Abstract
The exclusive production of rho(0) mesons in deep inelastic electron-p roton scattering has been studied using the ZEUS detector Cross sectio ns have been measured in the range 7 < Q(2) < 25 GeV2 for gammap cent re of mass (c.m.) energies from 40 to 130 GeV. The gammap --> rho(0)p cross section exhibits a Q(-(4.2+/-0.8-0.5+14)) dependence and bath l ongitudinally and transversely polarised rho(0)'s are observed. The ga mmap --> rho(0)p cross section rises strongly with increasing c.m. en ergy, when compared with NMC data at lower energy, which cannot be exp lained by production through soft pomeron exchange. The data are compa red with perturbative QCD calculations where the rise in the cross sec tion reflects the increase in the gluon density at low x.
