LHC-D Workshop 2008 - Topquark Physik (III)

8 Feb 2008, 12:00 → 9 Feb 2008, 13:30 Europe/Berlin

Bad Honnef

Martin Erdmann, Peter Uwer, Sven Menke, Werner Bernreuther

The main issues will be brief reports on recent progress and discussions of open problems. We propose the following schedule, in the order of the topics below: Friday afternoon: short talks (2 h), discussion (2 h) Saturday morning: short talks (1.5 h), discussion (1.5 h) WG1 (ttbar and single top x-sections) WG2 (top quark mass) WG3 (BSM, top as background) WG1 (NNLO calculations, top decay, charge asymmetry, ...)
