Martin Wolfgang Winkler
The simplest extension of the standard model consists in adding one singlet scalar field which mixes with the Higgs boson. $\mathcal{O}(\mathrm{GeV})$ masses of the new scalar carry strong motivation from relaxion, dark matter and inflation models. The decay of a GeV scalar is, however, notoriously ...
