  2. Spin Puzzle • : quark-spin contribution • global analysis of DIS and SIDIS data • flavor decomposition • extension to low-Q2 • transversity • G: gluon-spin contribution • L: orbital angular momentum (OAM) • DVCS • transverse spin asymmetries • Sivers function and Collins function DIS2006 Spin WG Summary
