Abstract (data abstract)
The production of $\rho^{0}$ mesons is measured with the ALICE detector in pp and Pb-Pb collisions at the centre-of-mass energy per nucleon pair, $\sqrt{s_{\rm NN}}$ = 2.76 TeV. The yields of $\rho^{0}$ for rapidity $|y|<0.5$ are presented as a function of transverse momentum ($p_{\rm T}$). The $p_{\rm T}$-integrated and $p_{\rm T}$-differential particle ratios $\rho^{0}/\pi$ are obtained in pp and Pb--Pb collisions. The nuclear modification factors $R_{\rm AA}$ are computed using a proton-proton reference at $\sqrt{s} = 2.76$ TeV.
