First Measurement of[phi] meson production in Au+Au collisions has been conducted by E917 at BNL-AGS via selecting events with identified K[sup+]K[sup[minus]] pairs. Preliminary results on the invariant mass spectra of K[sup+]K[sup[minus]] pairs and the m[sub T] spectra are presented. Also, the inverse slope T, dN/dy, the ratio of[phi]/K[sup[minus]], ratio of[phi]/K[sup+]K[sup[minus]] and their centrality dependences are extracted in a rapidity range of y= 0.9-1.4. Indications on the possible mechanisms of[phi] production are discussed.

The production of [phi] mesons from, central Si + Au collisions has been measured by E859 at the BNL-AGS by selecting events with identified KK− pairs. The values for the mass and width of the [phi] obtained from the invariant mass of the kaon pairs are consistent with those of the Particle Data Book. Preliminary results for the invariant 1/2[pi]m{sub T} d2n/dm{sub T}dy distribution and dN/dy are presented.

The first measurements of [phi] meson production in Au-Au collisions at AGS energies are presented via the decay to K K−. A measurement of the centrality dependence of the yield shows an increase similar to that seen for the K− with a spectral shape consistent with a relativistic Breit-Wigner distribution within the statistical errors of the present data set. Future analysis using the full data set with 4 times the statistics will allow a more accurate determination of the yields, slopes and spectral shapes.
