While conventional WIMP searches focus primarily on low-energy nuclear recoils, a broader class of dark matter models can produce significant signals at much higher recoil energies. In a new search using 2.84 tonne-years of LZ exposure, we extend the nuclear-recoil energy window to approximately 270 keV to probe momentum- and velocity-dependent interactions described by non-relativistic effective field theory, as well as inelastic dark matter models. The search observes one event in a region of low expected background, consistent with a 248 +\/- 23 (stat) +\/- 23 (sys) keVnr nuclear recoil. I will describe the motivation, methodology, and results of this extended-energy search, including the investigation of the high-energy event and possible background interpretations. I will also highlight work carried out at the University of Michigan that helped enable the extension to high recoil energies, particularly the calibration and detector-response modeling of electronic and nuclear recoils, together with studies of backgrounds relevant to the expanded search region.", "occurrence_notes":null, "guid":"152004-21912608@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/152004", "building_id":"1000167", "building_name":"West Hall", "campus_maps_id":"163", "room":"340", "location_name":"West Hall", "has_livestream":0, "cost":"", "tags":["Science","Physics"], "website":"", "sponsors":[ { "group_name":"HEP - Astro Seminars", "group_id":"3799", "website":"" }, { "group_name":"Department of Physics", "group_id":"1965", "website":"" } ], "image_url":"", "styled_images":{ "event_thumb":"", "event_large":"", "event_large_2x":"", "event_large_lightbox":"", "group_thumb":"", "group_thumb_square":"", "group_large":"", "group_large_lightbox":"", "event_large_crop":"", "event_list":"", "event_list_2x":"", "event_grid":"", "event_grid_2x":"", "event_feature_large":"", "event_feature_thumb":"" }, "occurrence_count":1, "first_occurrence":21912608 } , "150199-21908386": { "datetime_modified":"20260818T120700", "datetime_start":"20260916T151000", "datetime_end":"20260916T161000", "has_end_time":1, "date_start":"2026-09-16", "date_end":"2026-09-16", "time_start":"15:10:00", "time_end":"16:10:00", "time_zone":"America\/Detroit", "event_title":"MIPSE Seminar | Xcimer\u2019s Approach to Inertial Fusion Energy", "occurrence_title":"", "combined_title":"MIPSE Seminar | Xcimer\u2019s Approach to Inertial Fusion Energy: Dr. Alison Christopherson, Xcimer Energy Corporation", "event_subtitle":"Dr. Alison Christopherson, Xcimer Energy Corporation", "event_type":"Lecture \/ Discussion", "event_type_id":"13", "description":"Abstract: \nXcimer Energy Corporation is developing a new generation of large\u2011scale, high\u2011efficiency excimer laser systems designed to enable practical inertial fusion energy. This talk will outline the physics and engineering foundations of high\u2011energy KrF laser architectures and their advantages for coupling energy to direct\u2011drive fusion targets. This presentation will describe Xcimer\u2019s integrated roadmap for de\u2011risking and scaling the technology. These strategies include the Phoenix program to demonstrate and validate gas optics performance; Anvil, Xcimer\u2019s first dedicated target\u2011shooter facility to derisk two beam implosion; and Vulcan, a 4\u2011MJ\u2011class laser system intended to demonstrate fusion breakeven. The seminar will also introduce Athena, a conceptual fusion pilot plant featuring a liquid first wall designed for a 40\u2011year lifetime and compatible with high\u2011repetition\u2011rate operation. Together, these developments form a coherent pathway towards high\u2011gain direct\u2011drive targets and commercially relevant fusion energy systems. The talk will highlight the system\u2011level considerations that motivate excimer technology, the target\u2011design implications of higher available laser energy, and the engineering concessions required for a viable fusion power plant.\n\nAbout the Speaker: \nAlison Christopherson is the Head of Target Design at Xcimer Energy Corp. where she leads the development of high\u2011gain direct\u2011drive targets for next\u2011generation excimer\u2011laser\u2013driven inertial fusion energy systems. She earned her B.S. in Nuclear Engineering from the University of Michigan and her Ph.D. from the University of Rochester, specializing in direct\u2011drive inertial confinement fusion. Her doctoral work advanced understanding of alpha particle heating and ignition, earning her the Rosenbluth Award for excellence in plasma physics. She went on to serve as a staff scientist in the Inertial Confinement Fusion program at Lawrence Livermore National Laboratory during the period when ignition was first achieved. Her experience at LLNL reinforced a key conclusion: solid\u2011state laser architectures face fundamental scaling limits for the energy levels required to produce robust, high\u2011gain targets and to accommodate the engineering concessions of a fusion power plant. Motivated by the promise of gas\u2011optics\u2013based excimer technology, she joined Xcimer to lead its target design program and shape the physics basis for the company\u2019s fusion roadmap.\n\nThe seminar will be conducted in person, with livestream on Zoom.

The precision of managers' private information is determined endogenously in market equilibrium, with private and public information acting as substitutes. As portfolio management costs increase, both the performance-based and benchmark components of the optimal contract become more sensitive to investment outcomes, while fewer private signals are incorporated into prices, reducing market informational efficiency. We further show that when a social planner places sufficient weight on the welfare of direct investors and liquidity providers, the socially optimal equilibrium achieves greater price informational efficiency than the decentralized equilibrium.
