CDF Results Raise Questions on Quark Structure

An article to appear in the February 9 issue of Science describes
results contained in a paper submitted to Physical Review Letters by
the 450-member Collider Detector at Fermilab collaboration. The
CDF paper reports results that appear to be at odds with predictions
based on the current theory of the fundamental structure of matter.
The paper, submitted January 21, reports the collaboration's
measurement of the probability that the fundamental constituents of
matter will be deflected, or will "scatter," when very high energy
protons collide with antiprotons, according to CDF spokesmen
William Carithers and Giorgio Bellettini.
