Speakers: Rebecca Leane (SLAC and KIPAC) Sub-GeV dark matter is a well-motivated possibility. However, its feeble interactions make it hard to detect, often falling below experimental thresholds, requiring new detection ideas. In this talk I will describe two complementary, data-driven strategies to close in on light dark matter. First, I will show how large neutrino ... Read more
Speakers: Joel Walker (Sam Houston State University) I’ll be describing an intervention targeting math readiness for incoming physics and pre-engineering students, which has been co-developed with faculty colleague James Dent at Sam Houston State. Our “Physics Bootcamp” course teaches the mathematical methods required for first-year physics and engineering, from the perspective favored by physicists. Motivated ... Read more
Speakers: Michael Stadbauer (Max Planck Institute for Physics/Technical University of Munich (TUM)) As an elegant solution to the strong CP problem and promising dark matter candidate, the QCD axion is one of the best motivated particles beyond the SM. On the phenomenological side, it is extremely predictive as all its couplings to SM particles, as ... Read more

Speakers: Louis E. Strigari (Texas A&M University) New three-dimensional measurements of the positions and velocities of stars, in particular from the Gaia observatory, have provided unprecedented information on the dynamics of the Milky Way and Local Group of galaxies. In this talk I will focus on the implications of these measurements for the formation and ... Read more
Speakers: Prof. Dejan Stojkovic (SUNY, Buffalo) We formulated an alternative to quantum mechanics, whose basic starting point is pure information represented by binary sequences, without any reference to space, time, and matter. Defining correlations between the sequences, we derived highly non-trivial QM results: rules of angular momentum addition, quantum harmonic oscillator, Clebsch-Gordan coefficients, and Wigner’s d-matrix formula. ...

Speakers: Jelena Maricic (University of Hawaii, High Energy Physics Group) The Deep Underground Neutrino Experiment (DUNE) is a next-generation long-baseline neutrino oscillation experiment currently under construction at the Sanford Underground Research Facility (SURF) in South Dakota, USA. DUNE will test the three-flavor neutrino paradigm in an unprecedented way, and will measure the neutrino mass ordering ... Read more
Speakers: Dr Shawn Dubey Detecting the redshifted 21-cm signal from the early universe requires separating an extremely faint cosmological signal from bright foreground emission and terrestrial radio-frequency interference (RFI), but flagging RFI is a big challenge. I will describe our use of weak supervision, a method that combines multiple imperfect flaggers to construct training labels ... Read more
Speakers: Dr Shawn Dubey (Brown University) Machine Learning (ML) has advanced rapidly over the past decade, transforming the way data-intensive sciences are conducted. High energy physics is distinctive among the physical sciences in its early adoption and deployment of new AI/ML methods, driven by extreme data volumes, complex event structures, and stringent real-time constraints. In ... Read more
Speakers: Prof. Yangheng Zheng (Chinese Academy of Sciences) Using a sensitive detection system developed by the MigdAl pRocess Validation by nEutruaL scattering (MERVEL) collaboration team, which combines a micropattern gasous detector with a semiconductor pixel readout chip, the apparatus effectively functions as a camera capable of imaging the single‑atom electron‑emission process. Using neutron–nucleus scattering, the team made ... Read more
Speakers: Asst. Prof. Niels Bidault (University of Hawaii at Manoa) The electron beam linear accelerator (linac) at the Free Electron Laser (FEL) Laboratory at the University of Hawai‘i at Mānoa is currently undergoing recommissioning. The facility was originally installed and operated under the direction of Prof. John Madey, pioneer of FEL science. The accelerator provides ... Read more
