SUMMARY:Speaker: Michael Williams (University of Michigan) - Title: Searches for Particle Dark Matter with LZ and TESSERACT
DESCRIPTION:Research Progress Meeting \nDate: December 5\, 2023 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Michael Williams (University of Michigan) \nTitle: Searches for Particle Dark Matter with LZ and TESSERACT\n \nAbstract: The search for particle dark matter is one of the primary challenges in modern physics. Direct detection experiments typically rely on measuring signals produced when dark matter particles recoil off a detector target. In this talk\, I will first discuss the LUX-ZEPLIN (LZ) experiment\, which uses a dual-phase xenon time projection chamber to look for WIMP dark matter that recoils off the xenon nucleus. I will discuss LZ detector construction\, first WIMP search results\, and limits on effective field theory (EFT) searches of dark matter. I will then discuss the search for low-mass dark matter with TESSERACT; this encompasses interactions with two types of novel\, ultra-sensitive detectors – SPICE and HeRALD. Both SPICE and HeRALD use transition edge sensors (TESs) for cryogenic readout\, while using different targets: polar crystals and superfluid helium-4\, respectively. I will describe the development and first measurements of new Iridium-Platinum (IrPt) TESs and the commissioning of the new HeRALD detector at LBNL. \n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95679892182?pwd=RU5xU2dDRFNabnR1U3pQMklkYWFIdz09 \nMeeting ID: 956 7989 2182 \nPasscode: 169037
