Abstract

We studied the exclusive reaction ep --> e' p' phi using the phi -->K+ K- decay mode. The data were collected using a 4.2 GeV incident electron beam and the CEBAF Large Acceptance Spectrometer (CLAS) at the Thomas Jefferson National Accelerator Facility. Our experiment covers the range in Q(2) from0.7 to 2.2 GeV2 and W from 2.0 to 2.6 GeV. Taken together with all previous data, we find a consistent picture of phi production on the proton. Our measurement shows the expected decrease of the t slope with the vector-mesonformation time c Delta tau below 2 fm. At <c Delta tau > = 0.6 fm, we measure b(phi) = 2.27 +/- 0.42 GeV-2. The cross section dependence on W as W0.2+/- 0.1 at Q(2), 1.3 GeV2 was determined by comparison with phi productionat HERA after correcting for threshold effects. This is the same dependence as observed in photoproduction.
