Spin Density Matrix Elements in Exclusive $\rho ^0$ Meson Muoproduction

Spin Density Matrix Elements in Exclusive $\rho ^0$ Meson Muoproduction

We report on a measurement of Spin Density Matrix Elements (SDMEs) in hard exclusive $\rho ^0$ meson muoproduction at COMPASS using 160~GeV/$c$ polarised $ \mu ^{+}$ and $ \mu ^{-}$ beams impinging on a liquid hydrogen target. The measurement covers the kinematic range 5.0~GeV/$c^2$ $< W
