TRANSVERSITY 2011 - Third International Workshop on Transverse Polarization Phenomena in Hard Scattering

29 Aug 2011, 08:00 → 2 Sept 2011, 20:35 Europe/Zagreb

Veli Lošinj (Croatia)

Transversity and transverse spin effects are of growing theoretical and experimental interest. Modern developments in hadron physics emphasize the role of correlations between spin and transverse parton momentum, which are crucial to our understanding of the orbital and spin structure of the nucleon in terms of the quark and gluon degrees of freedom in QCD and beyond the collinear approximation. The main aim of the workshop is to provide a playground in which present knowledge in the field of transversity and transverse-momentum dependent distribution and fragmentation functions will be illustrated while allowing new theoretical ideas and experimental perspectives to be aired and discussed vigorously.
