Resonance measurements in pp and Pb--Pb collisions with the ALICE   detector
  The study of resonance production in pp collisions helps understanding hadronization mechanisms and tuning the QCD-inspired particle production models. In Pb--Pb collisions, resonances allow one to probe the temperature and time evolution of the fireball.   Transverse momentum spectra have been analyzed for $\kstar$, $\phir$ and $\xstar$ resonances using data from pp collisions at 7 TeV collected by the ALICE detector. A comparison with Monte Carlo event generators shows different levels of agreement for meson spectra, while $\xstar$ is always underestimated.
