The OPERA Experiment – Neutrino Oscillation Search — •Annika Hollnagel — Universität Hamburg, Institut für Experimentalphysik, Luruper Chaussee 149, 22761, Hamburg
The primary goal of the OPERA long-baseline neutrino oscillation experiment is the first direct detection of νµ→ ντ oscillations.
The hybrid OPERA detector consists of a target made from lead and photo emulsions, providing micrometric resolution, and electronic detector parts for on-line readout. It is located in the LNGS underground laboratory, at a baseline of 730 km from the SPS at CERN, where the νµ CNGS beam is produced.
The measurement of ντ appearance relies on the detection of the decay of τ leptons which are created in ντ charged current reactions. Data acquisition started in 2008, and numerous beam-induced events have been recorded, including the observation of a first ντ candidate event in 2009.
In this talk, the current status of the oscillation analysis will be presented.
