Alberica Toia is Professor of Experimental Nuclear Physics at Goethe University Frankfurt, with a joint appointment with GSI since Octorber 2013.
She studied in Milano, but got her Bachelor at Niels Bohr Institute, Copenhagen, and later the Master in Milano. She did her PhD in Giessen, working on the HADES experiment at GSI. She was Post-Doc at Stony Brook University, working on the PHENIX experiment at
ALICE (A Large Ion Collider Experiment) is a dedicated heavy-ion detector to exploit the unique physics potential of nucleus-nucleus interactions at LHC energies (CERN). Our aim is to study the physics ofstrongly interacting matter at extreme energy densities, where the formation of a new phase of matter, the quark-gluon plasma, is expected. The existence of such a phase and its properties are key issues in QCD for the understanding of confinement and of chiral-symmetry restoration. For this purpose, we are carrying out a comprehensive study of the hadrons, electrons, muons and photons produced in the collision of heavy nuclei.
The ALICE group in Frankfurt is involved into the construction of the central barrel of ALICE, in particular the Time Projection Chamber (TPC) and the Transition Radiation Detector (TRD). In addition, fast and intelligent online data processing systems are needed to pick out interesting signals from a huge background of conventional events. For this purpose, a High Level Trigger (HLT) system for ALICE is being developed.
Our group is taking part in the First-Level Event Selector (FLES) to select events online with trigger-criteria that require partial or full event reconstruction within novel concept of '4D tracking', dictated by the continuous readout, in order to separate interactions even in cases where they partially overlap in time.
