Ratios of helicity amplitudes for hard exclusive $\rho^0$ electroproduction on transversely polarized protons
The HERMES experiment collected a wealth of deep-inelastic scattering data using the 27.6 GeV polarized lepton beam at HERA and various pure gas targets, both unpolarized and polarized. This allowed for a series of diverse measurements. [...]

Ratios of helicity amplitudes for exclusive $\rho^0$ electroproduction on transversely polarized proton
Exclusive $\rho^0$-meson electroproduction is studied by the HERMES experiment, using the 27.6 GeV longitudinally polarized electron/positron beam of HERA and a transversely polarized hydrogen target, in the kinematic region 1.0 GeV$^2$ < Q$^2$ < 7.0 GeV$^2$, 3.0 GeV < W < 6.3 GeV, and −t′ < 0.4 GeV$^2$. Using an unbinned maximum-likelihoodmethod, 25 parameters are extracted. [...]
