Ratios of transverse-momentum spectra of $\ks$ and $\ph $ in inelastic events at $\sqrt{s}$ = 7 and 8 TeV to the transverse-momentum spectra in pp collisions at $\sqrt{s}$ = 2.76 TeV. The statistical and systematic uncertainties are shown as vertical error bars and boxes, respectively. The normalization uncertainties are indicated by boxes around unity.
