Diffractive $\rho^{0}$ production at COMPASS experiment
The helicity structure of the diffractive leptoproduction of $\rho$ mesons, $\mu+N\rightarrow\mu+N+\rho$, is studied and preliminary results on several spin density matrix elements and $R=\sigma L/\sigma T$ for incoherent exclusive $\rho^{0}$ production from COMPASS 2002 data are presented. The elem...
