Antihydrogen, the antimatter counterpart of hydrogen, provides a unique platform for testing fundamental symmetries in nature. One of its key properties, the ground-state hyperfine splitting (GSHFS), serves as a sensitive probe for Charge-Parity-Time (CPT) symmetry. In hydrogen, this splitting is known to a precision of 1.4 parts in 10¹² [1], offering a precise benchmark for comparison. As the...

Short Talk (15min)

The antihydrogen atom (the antimatter counterpart of a standard hydrogen atom) provides a unique testbed for probes of CPT invariance and the Weak Equivalence Principle (WEP) due to its mathematical simplicity and neutral charge respectively. However, prior to performing any such tests the antiatoms must first be synthesised from their constituent particles.
Presented here are the recent...

Short Talk (15min)

In our cryogenic multi-Penning trap experiment, we aim to contribute to high-precision (anti-)proton $g$-factor$^{[1,2]}$ measurements pursued by the BASE collaboration, providing stringent tests of CPT symmetry$^{[3]}$. To reach precision at the parts-per-trillion level and to gain access to SME coefficients currently unreachable with existing techniques, we are implementing techniques based...
