Soft and Hard Probes in p-Pb Collisions with the ALICE Experiment — •Annika Passfeld for the ALICE collaboration — Institut für Kernphysik, Westfälische Wilhelms-Universität Münster, Germany

In contrast to Pb-Pb collisions, the formation of a hot and dense medium as the quark-gluon plasma is not expected in p-Pb. Therefore, the effects of cold nuclear matter can be studied in isolation in this collision system. Furthermore p-Pb collisions bridge the multiplicity gap between pp and peripheral Pb-Pb collisions. Studying particle production in this region can improve the understanding of the underlying particle production mechanisms.

Whereas soft probes can shed light on effects like flow, hard probes are sensitive to the parton energy loss and can serve as an important constraint for the nuclear parton density functions providing information about the nuclear environment.

In this talk, p-Pb results from the ALICE group in Münster will be presented including the deuteron and neutral meson production as well as the analysis of charged jets.
