Photoproduction of Negative Pions on Polarized Neutrons in the Region of the Second Resonance

Althoff, K.H. ; Conrad, R. ; Gies, M. ; et al.
Nucl.Phys.B 116 (1976) 253-260, 1976.
Inspire Record 109397 DOI 10.17182/hepdata.35639

A polarized neutron target was used at the Bonn 2.5 GeV Synchrotron to measure the target asymmetry for the reaction γ n↑→ π − p at a fixed photon energy of 700 MeV and pion c.m. angles between 50° and 140°. The pions were detected in a large aperture magnetic spectrometer. The data show a structure which is quite different from the distribution previously measured for the reaction γ p↑→ π + n.

Neutron Fragmentation and Inclusive Charge Exchange in p d and pi+ d Interactions at 195-GeV/c

Eisenberg, Y. ; Haber, B. ; Hochman, D. ; et al.
Phys.Rev.Lett. 38 (1977) 108, 1977.
Inspire Record 109610 DOI 10.17182/hepdata.21024

An excess of negative particles and depletion of positive particles in the backward hemisphere (c.m. system) is observed in π+ and p interactions on neutron target. dσ−dy is compared with pp interactions and the difference is related to the slow-proton spectrum produced in the pn interactions. A neutron fragmentation component is observed and the inclusive charge-exchange probability at the nucleon vertex is found to be about 0.4.

Production of Massive Muon Pairs by 300 and 400-GeV Protons

Kluberg, L. ; Piroue, P.A. ; Sumner, Richard L. ; et al.
Phys.Rev.Lett. 37 (1976) 1451, 1976.
Inspire Record 4051 DOI 10.17182/hepdata.1201

We have observed muon pairs with effective masses in the range 7<~Mμμ<~11 GeV/c2 produced by 300- and 400-GeV protons incident on a Cu target at Fermilab. The production cross section per nucleon, dσdMμμ, for 400-GeV incident protons is found to fall from 1 × 10−36 cm2/(GeV/c2) at Mμμ=7.7 GeV/c2 to 2.7 × 10−38 cm2/(GeV/c2) at Mμμ=11.2 GeV/c2. We find that a significant fraction of the observed direct single muons come from high-mass dimuons.

Polarization Measurements around the Secondary Dip in pip Elastic Scattering

Auer, P. ; Giese, R. ; Hill, D. ; et al.
Phys.Rev.Lett. 37 (1976) 83-84, 1976.
Inspire Record 945158 DOI 10.17182/hepdata.21039

Polarization in π−p elastic scattering, with emphasis in the region around the secondary dip and also θc.m.=90°, has been measured at 2.93 and 3.25 GeV/c. We observe an interesting sign change in this angular region.

Study of A2- --> eta pi- in the Reaction pi- p --> pi- pi- pi+ pi0 p at 11.2-GeV/c

The Bologna-Florence-Genoa-Milan-Oxford-Pavia collaboration Forino, A. ; Gessaroli, R. ; Cartacci, A.M. ; et al.
Nuovo Cim.A 35 (1976) 465, 1976.
Inspire Record 109786 DOI 10.17182/hepdata.37635

The analysis of A2−→ηπ− at 11.2 GeV/c confirms that A2− is essentially produced by natural-parity exchange. In the differential cross-section as a function oft′ there is evidence of the dip at smallt′ values. The branching ratio (A2→ηπ)/(A2→ϱπ) is 0.18±0.05.

Inelastic Diffractive Scattering at FNAL Energies

Ayres, D.S. ; Diebold, Robert E. ; Cutts, D. ; et al.
Phys.Rev.Lett. 37 (1976) 1724, 1976.
Inspire Record 109174 DOI 10.17182/hepdata.21057

Inelastic differential cross sections have been measured for π±p, K±p, and p±p at 140- and 175-GeV/c incident momentum over a |t| range from 0.05 to 0.6 GeV2 and covering a missing-mass region from 2.4 to 9 GeV2. For Mx2 greater than 4 GeV2, the invariant quantity Mx2d2σdtdMx2 was found to be independent of Mx2 at fixed t and could be adequately described by a simple triple-Pomeron form. The values obtained for the triple-Pomeron couplings are identical within statistics for all channels.

Pi+ Electroproduction Above the Resonance Region

Brauel, P. ; Canzler, T. ; Cords, D. ; et al.
Phys.Lett.B 65 (1976) 181-183, 1976.
Inspire Record 109471 DOI 10.17182/hepdata.45245

The reaction e + p → e' + n + π + was studied detecting e' and e' and π + in coincidence at an invariant hadronic mass of 2.19 GeV. The measurements were performed at electron four-momentum transfers squared of Q 2 = 0.06, 0.28, 0.70, and 1.35 GeV 2 in the range of t = ( γ v − π ) 2 between t min and −1.0 GeV 2 . The cross section d 2 σ / dtd was found to be roughly independent of Q 2 for Q 2 > 0.7 GeV 2 and ∥ t ∥ > 0.2 GeV 2 .
