The following is the request by the DoE HEP office:
In response, the following save-the-date message was sent to the DPF mailing list on January 11, 2017:
"To respond to the 2014 P5 report recommendations in the search for dark matter particles and maintaining a diversity of project scales in our program, DOE Office of High Energy Physics (HEP) is interested in identifying new, small projects for dark matter searches in areas of parameter space (i.e. mass ranges or types of particles) not currently being (or on track to be) explored. HEP is asking for community input in the spring 2017 timeframe in order to plan the program forward. Input is requested on the possibilities for small (the whole project is ~ $10 million or less) dark matter projects in unexplored parameter space. A community workshop, followed by a White Paper would be a good path to provide the input needed. We encourage you to collect information from the community, including theorists and experimentalists involved in non-accelerator and accelerator-based efforts."
"The DOE HEP office has requested that a community-organized workshop be held in early 2017 to examine the next experimental step(s) in the search for dark matter. The focus will be on opportunities for dark matter searches in line with the P5-recommended portfolio of small-scale projects, targeting well-motivated areas of parameter space that are not expected to be covered by existing projects. The workshop will be the first step toward a white-paper report that lays out the science case and possible project concepts. The organization of the workshop is in progress and a bulletin will appear shortly that provides the program, as well as registration and other useful information. This workshop represents an important opportunity to consider new small-scale experimental thrusts for the U.S. Dark Matter program and we encourage all those interested in Dark Matter experiments to attend. Please block off these dates!"
The working groups are listed on the "Scientific Programme" page, along with the names and contact information of the conveners. If you are interested in contributing to a working group, please contact the conveners directly.
