The result of a search for magnetic charged particles at 70 GeV IPHE proton synchrotron is presented. Using the ferromagnetic trap method the upper limit of the magnetic monopole production cross-section in proton-nucleon collisions was found to be α (95%) ⩾ × 10 −43 cm 2 .

Study of the two-charged-particle final states of 3.9-gev/c pi+- p interactions including a longitudinal-momentum analysis of the one-pion- production channels

We have analyzed the two-prong final states in π+p interactions at 3.9 GeVc. Our result for elastic scattering is σ (elastic) = 6.50±0.1 mb (statistical error only). We find the elastic slope to be 6.61±0.14 (GeVc)−2. We find the elastic forward cross section to be 40.0±1.4 mb(GeVc)2. We have applied a longitudinal-momentum analysis to the one-pion-production channel. We find the cross section for the reaction π++p→π++π0+p to be 2.30±0.06 mb and that for π++p→π++π++n to be 1.45±0.05 mb. For resonance-production cross sections in these channels we find Δ(1236)=0.60±0.07 mb, ρ(760)=0.86±0.06 mb, and diffraction dissociation = 1.69±0.11 mb. We find that we can satisfactorily fit all distributions in the one-pion-production channel without assuming any phase-space production. In the missing-mass channel we observe dominant Δ++(1236) production plus evidence for A2+ production.
