Evidence for the omega pi pi decay modes of the a2 and omega(1675)

Diaz, J. ; Dibianca, F.A. ; Fickinger, W.J. ; et al.
Phys.Rev.Lett. 32 (1974) 260-264, 1974.
Inspire Record 94695 DOI 10.17182/hepdata.21339

We present evidence for the decay A20→ωπ+π0 with a branching ratio Γ(A2→ωππ)Γ(A2→ρπ)=0.28±0.09 and for the decay ω(1675)→ωπ+π− with a branching ratio Γ(ω(1975)→ωπ+π−)Γ(ω(1675)→ρπ)=0.47±0.18. Evidence is given for an intermediate B(1235)π state in the ω(1675) decay.

Boson States in the Reaction pi- p --> pi- pi- pi+ p with Leading pi+ Meson at 25-GeV/c

The Serpukhov-CERN collaboration Antipov, Yu.M. ; Busnello, R. ; Damgaard, G. ; et al.
Nucl.Phys.B 119 (1977) 45-59, 1977.
Inspire Record 109772 DOI 10.17182/hepdata.35516

The reaction π − + p → π − + π − + π + + p at 25 GeV/ c was studied in the mass region M 3 π ⩾ 1.8 GeV with leading π + . The mass spectrum of the π + π − system shows peaks corresponding to the ϱ 0 , f and g 0 resonances and an enhancement around 1.9 GeV. Evidence is presented for a J P = 3 + s-wave g 0 π − state (A 4 ) similar to the ϱ 0 π − (A 1 ) and fπ − (A 3 ) threshold enhancements.

Analysis of the Reaction K- p --> K- pi- pi+ p at 40-GeV/c

The CERN-Serpukhov Boson Spectrometer Group collaboration Antipov, Yu.M. ; Ascoli, G. ; Busnello, R. ; et al.
Nucl.Phys.B 86 (1975) 381-402, 1975.
Inspire Record 90643 DOI 10.17182/hepdata.32087

The reaction K − p → K − π − π + p has been measured at 25 and 40 GeV/ c at the Serpukhov Proton Accelerator. The production cross section at 25 and 40 GeV/ c as a function of momentum transfer and K ππ mass is presented, and results of the partial-wave analysis of the K ππ system yielding information about Q(1300), K ∗ (1400) and L(1770) mesons are discussed.
