Status and perspectives of J/ψ analysis in proton-proton collisions with ALICE at the LHC — •Steffen Weber for the ALICE collaboration — Research Division and ExtreMe Matter Institute, GSI Helmholtzzentrum für Schwerionenforschung, Planckstr. 1, 64291 Darmstadt — Institut für Kernphysik, Technische Universität Darmstadt, Schlossgrabenstr. 9, 64289 Darmstadt

ALICE is an experiment at the Large Hadron Collider especially designed to study the hot and dense matter created in heavy ion collisions. Charmonium mesons, bound states of charm-anticharm quarks, are prominent probes of the hot deconfined created matter.

Measurements in proton-proton collisions provide a necessary baseline for the interpretation of the data in lead-lead and in proton-lead collisions and are as well an important testing ground for perturbative and non-perturbative QCD theory.

The current status of J/ψ analysis in the dielectron decay channel in proton-proton collisions in ALICE will be presented and future opportunities for measurements in the Run2 of LHC data taking will be discussed.
