Improving η-Meson Reconstruction in the ALICE Experiment
A statistical method for extracting the η → γγ signal upon rejecting those γ clusters that form pairs with invariant masses close to that of the π$^{0}$ meson is proposed. The η selection efficiency (the ratio between the numbers of selected and produced η mesons) and the signal-to-background ratio...
