Abstract

Inclusive φ(1020)-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 φ mesons were studied in the range 10 < Q² < 100 GeV², where Q² is the virtuality of the exchanged photon, and in restricted kinematic regions in the transverse momentum, p_T, pseudorapidity, η, and the scaled momentum in the Breit frame, x_p. Monte Carlo models with the strangeness-suppression factor as determined by analyses of e⁺e^- annihilation events overestimate the cross sections. A smaller value of the strangeness-suppression factor reduces the predicted cross sections, but fails to reproduce the shapes of the measured differential cross sections. High-momentum φ mesons in the current region of the Breit frame give the first direct evidence for the strange sea in the proton at low x.
