Analysis of ϕ resonance in pp collisions at 900 GeV with the ALICE detector

ALICE is the LHC experiment mainly dedicated to the study of hot and high energy density nuclear matter created in heavy-ion collisions. ALICE has also developed a detailed proton-proton physics programme, in order to exploit its capabilities to investigate the novel energy regime made available by LHC, which turns out to be quite interesting in itself besides being important as a baseline for the heavy-ion data. Results will be presented of the φ resonance measurements done with the first data sets taken at LHC between 2009 and 2010, in pp collisions at 900 GeV. φ transverse momentum spectra and global yields will be shown.
