Description
Preliminary results from exclusive production of ρ0 mesons at the COMPASS experiment at CERN, using a 160 GeV polarized muon beam and a large polarized nuclear target, are presented. The studied reaction is exclusive incoherent ρ0 production, μN → μNρ0, with N being the nucleon in any of the nuclei of the target. The measurements were done in a wide range of Q2: 0.01 < Q2 < 10 GeV2, at (W) ∼ 10 GeV. The results for r0400, r11-1, r041-1 and Imr31-1 ρ0 spin density matrix elements and the ratio R = σL/σT, based on 700 000 events selected from the year 2002 data, are shown and commented. (author)
