I will present our recent study of the strong and radiative decays of spin-3 mesons {ρ3(1690), K3(1780), φ3(1850), ω3(1670)} in the framework of an effective quantum field theory approach, based on the SU(3)v-flavor-symmetry. After introducing possible tree level interaction terms, I will compare the fitted effective model results with the experimental data of Particle Data Group. Finally, I...

51. Overview of recent HERMES results on transverse-momentum dependent spin asymmetries

The HERMES experiment has collected a wealth of data using the 27.6 GeV polarized HERA lepton beam and various polarized and unpolarized gaseous targets. This allows for a series of unique measurements of observables sensitive to the multidimensional (spin) structure of the nucleon, in particular semi-inclusive deep-inelastic scattering (SIDIS) measurements, for which the HERMES dual-radiator...
