[Physical-sciences] PSD Announcement: November Mixer (November14th)

Fri Nov 7 14:37:33 PST 2025

Hello, PSD Member!

Delighted to share that our next mixer is this Friday November 14th, at 2:30pm online and in the Auditorium!
The tentative agenda and connection information is below.

In-person attendees: Please pre register your attendance Mixer Attendance - November 14th 2025 – Fill out form<https://forms.office.com/r/YiV9NQUvfg>.
This information helps us with planning future mixers (the food and drink order specifically), and it also satisfies AP’s requirement of listing attendees when I reconcile the catering bill.

Science Talk Abstract;
The identical gravitational behaviour of matter and antimatter is ensured by the weak equivalence principle, a building block of general relativity. However, a direct verification of this equality via the observation of antimatter in a gravitational field is technically challenging. The ALPHA-g experiment at CERN recently made the first measurement of Earth’s gravity on trapped antihydrogen atoms, reporting a downwards acceleration compatible with that of matter. The antihydrogen gravitational acceleration is inferred from the location of the annihilations when anti-atoms are released from the trap. I will present the method and results of this experiment, with a focus on the particle detectors and techniques used to reconstruct the annihilation positions.
