Today at ICHEP CMS and ATLAS showed their first top candidate events. They see events in both semileptonic and dileptonic channels, with muons and electrons in all combination. Here is one event display in the mu+jets+missing energy channel provided by CMS:
The reconstructed top mass from this event is around 210 GeV, while the latest measurement of the top quark mass from the Tevatron is 173.1 GeV. This is very surprising - naively, one would expect the American top quarks to be heavier ;-)
