GermanIum Array for Non-destructive Testing (GIANT) setup for Muon Induced X-ray Emission (MIXE) at the Paul Scherrer Institute
Lars Gerchow, Sayani Biswas, Gianluca Janka +7
The usage of muonic X-rays to study elemental properties like nuclear radii ranges back to the seventies. This triggered the pioneering work at the Paul Scherrer Institute (PSI), d…
Precision measurement of the Lamb shift in Muonium
B. Ohayon, G. Janka, I. Cortinovis +10
We report a new measurement of the Lamb shift in Muonium using microwave spectroscopy. Our result of MHz comprises an order of…
Intense beam of metastable Muonium
G. Janka, B. Ohayon, Z. Burkley +10
Precision spectroscopy of the Muonium Lamb shift and fine structure requires a robust source of 2S Muonium. To date, the beam-foil technique is the only demonstrated method for cre…
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…
First search for invisible decays of ortho-positronium confined in a vacuum cavity
C. Vigo, L. Gerchow, L. Liszkay +2
The experimental setup and results of the first search for invisible decays of ortho-positronium (o-Ps) confined in a vacuum cavity are reported. No evidence of invisible decays at…
