  A previously proposed unified field theory of electro-strong interactions
requires two scales of length within hadrons, $\sim10^{-15}m$ and
$\sim10^{-18}m$ respectively, and the onset of new phenomena at the shorter
scale. Studies at the HERA electron-proton collider at the shorter scale have
revealed a possible excess of high-transverse momentum events, as expected,
with $Q^2 \geq 30,000$ $(Gev/c)^2$. The collider is currently being upgraded.
This will permit a clearer test to be carried out.
