The reaction e + p → e + π0 + p was measured near the one pion threshold, detecting the final electron and proton in coincidence for values of q2 = 0.2, 0.4 and 0.6 GeV2. The slope of the cross section at threshold is determined. The data are compared with those of the e + p → e + π+ + n reaction, measured simultaneously, and with the results of pseudovector Born approximation and with dispersion theoretical calculations. 相似文献

The two photon cascade decay of the 3.7 GeV resonance into the 3.1 GeV resonance has been observed in two nearly independent experiments. The clustering of the photon energies around 160 MeV and 420 MeV observed in the channel 3.7 → (3.1 → μ+μ?) + γγ indicates the existence of at least one intermediate state with even charge conjugation at a mass around 3.52 GeV or 3.26 GeV. 相似文献

The reaction e + p → e′ + π+ + n was measured near the one pion threshold, detecting the final electron and neutron in coincidence for values of q2 = 0.2, 0.4 and 0.6 GeV2. The normalized axial vector form factor to the nucleon was determined from the data within a theoretical framework based on PCAC and current algebra. 相似文献

The reaction γ + Be → e+e? + X was studied with a bremsstrahlung beam of 7.2 GeV maximum energy. For invariant pair masses 1.8 ? Me+e? 2.6 GeV, no evidence for narrow resonance of width smaller than 40 MeV was found. For the mass interval 2.1 ? Me+e? ? 2.6 GeV, we obtained an upper limit of σ · Be+e? < 2 × 10?35 cm2/nucleon (90% confidence level), assuming a production mechanism similar to the θ (1019) meson. 相似文献
