Abstract

The elastic electroproduction of phi mesons is studied at HERA with the H1detector for photon virtualities 1 < Q(2) < 15 GeV2 and hadronic centre ofmass energies 40 < W < 130 GeV. The Q(2) and t dependences of the cross section are extracted (t being the square of the four-momentum transfer to the target proton). When plotted as function of (Q(2) + M-v(2)) and scaled bythe appropriate SU(5) quark charge factor, the phi meson cross section agrees within errors with the cross sections of the vector mesons V = rho, omega and J/psi. A detailed analysis is performed of the phi meson polarisation state and the ratio of the production cross sections for longitudinally and transversely polarised phi mesons is determined. A small but significantviolation of s-channel helicity conservation (SCKC) is observed. (C) 2000 Elsevier Science B.V. All rights reserved.
