Type: Parallel Session: QCD and hadron structure-B3
Inclusive as well as exclusive emissions in forward and central directions of rapidity are recognized as excellent channels to access the proton structure at small-$x$. In this talk, first I will review the formal description of UGD, then I will describe the state of the art of some recent phenomenological analyses on the diffractive electroproduction of $\rho$ mesons. Finally, I will present som ... More

Type: Parallel Session: QCD and hadron structure-B3
Longitudinal and transverse single- and double-spin asymmetries in SIDIS, measured by HERMES, will be presented. These include the latest results on longitudinal double-spin asymmetries, the single-(beam)spin asymmetry, as well as a review of single- and double-spin asymmetries using a transversely polarized target. All those are extracted in multi-dimensional binnings, often for the first time ev ... More

The transversity PDF $h_1^q$ can be accessed in SIDIS by measuring the polarisation of final-state hadrons produced off transversely polarised nucleons. We present the COMPASS results on the transversity-induced polarisation of $\Lambda$ and $\bar{\Lambda}$ hyperons produced off transversely polarised protons. Within the experimental uncertainties, no significant deviation from zero is observed. ... More
Transverse momentum dependent fragmentation functions (TMD FF's) characterize multi-dimensional hadronization processes and their flavor dependence within jets. The LHCb experiment forward spectrometer offers a unique opportunity to measure with great precision hadronization variables $j_T$, z and r in TMD FF's. This talk will present results for measurements of nonidentified hadrons within light ... More
