SUMMARY:Evan Pease (UCB/Yale) "New results from the 332-live-day exposure of the LUX dark matter experiment"
DESCRIPTION:Abstract:\nEarlier this year the Large Underground Xenon (LUX) experiment completed its final dark matter search from 4850 feet below ground in the Sanford Underground Research Facility in Lead\, South Dakota. Between September 2014 and May 2016 the LUX detector amassed 332 live days of exposure in its hunt for dark matter\, primarily in search of Weakly Interacting Massive Particles (WIMPs)\, a favored dark matter candidate. Our analysis of this exposure yields improved and world-leading constraints on the interaction of WIMPs for a wide range of possible masses\, placing a 90%-confidence exclusion limit on spin-independent WIMP-nucleon cross-section greater than 2.2 x 10^-46 cm^2 at 50 GeV/c^2 WIMP mass. This result includes a factor of 4 improvement over the previous LUX sensitivity to WIMP masses 100 GeV/c^2 and above. This presentation will include a discussion of changes in detector performance from the previous LUX search in 2013\, a description of the “salted” data analysis approach\, and a look at the frequent in-situ calibrations of the complex time-varying detector response during 20 months of operation.

SUMMARY:Leslie Rosenberg (Univ. of Washington) "The Axion Dark-Matter Experiment (ADMX)"
DESCRIPTION:ABSTRACT:\nThe axion is a hypothetical elementary particle whose existence would explain the\nbaffling absence of CP violation in the strong interactions. Axions also happen to be a\ncompelling dark-matter candidate. Axions could comprise the\noverwhelming majority of mass in the universe\, yet they would be extraordinarily difficult\nto detect. However\, several experiments\, either under construction or in operation\,\nwould be sensitive to even the more pessimistically coupled dark-matter axions. The\nAxion Dark-Matter Experiment (ADMX) is perhaps the most powerful of these experiments.\nADMX is in the DOE/NSF Generation-2 portfolio of large dark-matter experiments and is\njust transitioning into data-taking. This talk reviews the capabilities and the status of ADMX.

SUMMARY:Simone Pagan Griso (LBNL) "Highlights from ICHEP on the LHC Results"
DESCRIPTION:Abstract:\n\nThe 38th International Conference on High Energy Physics has\njust concluded in Chicago\, US. New results from various areas of\nhigh-energy particle physics\, as well as neutrino physics\, cosmology\nand theory were presented in front of about 1400 attendees. In\nparticular\, new results from the LHC experiments were highly\nanticipated\, using more than 10/fb of proton-proton collision data\ncollected at a center-of-mass energy of 13 TeV. I will review a\nselection of the results presented\, focusing on the LHC experiments.

SUMMARY:Neil Spooner (Univ. of Sheffield) " Galactic Signatures and Directional Detection of Particle Dark Matter - the CYGNUS Project and Probing below the Neutrino Floor”
DESCRIPTION:Abstract:\nI’ll briefly review the arguments for and status of particle dark matter searches and then focus on the possibility of looking for a definitive galactic signature.  There have been several hints for WIMP dark matter over the years\, most notably the DAM/LIBRE annual modulation result.  There are new efforts to study this\, for instance DM-ICE.  I’ll describe the efforts and latest results then focus on prospects for a directional signal using gas Time Projection Chamber technology including the new CYGNUS global collaboration aiming to deploy targets at multiple latitudes deep underground.
