Abstract

Electroproduction of exclusive ϕ vector mesons has been studied with the CLAS detector in the kinematic range 1.4≤ Q<sup>2</sup>≤ 3.8 GeV<sup>2</sup>,0.0≤ t′≤ 3.6 GeV<sup>2</sup>, and 2.0≤ W≤ 3.0 GeV. The scaling exponent for the total cross section as 1/(Q2+M2ϕ)n was determined to be n=2.49±0.33. The slope of the four-momentum transfer t′distribution is bϕ=0.98±0.17 GeV<sup>−2</sup>. Under the assumption of s-channel helicity conservation, we determine the ratio of longitudinal to transverse cross sections to be R=0.86±0.24. A two-gluon exchange model is able to reproduce the main features of the data.
