| Citation | Robin Marshall has been a consistent innovator in the field of high energy electron-positron annihilation, making many personal contributions. He was the first at the PETRA e+e- collider at DESY to determine the electroweak properties of leptons and then quarks. These papers becoming templates for other experimenters for the next 10 years. He performed the definitive analysis of the world's electron-positron data to produce what are now the "text-book" results for the QCD "fine structure" constant and the fermion electroweak parameters. In 1984, he published a novel method for isolating b quark events and then used the method to measure the b electroweak properties, showing that it belonged to a weak isospin doublet, and hence that the t quark exists. This was one of the most significant physics results from PETRA.
He has been a group leader at RAL for the past 15 years and is currently preparing an experiment at the new electron proton collider HERA at DESY. |
