Testing Antimatter Couplings with Spectroscopy
Joerg Jaeckel, Lucas Puetter
We investigate how scalar-mediated potentials with Lorentz-violating couplings to Standard Model fermions affect spectroscopic observables in atoms and highly charged ions. Suitabl…

Restricting Sterile Neutrinos by Neutrinoless Double Beta Decay
Sudip Jana, Lucas Puetter, Alexei Yu. Smirnov
The bounds on parameters of the eV and higher scale sterile neutrinos from the decay have been refined and updated. We present a simple and compact analytic expression fo…
