The project aims to measure the antiproton and pion masses with unprecedented precision using laser spectroscopy of specific helium atoms. This research will enhance our understanding of fundamental physical constants.
This proposal has two objectives.
First, I propose to measure the antiproton mass relative to the electron mass with a fractional precision of 0.1 ppb by carrying out sub-Doppler two-photon laser spectroscopy of antiprotonic helium atoms.
The antiproton mass would then be better known than the proton mass.
The (anti)proton-to-electron mass ratio is regarded as a one of several fundamental physical constants which, like the fine structure constant α, is a dimensionless quantity of nature that can…
