Synthesis of a high intensity, superthermal muonium beam for gravity and laser spectroscopy experiments

Jesse Zhang, Aldo Antognini, Marek Bartkowiak +8

The universality of free fall, a cornerstone of Einstein's theory of gravity, has so far only been tested with neutral composite states of first-generation Standard Model (SM) part…

Phase space compression of a positive muon beam in two spatial dimensions

A. Antognini, N. J. Ayres, I. Belosevic +13

We present the first demonstration of simultaneous phase space compression in two spatial dimensions of a positive muon beam, the first stage of the novel high-brightness muon beam…

The helion charge radius from laser spectroscopy of muonic helium-3 ions

The CREMA Collaboration, Karsten Schuhmann, Luis M. P. Fernandes +37

Hydrogen-like light muonic ions, in which one negative muon replaces all the electrons, are extremely sensitive probes of nuclear structure, because the large muon mass increases t…

Diffusion of muonic hydrogen in hydrogen gas and the measurement of the 1 hyperfine splitting of muonic hydrogen

J. Nuber, A. Adamczak, M. Abdou Ahmed +46

The CREMA collaboration is pursuing a measurement of the ground-state hyperfine splitting (HFS) in muonic hydrogen (p) with 1 ppm accuracy by means of pulsed laser spectroscopy.…
