Abstrakt: No experiment has found convincing evidence for free quarks [1, 2]. A possible explanation for this non-observation in accelerator experiments is that their cross-section for interaction with matter is much larger than those of hadrons [3], and hence they are scattered and/or absorbed by material between their production point and the detector. We have examined this possibility by exposing 1/4 mm diameter steel balls near an intersection point of the CERN SPS $$p\bar p$$ collider beams. These balls have been subsequently examined for the presence of fractional charge, using the Rutherford Laboratory room temperature magnetic levitation system [4]. None of the 60 balls tested to date shows evidence of fractional charge. [ABSTRACT FROM AUTHOR]
