[Cuga] A call for EIC activity participation---a message from Zein-Eddine Meziani

[Rachel Harris]

Dear Colleagues,

A series of workshops have been planned by the Jefferson Lab User 
Community to explore the scientific opportunities that could be provided 
by a future Electron-Ion Collider in areas of physics of current 
interest to the community. These workshops are open to all in the JLab 
User community and to all in the larger community, world-wide, that is 
interested in this physics. A key goal of the four science workshops and 
the detector/interaction region workshop that will follow will be to 
determine physics-based requirements for the characteristics of a 
Collider that would support the identified opportunities in each of 
these areas. The longer-range goal of this effort will be the definition 
of the characteristics of a collider that would optimally address as 
much of this physics as possible. The science workshops will include: 
two on e-p physics; one on e-A physics; and one on Electro-Weak physics.

Further information on the series of workshops can be found on the 
general EIC at JLab web pages, https://eic.jlab.org/wiki/ , or on the 
workshop-dedicated web pages given below. The time-ordered series of 
workshops is as follows:
1) Workshop on Partonic Transverse Momentum Hadrons: Quark Spin-Orbit 
Correlations and Quark-Gluon Interactions. March 12-13, 2010 at Duke 
University. http://michael.tunl.duke.edu/workshop/index.php
Organizing Committee: Haiyan Gao (Chair), Mauro Anselmino, Harut 
Avagyan, Matthias Burkhardt, Jian-Ping Chen, Evaristo Cisbani, Cynthia 
Keppel, Jen-Chieh Peng and Feng Yuan

2) Workshop on Electron-Nucleon Exclusive Reactions: 3D Mapping of the 
Glue and Sea Quarks in the Nucleon. March 14-15, 2010 at Rutgers 
University. http://www.physics.rutgers.edu/np/2010rueic-home.html/
Organizing Committee: Ronald Gilman (Chair), Tanja Horn, Pawel 
Nadel-Turonski, and Christian Weiss Advisory Committee: Stanley J. 
Brodsky, Larry Cardman, Markus Diehl, and Zein-Eddine Meziani

3) Workshop on Nuclear Chromo-Dynamic Studies with a Future Electron-Ion 
Collider. April 7-9, 2010 at Argonne National 
Laboratory.http://www.phy.anl.gov/mep/EIC-NUC2010/
Organizing Committee: Kawtar Hafidi (Co-Chair), Will Brooks (Co-Chair), 
Alberto Accardi, Claudio Ciofi Degli Atti, Dave Gaskell, Vadim Guzey, 
and Paul Hoyer

4) A Workshop on Electroweak Physics with an Electron-Ion Collider, 
chaired by Krishna Kumar and Kent Paschke, will be organized around 
early May, with further information forthcoming.

5) Lastly, a workshop dedicated to the detector and interaction region 
needs, folding in the input from, and following the series of science 
workshops, will be held at Jefferson Lab, chaired by Charles Hyde, with 
dedicated input and representation of the organizing committees of the 
science workshops (Jian-Ping Chen, Pawel Nadel-Turonski, Dave Gaskell, 
and TBD).

It is our intention that this effort will continue, with the goal of 
developing a ?White Paper? summarizing the efforts of the full series of 
workshops. We have asked each of the core groups organizing these 
workshops to also take a lead role in preparing a section of a White 
Paper on the Collider. The style and approach will be similar to that 
used in developing the ?Pre-Conceptual Design Report (pCDR) for the 
Science and Experimental Equipment for The 12 GeV Upgrade of CEBAF ? 
(see http://www.jlab.org/div_dept/physics_division/pCDR_public/pCDR_final/ )
with each of the workshop organizing committees (probably expanded and 
evolving in time) becoming one of the topical sub-groups of the 
editorial board for the White Paper on the Collider. As an intermediate 
step, a presentation of the findings of each working group will be 
presented during the 2010 Annual Jefferson Lab Users Group Meeting to be 
held in June, for input of the wider User Community.

Lastly, we anticipate that this process, and these core groups 
(augmented with other interested JLab users and others from the 
international community who are interested in participating), will 
provide important input to the effort of the larger nuclear physics 
community to define the physics and hardware of a future collider, both 
at future meetings of the Electron Ion Collider Collaboration and, in 
particular, at the upcoming Institute of Nuclear Theory Program on 
Gluons and the Quark Sea at High Energies: Distributions, Polarization, 
Tomography (INT10-03). The INT program, which will take place from 
September 13 to November 19, 2010, will be dedicated to addressing open 
questions about the dynamics of gluons and sea quarks in the nucleons 
and nuclei, to also further motivate scientific arguments and refine key 
parameters for an Electron Ion Collider. Please 
seehttp://www.int.washington.edu/PROGRAMS/10-3/ for more information.

We are looking forward to an exciting series of workshops, and invite 
the Jefferson Lab User community and all others who are interested in 
this science to engage in this important activity. Please contact the 
chairs and/or organizing committees of the various workshops and inform 
them of your interest.
We take this opportunity to profoundly thank the chairs, organizing and 
advisory committees of the series of workshops for their willingness to 
assume these responsibilities, and ask you to join and support them in 
this important effort.

Best regards,


Larry Cardman and Zein-Eddine Meziani (chair of the JLab UGBoD)
