Probing invisible particles with charm

Gudrun Hiller, Dominik Suelmann

We point out opportunities to probe invisible particles, left- and right-handed neutrinos, axion-like particles (ALPs) and dark photons $(Z^{'})$ with rare decays of charm hadro…

New opportunities for rare charm from $Z \to c c ˉ$ decays

Angelo Di Canto, Tabea Hacheney, Gudrun Hiller +4

We analyze the potential of rare charm decays as probes of new physics at a high-luminosity flavor facility operating at the $Z$ pole, such as the FCC-ee or CEPC. In particular, we…

BSM reach of rare charm decays, including the rising star $Λ_{c} \to p μ^{+} μ^{-}$

Hector Gisbert, Gudrun Hiller, Dominik Suelmann

We perform the first global fit of rare charm transitions using recent data on $D^{0} \to μ^{+} μ^{-}$ , $D^{+} \to π^{+} μ^{+} μ^{-}$ , $Λ_{c} \to p μ^{+} μ^{-}$ and $D^{0} \to π^{+} π^{-} μ^{+} μ^{-}$ decays, including angul…
