Dark Forces: Searches for New Forces at the GeV-scale

chaired by Rouven Essig (SLAC), Philip Schuster (SLAC), Natalia Toro (Stanford University), Michael Peskin (SLAC), Mathew Graham (SLAC), Aaron Roodman (SLAC), Jay Wacker (SLAC)
from to (US/Pacific)
at SLAC National Accelerator Laboratory ( Bldg. 48 ROB A/B/C/D )
Description 
Theoretical models related to dark matter have proposed that there are long-range forces mediated by new gauge bosons with masses in the MeV to GeV range and very weak coupling to ordinary matter. The experimental constraints on the existence of these new gauge bosons are quite weak. This workshop will bring together theorists and experimentalists to stimulate progress in searching for these "dark forces" in three arenas:
   1. new fixed-target experiments at electron and proton accelerators such as JLab, SLAC, and Fermilab;
   2. searches at high-luminosity e+e- experiments, including BaBar, BELLE, CLEO-c, KLOE, and BES-III;
   3. searches at the Tevatron experiments.
