About the INPA Seminars

All seminars are on Fridays (unless otherwise noted) and start at 12:00 (noon) with a brief presentation of the weekly scientific news. Typically the talks end by 13:00. The seminars take place in Bldg. 50A, room 5132.

The committee members are:

The following Seminar schedule for the Institute for Nuclear and Particle Astrophysics is tentative. The seminar becomes final usually a few days before the Friday of the talk.

Aaron Manalaysay (UC Davis) – 178 nm: The magic of liquid xenon and the search for dark matter

March 22, 2019 @ 12:00 pm - 1:00 pm

The introduction of liquid-xenon (LXe) to the field of dark-matter direct detection caused a paradigm shift in this search. Primarily focused on the search for the Weakly Interacting Massive Particle, LXe detectors have improved our sensitivity to these dark-matter candidates by a factor of 10,000 since their introduction roughly ten years ago, compared to the factor of 50 sensitivity improvement that the field had covered in the twenty years before that. The rapid pace at which LXe detectors have pushed the field is due in part to their ability to scale to arbitrarily large size, thereby drastically reducing the rates of background signals in these rare-event searches. Though these detectors have seen tremendous successes, each result has been accompanied by its own set of challenges to be overcome, which will also be true for the next generation experiments. I will describe the most recent such U.S.-based experiment, LUX, and highlight the key innovative analyses that led to its impressive results. I will extend the discussion to cover LUX’s upcoming LBL-led successor, LZ, which will be sensitive to WIMP-nucleus interactions as rare as roughly 0.5 events/kg/millennium. Time permitting, I will expand the view by discussing the ways in which LXe is a powerful tool for probing non-WIMP dark-matter candidates.

Sessler Conference Room CA

INPA guests from campus can now come up to the lab early on Fridays. The INPA Common Room (50-5026) is reserved for our guests from 10:00 am to 12:00 noon, and from 1 pm to 5 pm. Note that the seminars are now held in 50A-5132 to accommodate a larger number of attendees.

Also, on Fridays from 1:00 pm to 2:00 pm you are welcome to join the INPA Speaker for a brown-bag lunch in the small Pers Hall conference room, 54-130B.

INPA Tea Series

The Physics and Nuclear Science Divisions have together been leaders in revolutionary changes in our understanding of neutrinos and cosmology. Everyone is welcome to attend the open forum. Tea and light refreshments will be served.
