Type: contributed talk Session: GPDs andTMDs
Exclusive meson electroproduction at different squared four-momenta of the exchanged virtual photon, Q^2, and at different four-momentum transfers, t and u, can be used to probe QCD's transition from hadronic degrees of freedom at long distance scale to quark-gluon degrees of freedom at short distance scale. Backward-angle meson electroproduction was previously ignored, but is anticipated to ... More

Type: invited talk Session: GPDs andTMDs
Investigation of GPDs and TMDs represents one of the major goals of the COMPASS-II program. Together, GPDs and TMDs provide the most complete description of the partonic structure of the nucleon. GPDs are experimentally accessible via lepton-induced exclusive reactions, in particular DVCS and DVMP. At COMPASS, these processes are investigated using the 160 GeV polarized muon beams. The DVCS cross ... More

Type: invited talk Session: GPDs andTMDs
In this talk it is discussed how gluon TMDs - in particular the distribution of linearly polarized gluons - can be accessed in proton collisions at the LHC. A particularly promising reaction is the production of quarkonium pairs. Using existing LHCb data for this final state allows to obtain a first idea of how the TMD distribution of unpolarized gluons in the nucleon might look like. In addition ... More

Type: contributed talk Session: GPDs andTMDs
The Mellin moments of Generalized Parton Distributions connect to quantities that describe the QCD energy momentum tensor. They allow us to single out the separate contributions from quarks and gluons. Partonic orbital angular momentum (OAM) plays a key role in our understanding of the long standing proton spin puzzle. Our recent work demonstrates the connection between quark gluon interactions an ... More
