Constraining the real singlet extension of the Standard Model: implications for vacuum stability

Moritz Bosse, Gudrun Hiller, Daniel Litim +4

The paper investigates the addition of a real singlet scalar to the Standard Model, analyzing theoretical and experimental constraints and its impact on electroweak phase transitio…

Constraining the real scalar singlet extension of the SM

Moritz Bosse, Gudrun Hiller, Daniel Litim +4

The real scalar singlet extension of the standard model provides a minimal framework in which the Higgs sector can realise a strong first-order electroweak phase transition and imp…

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…

Vacuum Stability in the Standard Model and Beyond

Gudrun Hiller, Tim HÃ¶hne, Daniel F. Litim +1

We revisit the stability of the Standard Model vacuum, and investigate its quantum effective potential using the highest available orders in perturbation theory and the most accura…

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 $I^_{c} \to p I^¼^{+} I^¼^{-}$

Hector Gisbert, Gudrun Hiller, Dominik Suelmann

We perform the first global fit of rare charm transitions using recent data on $D^{0} \to I^¼^{+} I^¼^{-}$ , $D^{+} \to I ¨ ^{+} I^¼^{+} I^¼^{-}$ , $I^_{c} \to p I^¼^{+} I^¼^{-}$ and $D^{0} \to I ¨ ^{+} I ¨ ^{-} I^¼^{+} I^¼^{-}$ decays, inc…
