USLUA annual meeting
WRF Data Science Studio
Physics and Astronomy Tower (PAC)
The US LHC Users Association (https://www.uslua.org) represents the US community of scientists and engineers working in the LHC physics and accelerator programs, and provides a forum of support for, and discussion of, US participation at CERN. We aim to support and uplift US personnel — particularly early career scientists and engineers — as well as acting as a communications channel between the community, US agencies, and the Congressional and Executive Branches.
Please note that early career members of our community are especially encouraged to attend in person, and travel support for a limited number of early career participants can be provided. Requests should be addressed to the Local Organizing Committee. We also encourage them to sign up for Lightning Round Talks to win a trip to our annual advocacy meeting to Washington DC in the Spring.
Early Career Scientists: There is still room left in the schedule for remote Lightning Round talks. Although registration for local participation closed on December 7th, remote registration is open until the meeting. No fee required.
Registration Fee:
- Non-Students: $275
- Students: $200 (possibility of aid - see registration)

USLUA is a 501(c)(3) tax-exempt non-profit that needs funding to support its mission.
Typically raise funding through the following avenues:
- Lab drive
- Community drive
- Support for the users meeting (but only if the meeting is at FNAL):
- University Research Association (URA) Visiting Scholars Program
Travel support for annual meeting @ FNAL
- University Research Association (URA) Visiting Scholars Program
Our expenses:
-
sending early career members to the DC trip
-
materials to give staffers on the DC trip
-
subsidizing early career members to attend our annual meeting
This year (2025), reached out to the national labs.
Traditionally, most of the national labs with LHC programs have supported us each year. We are optimistic about this support continuing in FY25-26, but the timeline compared to previous years has been delayed due to the government shutdown
Community drive in progress -- led by David
Received support during this meeting! Thank you!

Melting LHC detectors: a novel search for stopped long-lived particles
Particles at the TeV scale with lifetimes of a year or longer could have been abundantly produced at the LHC yet escaped detection because of backgrounds, and could still be trapped within detector materials. With gluinos in split-supersymmetry as a working example, we show that these trapped particles can be recovered from detector materials once prepared in liquid form, for example, by melting silicon detectors, extracting liquid argon from the electromagnetic calorimeter, or constructing a large water pool near ATLAS or CMS. These liquid samples can then be processed using iterative centrifugation followed by mass spectrometry, enabling single-particle sensitivity in macroscopic samples. This method can potentially discover gluinos up to 3 TeV in mass at the HL-LHC.
