3 Physics Goals Quarkonia: Bound states of heavy quark pairs, created in early stage of collision Primary physics goals: Study elementary production mechanism (p+p) Probe properties of the QGP (A+A) Frederick Kramer Quarkonia Measurements with ALICE 3 / 19

4 Elementary Reactions Quarkonia production: Colour Singlet Model Colour Octet Model Colour Evaporation Model [Phys. Lett. B333 (1994) ] Frederick Kramer Quarkonia Measurements with ALICE 4 / 19
