Cooling a particle from a trap away

The BASE experiment, located at CERN’s Antiproton Deccelerator (AD) performs some of the most precise measurements with antimatter in the world – namely measuring the magnetic moment and charge-to-mass ratio of a single trapped antiproton. With…

BASE develops a new technique to detect ultralight dark matter.

In a recent work published in Physical Review Letters [1], the Baryon Antibaryon Symmetry Experiment (BASE) at CERN has placed new limits on a possible coupling between photons and hypothetical axionlike dark matter particles with masses between 2.…

A mobile antiproton reservoir for precision measurements

 The BASE collaboration has performed the most precise measurements of the fundamental properties of the antiproton in order to test CPT invariance as fundamental symmetry of the Standard Model [1, 2] and to search for dark matter-antimatter…

BASE probes antimatter - dark matter interaction

In a recent paper, the BASE collaboration presented results from a direct search for interactions of antimatter with dark matter and placed direct constraints on the interaction of ultralight axion-like particles (dark-matter candidates) with…

The BASE Experiment

BASE is a Japanese / German collaboration at the antiproton decelerator facility which was approved in 2013. The goal of the effort is to conduct Penning trap based high-precision investigations of the fundamental properties of protons and…
