Charmonium Production in pp Collisions with ALICE.

Ionut-Cristian Arsene
The ALICE Collaboration studies the production of $J/\psi$ meson in pp collisions at the center-of-mass energies of 2.76 and \unit{7}{\TeV} at mid- and forward-rapidity. Inclusive production cross-sections are presented as a function of the collision energy, rapidity and transverse-momentum. The $J/\psi$ polarization measurements in the helicity and Collins-Soper frames is discussed. A novel result on the correlation between the collision charged particle multiplicity and $J/\psi$ yield is also shown.
