A search for fractionally charged particles at the CERN intersecting storage rings

Final results of a search for fractionally charged particles at the CERN Intersecting Storage Rings are reported. Several independent scintillation counter, multiwire proportional chamber telescopes simultaneously sampled c.m. production angles from 0 degrees to 90 degrees . The experiment was sensi...

description Final results of a search for fractionally charged particles at the CERN Intersecting Storage Rings are reported. Several independent scintillation counter, multiwire proportional chamber telescopes simultaneously sampled c.m. production angles from 0 degrees to 90 degrees . The experiment was sensitive to particles of electric charge in the range 0.1e< mod Q mod <0.8e, with velocities greater than 0.25c and with masses up to, in principle, 47 GeV/c/sup 2/. No such particles were observed among the products of 1.2*10/sup 10/ proton- proton interactions at s=2830 GeV/sup 2/. The cross section limit for the production of quark-antiquark pairs of charge mod Q mod =/sup 1 ///sub 3/e or /sup 2///sub 3/e in the reaction pp to ppqq, at s=2830 GeV/sup 2/, is sigma <or approximately=8*10/sup -35/ cm/sup 2/ for quark masses up to approximately 20 GeV/c/sup 2/. (30 refs).
