Coming from an hadron collider, how do you see the physics at a lepton collider?
My heart enjoys hadron colliders – the thrill of pushing to the highest energies, the possbility of being the first to glimpse new phenomena, of blazing the first trail through the jungle. But increasingly my head has come to appreciate the beautiful precision that is possible at a lepton collider, for example to measure spins and couplings, and the potential that this has to provide an understanding of the underlying symmetries and laws of nature. How do you see the current role of the UK in the LC R&D? Even from across the Atlantic, it is clear that the UK is playing a strong role in LC R&D. UK physicists are prominent within the Global Design Effort and were very visible at the recent Snowmass meeting. Among other things, they are working on the interaction point design, machine-detector interface issues, and detector development. I am very pleased that my own department hosts one of the leading groups in developing vertex detectors for the ILC through the LCFI project. Which role w
