Study of the ø meson by e+e− annihilation into charged K mesons and tests of vector dominance models
J.C. Bizot,Y. Chatelus,J. Jeanjean,D. Lalanne,H.Nguyen Ngoc,J. Perez-Y-Jorba,P. Petroff,F. Richard,F. Rumpf,D. Treille +9 more
TL;DR: In this article, the e+e− → o reaction was measured by its K+K− decay mode and the 3π decay mode of the o mesons, and then compared the whole Orsay results to theoretical predictions.

TL;DR: In this article, negative results on backward production via baryon exchange of exotic non-strange mesons are presented, and the upper limits obtained on cross sections for exotic meson production X → N N π, N Nπ, 4π are lower than the ϱ − backward production cross section in the π − p→p ϱ− reaction.

TL;DR: In this article, backward meson production in the reaction π−p → pfπ+π−π−− at 9 GeV/c and 12 GeV /c incident π − momenta, from an experiment performed at the CERN Ω Spectrometer using a fast proton (pf) trigger device, was analyzed.

Quantum electrodynamics test by e+e− scattering at 2 × 510 MeV
J.E. Augustin,B. Delcourt,J. Jeanjean,D. Lalanne,H.Nguyen Ngoc,J. Perez-Y-Jorba,P. Petroff,F. Richard,F. Rumpf,D. Treille +9 more
TL;DR: The absolute cross-section σ of Bhabha scattering e + e − → e+ e − has been measured at the total center of mass energy of 1020 MeV to test quantum electrodynamics as discussed by the authors.

TL;DR: In this paper, an unsuccessful search has been made for the reaction π − p → p F p n to find an M− state in pn corresponding to the M0 (2020) and M0(2204) found earlier in the baryon exchange process π−p → Δ0 (or N0 (1520)) + M0.
