the inclusive studies of pions; and forward production in the beam dissociation region of rapidity. Cross sections and rapidity distributions for the ϱ 0 are given inclusively and by topology, and the results are compared with similar studies at other energies and with other incident particles. Results are also presented for the semi-inclusive reaction π − p → p ϱ 0 + X − and the exclusive final state p π − ϱ 0 .
