  One of the key signatures of the Quark-Gluon Plasma (QGP) is the modification
of hadron transverse momentum differential cross-sections in heavy-ion
collisions (HIC) as compared to proton-proton (pp) collisions. Suppression of
hadron production at high transverse momenta ($p_{\rm T}$) in HIC has been
explained by the energy loss of the partons produced in the hard scattering
processes which traverse the deconfined quantum chromodynamic (QCD) matter. The
dependence of the observed suppression on the $p_{\rm T}$ of the measured
hadron towards higher $p_{\rm T}$ is an important input for the theoretical
understanding of jet quenching effects in the QGP and the nature of the energy
loss, while suppression towards lower $p_{\rm T}$ gives information about
collective behaviour. The ALICE experiment at the Large Hadron Collider (LHC)
performs a variety of measurements including the spectra of neutral mesons and
kaons at mid-rapidity in a wide $p_{\rm T}$ range in pp, p-Pb and Pb-Pb
collisions. An overview of ALICE results in HIC and pp collisions at
$\sqrt{s_{NN}}=$2.76 TeV of neutral pions, kaons and eta mesons as a function
of transverse momentum ($p_{\rm T}$) and centrality will be presented. Ratios
$\eta$/$\pi^{0}$, $K^{\pm}$/$\pi^{\pm}$ as well as comparisons to model
calculations will also be discussed.
