ALPHA publishes first measurements of quantum effects in antimatter
ALPHA publishes first measurements of quantum effects in antimatter The ALPHA collaboration at CERN has reported the first measurements of fine structure effects and Lamb shift in the energy structure of antihydrogen that provide another test of comparison between antimatter and ordinary matter. The results, described in a paper published in Nature, show that these

PUMA: Exploring exotic nuclear phenomena with antimatter
PUMA: Exploring exotic nuclear phenomena with antimatter PUMA is a new experiment proposed at both the CERN AD and ISOLDE facilities, that would for the first time transport antiprotons trapped at AD/ELENA to ISOLDE, by carrying them in a trap loaded onto a truck. The antiprotons would then be used for nuclear physics experiments at

BASE probes antimatter – dark matter interaction
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 antiprotons. Their analysis constrained the value of the axion–antiproton interaction parameter in the range

ALPHA new results: pushing the limits in antimatter research
ALPHA new results: pushing the limits in antimatter research In a paper published this week in Nature, the ALPHA collaboration reports the most precise direct measurement of antimatter ever made, revealing the spectral structure of the antihydrogen atom in unprecedented accuracy. The result marks a new era of high precision tests between matter and antimatter

ALPHA experiment takes a closer look at antimatter
ALPHA experiment takes a closer look at antimatter The ALPHA collaboration at CERN in Geneva has scored another coup on the antimatter front by performing the first-ever spectroscopic measurements of the internal state of the antihydrogen atom. The results were published in www.nature.com/nature/journal/v548/n7665/pdf/nature23446.pdf“>https://www.nature.com/nature/journal/v548/n7665/pdf/nature23446.pdf“>Nature earlier this year in August. Their measurement showed the hyperfine splitting of

The BASE Experiment
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 antiprotons. These type of experiments provide stringent tests of the fundamental charge, parity, time invariance,
