The Higgs boson!
I am a member of the ATLAS collaboration since 2004. In July 2012 we found a new boson at a mass of 125 GeV that is a candidate for the long sought after Higgs boson! My interest is in the final state where the Higgs boson decays into two tau leptons which decay themselves hadronically. Establishing the decay of the new boson into fermions directly is important to characterise the particle. Tracking and vertexing is of particular interest for me in this decay mode as tau leptons have a relatively long lifetime. A better understanding in this area will help to improve the mass resolution.
The silicon tracker of ATLAS is another of my research interests. I already built endcap modules for the present SCT. A luminosity upgrade of ATLAS is planned and for this a completely new tracker is required. We are investigating radiation hard silicon for this upgrade. Cooling of silicon staves is another aspect of my research for the ATLAS upgrade.
I am also a member of the D0 experiment at the Tevatron at Fermilab. I have done a search for the Higgs boson decaying into a pair of W-bosons at this experiment. The Tevatron experiments were the first ones to show that there is no (additional) Higgs boson in the mass region around 160 GeV.
