Electroproduction of phi mesons
Journal Article
·
· Phys. Rev. Lett.; (United States)
We report measurements of the electroproduction of phi mesons from hydrogen at Q/sup 2/ values of 0.23, 0.43, and 0.97 GeV/sup 2/ with t varying from 0.125 to 1.3 GeV/sup 2/ at each Q/sup 2/ point. The data show no evidence for a Q/sup 2/ dependence of the slope of the t distribution; the forward cross section falls with increasing Q/sup 2/ as the square of the phi propagator; the decay angular distributions agree with the predictions of s-channel helicity conservation; and the ratio of the longitudinal to the transverse component increases linearly with Q/sup 2/.
