Workshop on "New Ideas in Dark Matter Searches"

Fourth annual workshop of the Group on Precision Measurements and Fundamental Constants

Friday, April 12, Sheraton Denver Downtown Hotel, Plaza E

"New Ideas in Dark Matter Searches" is a one-day workshop organized by the APS Topical Group on Precision Measurements and Fundamental Constants (GPMFC). It will take place in Denver, CO on April 12, 2019—the day before the APS April meeting begins. It will be held at the Sheraton Denver Downtown Hotel, the site of April Meeting 2019. The goal of the workshop is to survey a broad range of new ideas in dark matter searches and bring together researchers from different communities. The audience will consist of senior researchers, postdocs, and students who are using a wide variety of tools for the dark matter searches.

Links to previous GPMFC workshops can be found on the GPMFC website.
