%0 Journal Article %T Single spin asymmetries and vector meson production in DIS %A Mauro Anselmino %A Francesco Murgia %J Physics %D 1998 %I arXiv %X We discuss possible measurements and origins of single spin asymmetries in DIS and of some unusual spin properties of vector mesons produced in lepton- nucleon, photon-nucleon and photon-photon interactions. Such effects have already been observed in other processes. %U http://arxiv.org/abs/hep-ph/9807366v1
