Electro-strong interaction and high Q^2 events at HERA

Abstract

A previously proposed unified field theory of electro-strong interactions requires two scales of length within hadrons, $\sim 10^{-15}m$ and $\sim 10^{-18}m$ 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 $Q^2\ge 30,000$ $(Gev/c{)}^2$. The collider is currently being upgraded. This will permit a clearer test to be carried out.
