Prospects for extended heavy flavour investigations in ALICE using new vertexing methods — •Lukas Layer for the ALICE collaboration — University Heidelberg — GSI Darmstadt
A Large Ion Collider Experiment (ALICE) is a dedicated heavy-ion experiment at the LHC that focuses on the study of the hot and dense strongly interacting medium created in Pb-Pb collisions, the so-called Quark-Gluon Plasma (QGP). Heavy quarks (charm and beauty), that are only produced in the initial hard scattering processes, constitute an important way to probe features of the QGP. Due to the typically short decay length for charmed hadrons (cτ ≈ 150 µ m) and beauty hadrons (cτ ≈ 500 µ m) powerful vertexing algorithms are needed in order to reach the precision required to measure these decays and to distinguish the contributions from charm and beauty. For this a new vertexing package "KFParticle", that is based on Kalman Filter mathematics, is tested and the prospects for new heavy flavour measurements are investigated.
