Summary: | A
bstract
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
-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. |
