π−p→π0n differential cross-sections have been measured in the region of small 4-momentum transfer at 40 GeV/c incident momentum. The experiment performed at the IHEP 70 GeV accelerator makes use of a hodoscope γ-spectrometer. Thet- dependence of the cross-section points to a dominance of the spin-flip amplitude.

Study of the reaction $\pi^- p \rightarrow \omega^0 n$ at momenta 20 to 50 GeV/c

Bolotov, V.N. ; Isakov, V.V. ; Kakauridze, D.B. ; et al.
Phys.Lett.B 53 (1974) 217-220, 1974.
Inspire Record 1388799 DOI 10.17182/hepdata.27929

The mass spectrum of 3γ states produced in π−p collisions has been studied. A peak corresponding to ωo→πoγ decay in the π−p→ωon reaction was selected. The measurements were performed at the IHEP accelerator at momenta 21, 25, 32.5, 40 and 48 GeV/c. The reaction cross section decreases with the momentum in a power form (∼P−2.4) The differential cross section follows exponential t-dependence, exp (bt). The scattering cone shrinks slowly with the energy increase.

Results are presented on the reaction K − p → K̄ o n for momenta above 20 GeV/ c . Events were identified by precise measurement of the opening angle in the decay K o → π + π − without using a magnetic field. The cross-section is described by a power energy dependence.

NEUTRAL MESONS WHICH DECAY INTO 4 pi0

The Serpukhov-Brussels-Los Alamos-Annecy(LAPP) collaboration Alde, D. ; Binon, F.G. ; Bricman, C. ; et al.
Phys.Lett.B 198 (1987) 286-291, 1987.
Inspire Record 250768 DOI 10.17182/hepdata.30106

Data on the 4π 0 decay mode of mesons have been obtained in a search for glueballs performed at the CERN SPS with the GAMS-4000 multiphoton spectrometer. A new tensor glueball candidate X(1810) appears as a clear peak in the 4π 0 mass spectrum. The 4π 0 decay of G(1590) is also observed. The measured value of BR(G→4 π 0 )/BR(G→ ηη )=0.8±0.3 further supports the glueball assignment of this scalar particle. The rate decay of f(1270) into 4π 0 has been measured: BR(f→4 π 0 ) = (3±1)×10 −3 .

A narrow meson which decays into ηη is observed in 38 GeV/ c π − p collisions at large momentum transfer. The experiment has been performed at the Serpukhov accelerator with the GAMS-2000 spectrometer. The mass of this new meson is (1755 ± 8) MeV, its width is less than 50 MeV. Its spin-parity is J PC =0 ++ or less probably 2 ++ .

Negative pion charge exchange scattering on protons in the momentum range 20-50 gev/c

Nucl.Phys.B 73 (1974) 365-386, 1974.
Inspire Record 94656 DOI 10.17182/hepdata.32247

Differential cross sections for charge exchange π − p → π 0 n have been measured for momenta up to 50 GeV/ c . The cross section falls as a power of energy. The forward scattering cone shrinks with increasing energy. The cross section for charge exchange at zero angle drops with momentum as P −0.81±0.05 . The charge exchange cross section in the region of the second maximum decrease as P −2.8±0.1 . The ϱ trajectory is described by a linear function α ( t ) = 0.56 + 0.97 t in the interval 0 < − t -<1.5 (GeV/ c ) 2 .

A Study on pi- Charge Exchange Reactions on Nuclei at 48-GeV/c

Bolotov, V.N. ; Isakov, V.V. ; Kakauridze, D.B. ; et al.
Nucl.Phys.B 85 (1975) 158-164, 1975.
Inspire Record 90365 DOI 10.17182/hepdata.32132

The charge-exchange cross sections were measured for π − on Li, C, Al and Cu nuclei at momentum 48 GeV/ c . By comparing the data obtained for nuclei with those for hydrogen under the same conditions the effective numbers of protons are defined. The conclusion is made that η 0 mesons are absorbed in nuclei weaker then π 0 . The total cross section of η 0 interactions with the nucleon is determined to be σ tot ( η 0 N) = 15 ± 5 mb in agre ement with the quark model.

Cross sections for p ̄ p → n ̄ n at 25 and 35 GeV/ c have been measured. The cross sections decrease with increasing momentum as 1/ P 2 . A narrow peak is observed in the momentum transfer interval 0 ⩽ − t ≲ 0.02 (GeV/ c 2 in the differential cross sections. Neither ϱ nor A 2 exchange contribute to the process in the investigated energy range.

Differential cross sections for π − p → η 0 n, η 0 → 2 γ have been measured from 20 to 50 GeV for four-momentum transfers − ≲ 3 (GeV/ c ) 2 . The cross sections decrease as a power of momentum and the forward scattering cone shrinks slowly. The parameters of the A 2 trajectory, which is considerably non-linear, have been determined.
