Single spin asymmetries in polarized proton-proton, polarized antiproton-proton inclusive processes
M. Anselmino, M. Boglione, F. Murgia
Single spin asymmetries in polarized proton(antiproton) + proton -> pion + X have been measured to be large. They can be understood within perturbative QCD by introducing new k_per…

Quark fragmentation and off-diagonal helicity density matrix elements for vector meson production
M. Anselmino, M. Bertini, F. Murgia +1
As confirmed by some recent LEP data on phi, K^* and D^*0 production, final state interactions in quark fragmentation may give origin to non-zero values of the off-diagonal element…

Single spin asymmetries and vector meson production in DIS
Mauro Anselmino, Francesco Murgia
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…
