The production of K∗(892)0 and ϕ(1020) in pp collisions at s√=7 TeV was measured by the ALICE experiment at the LHC. The yields and the transverse momentum spectra d2N/dydpT at midrapidity |y|<0.5 in the range 0<pT<6 GeV/c for K∗(892)0 and 0.4<pT<6 GeV/c for ϕ(1020) are reported and compared to model predictions. Using the yield of pions, kaons, and Omega baryons measured previously by ALICE at s√=7 TeV, the ratios K∗/K−, ϕ/K∗, ϕ/K−, ϕ/π−, and (Ω + Ω¯¯¯¯)/ϕ are presented. The values of the K∗/K−, ϕ/K∗ and ϕ/K− ratios are similar to those found at lower centre-of-mass energies. In contrast, the ϕ/π− ratio, which has been observed to increase with energy, seems to saturate above 200 GeV. The (Ω + Ω¯¯¯¯)/ϕ ratio in the pT range 1-5 GeV/c is found to be in good agreement with the prediction of the HIJING/BB v2.0 model with a strong colour field.
