Inspire Record 1407540 DOI 10.17182/hepdata.70207

The rr- + p- n + rr0 charge-exchange scattering and the rr- + p- n + 1J ( 1J- 2y) reaction were investigated in 1.55-4.5 BeVIc region in a 17-liter propane-xenon bubble chamber. The total cross sections of both reactions were measured in this region. The angular distributions of the rr0 mesons in the charge-exchange reaction were obtained. The backward exchange-scattering cross sections du( rr- + p- n + rr 0 )ldQ were estimated.

Inspire Record 1407579 DOI 10.17182/hepdata.70213

The elastic scattering of 300-Mev negative pions from hydrogen was studied with the aid of a hodoscopic system with pulse-fed counters. Equation (1) gives the angular distribution for the elastic scattering under the hypothesis that the fundamental contribution to the scattering comes from the S and P waves.

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

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.

High-precision Measurements of piP Elastic Differential Cross Sections in the Second Resonance Region

The EPECUR collaboration Alekseev, I.G. ; Andreev, V.A. ; Bordyuzhin, I.G. ; et al.

Inspire Record 1323450 DOI 10.17182/hepdata.67659

Cross sections for pi+-p elastic scattering have been measured to high precision, for beam momenta between 800 and 1240 MeV/c, by the EPECUR Collaboration, using the ITEP proton synchrotron. The data precision allows comparisons of the existing partial-wave analyses (PWA) on a level not possible previously. These comparisons imply that updated PWA are required.

Measurement of pi- p ---> pi0 n in the vicinity of the eta threshold

Phys.Rev.C 72 (2005) 015205, 2005.

Inspire Record 688197 DOI 10.17182/hepdata.25171

We report a new measurement of the differential cross section for π−p→π0n from pπ=649 to 752 MeV/c, which is around the opening of the η channel (685 MeV/c). Our data support the main features of the π−p charge-exchange differential cross sections generated by the SAID πN partial-wave analysis. The opening of the η channel has a clear effect on the shape of the excitation function for dσ(π−p→π0n), which is most noticeable in the backward direction.

The ITEP-PNPI collaboration presents the results of the measurements of the spin rotation parameter A in the elastic scattering of positive and negative pions on protons at P_beam = 1.62 GeV/c. The setup included a longitudinally-polarized proton target with superconductive magnet, multiwire spark chambers and a carbon polarimeter with thick filter. Results are compared to the predictions of partial wave analyses. The experiment was performed at the ITEP proton synchrotron, Moscow.
