Physics Colloquium

"LHeC: Sub-Attometric lepton-quark Physics?"

Presented by John Dainton, University of Liverpool

Wednesday, December 20, 2006, 3:30 pm — Large Seminar Room, Bldg. 510

Deep-inelastic lepton-hadron scattering has been a cornerstone in the development of our fundamental understanding of matter. We now have a picture of matter at the sub-nucleon level of resolution approaching 10-18 m which is built on point-like leptons and quarks as conceived in the non-abelian field theories Quantum Chromodynamics (QCD) and (Quantum Flavour Dynamics (QFD). To go further requires TeV-energy scale interactions. The LHC at CERN will provide a stupendous laboratory for probing the next level of sub-structure, that is of new physics, in quark-quark, gluon-quark, and gluon-gluon interactions. Taking advantage of the hadron beams - proton and heavy ions - at the LHC, a hitherto unparalleled opportunity emerges to probe direct lepton-quark interactions at TeV-energy in many different ways at an electron/positron hadron collider LHeC. The outcome of a first evaluation of this opportunity in terms of physics and of implementation is presented, thereby setting a horizon for precision lepton-quark physics with sub-attometric resolution.
