Exclusive image production using COMPASS at CERN Original Research Article

COMPASS has measured the incoherent exclusive electroproduction of ρ0 over a wide Q2 range and at View the MathML source. Spin density matrix elements were extracted from the angular distribution. Preliminary results of the analysis of the data taken in 2002 presented here are consistent with a substantial increase of R=σL/σT with Q2 and a weak violation of SCHC, in agreement with other high energy experiments.
