Exclusive $\rho^{0}$ Production in Polarized DIS at SMC / Tripet, Angele (Bielefeld U.)
Preliminary spin cross section asymmetries for exclusive $\rho^{0}$ lepto-production, $\vec{\mu} + \vec{N} \to \mu' + N + \rho^{0} (\rho^{0} \to \pi^{+} \pi^{-})$, are reported. These asymmetries have been determined for the first time by the Spin Muon Collaboration (SMC) at low Q^2 (photoproduction) and at large Q^2 (DIS) for different $p_T^2$ intervals in the kinematic range $0.01 <Q^2< 60 GeV^2$ and $140 < W^2 < 310 GeV^2$ (<W> \simeq 15 GeV) for the full SMC data set.

Double-spin asymmetry in exclusive $\rho^{0}$ meson production / Grajek, O A (Warsaw, Inst. Nucl. Studies)
The longitudinal double-spin asymmetry $A^{\rho}_{1}$ extracted from exclusive muoproduction of $\rho^{0}$ mesons, $\mu+N\rightarrow\mu+N'+\rho^{0}$, is studied using 2002 and 2003 data from the COMPASS experiment. [...]

Diffractive $\rho^{0}$ production at COMPASS experiment / Sandacz, A (Warsaw, Inst. Nucl. Studies) /on behalf of the COMPASS Collaboration
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 elements $r^{04}_{00}$, $r^{04}_{1-1}$, $\Im mr^{3}_{1-1}$, $r^{1}_{1-1}$ and $R$ are measured at $\langle W\rangle =$ 10 GeV in a wide range of $Q^{2}$, 0.01 $< Q^{2} <$ 10 GeV$^{2}$. [...]

Spin effects in exclusive $\rho^{0}$ meson production at COMPASS experiment / Grajek, O A (Warsaw, Inst. Nucl. Studies) /on behalf of the COMPASS Collaboration
Preliminary results from exclusive production of $\rho^{0}$ 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 $incoherent \rho^{0}$ production, $\mu N\rightarrow\mu N\rho^{0}$, with $N$ being the nucleon in any of the nuclei of the target. [...]
