[clas_members] "Exclusive Meson Production and Short-Range Hadron Structure", Jan 22-24, 2015, Jefferson Lab, Newport News, VA

[Valery Kubarovsky]

Dear Colleagues,
We are pleased to announce that workshop "Exclusive Meson Production and Short-Range Hadron Structure"
will take place on January 22-24 at Jefferson Laboratory, Newport News, VA.

https://www.jlab.org/conferences/emp/index.html

Exclusive meson production processes at high momentum transfer are an essential tool in mapping the nucleon's generalized parton distributions (GPDs) and exploring other aspects of short-range hadron structure (correlations, angular momentum). They complement the information obtained from deeply-virtual Compton scattering by probing specific spin/flavor components of the GPDs and can measure structures that are difficult to access otherwise (gluons, transversity). Substantial progess has been made in the QCD-based theory and analysis of meson production in the last few years, especially in probing quark transversity with pi0 and eta, and gluonic structure with phi and J/psi. A program of targeted experiments in hard exclusive meson production will be performed at JLab with the 12 GeV Upgrade in Hall A, Hall B (CLAS12) and Hall C. The aims of the workshop are to:

Identify outstanding issues in hadron structure that can be addressed with exclusive meson production at high Q2 and/or high t;
Review the experimental tools (detection, polarization, L/T separation) available at JLab12 and the needs for further development;
Discuss theoretical approaches to exclusive meson production, new ideas, and directions for further theoretical studies;
Identify synergies and complementarity between already approved experiments, also between DVCS and meson production.
 

Topics include:

- Mechanism of high-Q2 meson production in QCD and experimental tests
- Exclusive pi0, eta and quark transversity GPDs
- Exclusive pi+, K+ and meson form factors
- L/T separation at JLab with 11 GeV
- Exclusive rho0, rho+, omega and their interpretation
- Exclusive phi, J/psi and gluonic structure
- Polarization observables for pseudoscalar and vector mesons
- Novel QCD approaches to high-t processes
- Backward meson production and applications
 
Registration is free of charge.
