Relaxion and light (pseudo)scalars at the HL-LHC and lepton colliders
Abstract We study the potential of future lepton colliders, running at the Z-pole and above, and the High-Luminosity LHC to search for the relaxion and other light scalars ϕ. We investigate the interplay of direct searches and precision observables for both C P $$ \mathcal{C}\mathcal{P} $$ -even and...

Summary: | Abstract We study the potential of future lepton colliders, running at the Z-pole and above, and the High-Luminosity LHC to search for the relaxion and other light scalars ϕ. We investigate the interplay of direct searches and precision observables for both C P $$ \mathcal{C}\mathcal{P} $$ -even and -odd couplings. In particular, precision measurements of exotic Z-decays, Higgs couplings, the exotic Higgs decay into a relaxion pair and associated Zϕ and γϕ production are promising channels to yield strong bounds. |
