Description
Generalized parton distributions (GPDs) provide a dynamical picture of the nucleon. The exclusive production of $\rho^0$ mesons off a transversely polarised target is sensitive to the nucleon helicity-flip GPDs $E$ which are related to the total angular momentum of quarks and gluons.\\
In 2007 and 2010 the COMPASS experiment at CERN collected data by scattering a 160 GeV/c muon beam on a transversely polarised NH$_3$ target. The final state particles were detected with the two-stage spectrometer with high resolution tracking and calorimetry. In this talk new results for the azimuthal asymmetries $A_{\text{UT}}$ and $A_{\text{LT}}$ are presented.
