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

G. D. Alexeev, M. G. Alexeev, C. Alice +186

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 im…
