| Citation | John Dainton is distinguished for his leading contribution to the understanding of the fine structure of matter, through the high energy scattering of leptons and photons off protons.
During the 1970s his work led to the experimental identification of partonic effects at large momentum transfer in photon-proton interactions. Subsequently his analysis of data in terms of photon structure revealed how the latter could be beautifully interpreted in terms of QCD, the gauge theory of the strong interaction.
Since 1986, he has played a leading role in the experimental physics program of the electron?proton collider experiment H1. As Physics Co-ordinator of H1 (1996?97) he was responsible for the publication of innovative measurements concerned with the structure of the proton, photon and their interactions at an unprecedented small scale. One of his seminal contributions has been in developing a first understanding of hadronic interactions (the so-called 'Regge parametrisation') in terms of a calculable gauge theory QCD.
In 1997, he was appointed as Spokesman of the international collaboration H1, a position in which he leads the experiment and directs its scientific output. |
