4th International Workshop on Transverse Polarisation Phenomena in Hard Processes (Transversity 2014)

9 Jun 2014, 09:00 → 13 Jun 2014, 19:00 Europe/Rome

Hotel Parco Torre Chia

The workshop focuses on transversity and transverse-spin effects in high-energy hadronic collisions. Parton intrinsic motion and spin, and their correlations, indeed are crucial to our full understanding of the nucleon structure in terms of the quark and gluon degrees of freedom in QCD, beyond the collinear approximation.
