Observation of the strange sea in the proton via inclusive phi meson production in neutral current deep inelastic scattering at HERA

Inclusive phi-meson production in neutral current deep inelastic e+p scattering has been measured with the ZEUS detector at HERA using an integrated luminosity of 45 pb^{-1}. The phi mesons were studied in the range 10
