J/ψ measurements in 7 TeV p-p collisions with ALICE using EMCal-triggered events

J/ψ measurements can be performed with the ALICE experiment through the dilepton decay into e−e+ (for rapidity |y|<0.9) and μ−μ+ (for rapidity −4.0Quark Gluon Plasma (QGP). Moreover, these measurements are interesting per se because the mechanism of charmonium production in hadron interactions is not yet fully understood. The ALICE Eletromagnetic Calorimeter (EMCal) pT extends the range of J/ψ measurements, since it provides electron/hadron discrimination for higher pT values in comparison to other electron PID techniques in ALICE. The EMCal can also provide fast triggers for events containing high energy electrons. In 2011, during proton-proton collisions at 7 TeV, the ALICE EMCal trigger was intensively used for event selection of showers above ...
