TMDs and DPDs (A16*)

• Subject Area: Nuclear and Elementary Particle Physics, Quantum Mechanics, Relativity, Fields
• Term: from 2016 to 2020
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 35592816

QCD experiments and theory concentrated until about a decade ago primarily on collinear reactions. The non-perturbative input needed for the theoretical description of such reactions are primarily the parton distribution functions (PDFs), Generalized Parton Distribution Functions (GPDs) and Distribution Amplitudes (DAs), see project A03 and A14. Recent and planned facilities will explore in great detail also the transverse structure of hadrons as well as the transverse momentum dependence of reactions. On the theory side non-collinear physics implies the need to treat gauge links consistently. We plan to perform lattice determinations of some quantities characterizing Transverse Momentum Dependent PDFs (TMDs) and Double Distributions (DDs).
