Universe Colloquium: Massive gluons in top-quark pair production

by Susanne Westhoff ((Universität Mainz))

Wednesday 8 Jun 2011, 16:30 → 18:00 Europe/Berlin

seminar room (basement) (Cluster building, Garching)

At the Tevatron experiment, an asymmetry in top-quark pair production has been observed: Top quarks tend to move in the direction of the incident proton rather than in the direction of the antiproton. Explaining this phenomenon requires an extension of the standard model of particle physics by a new particle. Massive gluon-like objects are good candidates, even though their features are constrained by other observables. The LHC has the potential to probe the properties of top quarks at high energies. In particular, it will shed light on the hypothesis of massive gluons in top-quark pair production.
The talk is followed by a wine & cheese event!
