Measurement of the spin-density matrix elements in exclusive electroproduction of ρ0 mesons at HERA

Measurement of the spin-density matrix elements in exclusive electroproduction of ρ0 mesons at HERA

Exclusive electroproduction of ρ0 mesons has been measured using the ZEUS detector at HERA in two Q2 ranges, 0.25 < Q2 < 0.85 GeV2 and 3 < Q2 < 30 GeV2. The low-Q2 data span the range 20 < W < 90 GeV; the high-Q2 data cover the 40 < W < 120 GeV...
