Ido Mussche, ATLAS The master thesis of Ido will focus on the offline issues related to the fully hadronic decay of top meson pairs. He will start with event reconstruction and estimate the signal to background ratio after 1 year of low luminosity running. A detailed comparison with the semi leptonic channel is part of this task.

Menelaos Tsiakiris, ATLAS The master thesis of Menelaos will focus on the trigger issues related to the fully hadronic decay of top meson pairs. First he will investigate the jet trigger chain and characterize the behavior with a fully hadronic top sample at each trigger level (turn-on curves, pre-scales, etc.). Next, he will study the selection efficiencies of the jet triggers, including the cross correlation with semi leptonic trigger schemes. This cross correlation will enable us to estimate trigger efficiencies from real data.

Sander Klous, ATLAS & Physics Data Processing I am focusing my research on two main topics: high energy physics and data processing. My projects basically aim to unify these interests. The analysis of fully hadronically decaying top-antitop Higgs events requires integration of the entire data processing chain, from data acquisition system and trigger to offline analysis. Successful completion of this project would enable us to significantly increase the complexity of our analysis tools in the near future.
