Transverse Target-Spin Asymmetry of Exclusive ${\rho }^0$ Meson Production on Proton at HERMES

Armine Rostomyan, Jeroen Dreschler

Preliminary measurements are reported on the azimuthal single-spin asymmetry of exclusive rho0 mesons for a transversely polarized hydrogen target at HERMES using the 27.6 GeV HERA…
