Electron-muon coincidences in proton-proton collisions at the CERN Intersecting Storage Rings
In an experiment carried out at the CERN Intersecting Storage Rings with a highly selective electron spectrometer system and a magnetized iron filter to detect muons, the authors have observed 32+or-16 dilepton events of the type p+p to mu /sup +or-/+e/sup -or+/+... The integrated luminosity of the...

description | In an experiment carried out at the CERN Intersecting Storage Rings with a highly selective electron spectrometer system and a magnetized iron filter to detect muons, the authors have observed 32+or-16 dilepton events of the type p+p to mu /sup +or-/+e/sup -or+/+... The integrated luminosity of the experiment was (2.0+or-0.1)*10/sup 37/ cm /sup -2/, and the over-all detection efficiency 0.14+or-0.07. Interpreting this signal as due to charmed meson-pair production, the authors estimate a model-dependent acceptance of 6.5*10/sup -5/ per event, and a cross-section sigma (p+p to D+D+...)=(18+or-9) mu b, with a scale uncertainty of 50% due to the detection efficiency. (9 refs). |
