[Cuga] 3D Nucleon Tomography Workshop- a message from David Richards

[Lorelei Chopard]

Dear Colleague,

we are happy to announce workshop at Jefferson Lab on 3D Nucleon 
Tomography Workshop (/Modeling and Extraction Methodology). /Those 
interested in participation are encouraged to contact members of the 
organizing committee at 3DWorkshop at jlab.org.

Venue: Jefferson Lab, Newport News, Virginia

Date: March 15-17

*Goals of the workshop*

The discovery of Generalized Parton Distributions (GPDs) and more 
recently Transverse-Momentum-Dpendent Distributions (TMDs) has opened 
the window on a three-dimensional imaging of the nucleon, going far 
beyond the one dimensional, longitudinal  structure probed in 
Deep-Inelastic Scattering, and the transverse structure encoded in the 
different form factors.  The three-dimensional imaging of the valence 
quarks is a cornerstone of the current worldwide experimental programs, 
and a future proposed EIC will extend this imaging to sea quarks and 
gluons.  This experimental effort is complemented by theoretical 
advances through lattice QCD calculations and through QCD-inspired 
pictures of the nucleon.  However, fully capitalizing on these 
experimental and theoretical efforts demands a structured connection 
between theory, experiment and phenomenology, and one capable of 
handling the increasing data and computational challenges that such a 
connection will entail.

The aim of the workshop is to detail the requirements for an analysis 
framework, to examine the theoretical and experimental components that 
need to be incorporated, and to study approaches to the computational 
challenges that these requirements will entail. The outcome of the 
workshop will be a white paper, and the establishment of collaborative 
effort aimed at tackling these challenges, and ensuring that the 
resultant framework can be applied across the emerging nuclear 
experimental and theoretical programs, including at a future EIC. The 
workshop  will address three specific topics. Firstly, the analysis 
methodology and the data/analysis requirements at current and upcoming 
experiments, including BNL, CERN, GSI, JLab and a future EIC. Secondly, 
the theoretical and phenomenological requirements, and how those 
requirements can be integrated within an analysis framework. Finally, 
the requirements for future experimental extraction and validation, in 
particular through the incorporation of Monte Carlo simulation components.

The workshop will begin on the Wednesday morning, and finish at 
lunchtime on the Friday. The first two days will comprise plenary talks 
outlining the issues described above, followed by collaborative effort 
in  working groups. Outcome of these will be presented Friday morning.

Participation in the workshop will be by invitation to members of the 
computational, experimental and theoretical communities, but those 
interested in participation are encouraged to contact members of the 
organizing committee at 3DWorkshop at jlab.org. Further details are at 
https://www.jlab.org/conferences/3Dmodeling, which will be updated as 
the organization progresses.
