Search for fractionally charged particles produced in proton-proton collisions at the highest ISR energy
The results of an experiment to search for quarks at the CERN ISR, at a total centre-of-mass energy square root s=62.2 GeV, are reported. The experiment was sensitive to fractionally charged particles with 0.035e<or= mod Q mod <or=0.67e, beta =v/c>or=0.1 and masses up to 26 GeV/c/sup 2/. Th...

| description | The results of an experiment to search for quarks at the CERN ISR, at a total centre-of-mass energy square root s=62.2 GeV, are reported. The experiment was sensitive to fractionally charged particles with 0.035e<or= mod Q mod <or=0.67e, beta =v/c>or=0.1 and masses up to 26 GeV/c/sup 2/. The 90% confidence level on the ratio 'quark flux /charged flux' is 1.78.10/sup -9/ for Q=+(1/3)e and 1.05.10/sup -9/ for Q=-(1/3)e. These values hold true for production processes with transverse momenta p/sub perpendicular to / approximately=0.4 GeV/c. (15 refs). |
