Room-temperature emission of muonium from aerogel and zeolite targets
A. Antognini, P. Crivelli, L. Gerchow +12
A low-emittance, high-intensity atomic beam of muonium () using superfluid helium as muon-to-muonium converter is being developed at the Paul Scherre…
New bounds from positronium decays on massless mirror dark photons
C. Vigo, L. Gerchow, B. Radics +3
We present the results of a search for a hidden mirror sector in positronium decays with a sensitivity comparable with the bounds set by the prediction of the primordial He a…
A new approach for the ortho-positronium lifetime determination in a vacuum cavity
C. Vigo, M. Raajimakers, L. Gerchow +3
Currently, the experimental uncertainty for the determination of the ortho-positronium (o-Ps) decay rate is at 150 ppm precision; this is two orders of magnitude lower than the the…
Positronium in MOFs: the Atom out of the box
P. Crivelli, D. Cooke, B. Barbiellini +6
Recently, evidence for positronium (Ps) in a Bloch state in self-assembled metal--organic frameworks (MOFs) has been reported [Dutta et al., Phys. Rev. Lett. 110, 197403 (2013)]. I…
