Institute for Nuclear and Particle Astrophysics (INPA) at LBNL
The INPA Seminar weekly talks are on Fridays, starting at 12:00 pm, unless informed otherwise. The seminar talk starts with a brief presentation of the weekly scientific news. Typically, the talks conclude by 1:00 pm. The seminars are held in the Sessler Conference Room, located in Bldg. 50A- 5132.

INPA Seminar Speaker: Alex Droster (UC Berkeley)-Title: Searching high and low for dark matter axions
January 31 @ 12:00 pm - 1:00 pm
Date: January 31, 2025
Time: 12:00 am – 1:00 pm
Location: Sessler Conference Room – 50A-5132 [Hybrid and In-Person]
Speaker: Alex Droster (UC Berkeley)
Title: Searching high and low for dark matter axions
Abstract: After almost 50 years, the axion remains the only mainstream solution to the non-observation of CP violation in the strong force. It is also a very attractive solution to the dark matter problem of the universe due to its long lifetime, weak Standard Model couplings, and production mechanisms in the early universe that generate cosmologically relevant density. However, nearly half a century after its proposal, the axion remains undiscovered. In this talk I will review experimental efforts across nine orders of magnitude in axion mass aimed at directly detecting this elusive particle, focusing on the HAYSTAC and ALPHA experiments looking for high mass post-inflationary axions, and DMRadio on the opposite end of the scale searching for very low mass GUT-scale axions. I will also describe the quantum enhancement techniques which have already enabled us to operate below the Standard Quantum Limit, and strategies for extending these ultrasensitive searches to both higher and lower frequencies.
