Relaxion and light (pseudo)scalars at the HL-LHC and lepton colliders

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 $ \mathcal{C}\mathcal{P} $ -even and -odd couplings...

description 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 $ \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.

In particular, precision measurements of exotic Z-decays, Higgs couplings, the exotic Higgs decay into a relaxion pair and associated $Z\phi$ and $\gamma \phi$ production are promising channels to yield strong bounds.arXiv:1807.10842oai:cds.cern.ch:26414702018-07-27
