The Flavor of UV Physics
Sebastian Bruggisser, Ruth Schäfer, Danny van Dyk +1
New physics not far above the TeV scale should leave a pattern of virtual effects in observables at lower energies. What do these effects tell us about the flavor structure of a UV…

Probing dark sectors with long-lived particles at BELLE II
Anastasiia Filimonova, Ruth Schäfer, Susanne Westhoff
We propose a new search for light scalar singlets in rare meson decays. For tiny interactions, the scalar is long-lived at detector scales and decays into displaced pairs of lepton…
