Description

Composite Higgs models describe a strongly coupled gauge fermion sector which extends the Standard Model, introducing the Higgs boson as a new bound state arising due to the breaking of a global (flavour) symmetry. These models will be accompanied by light states generated by the same dynamics, the detection of which may present the first signs of compositeness. The subject of this work, a pseudo-scalar resulting from the breaking of a U(1) symmetry, is one such state. We study the phenomenology of this scalar, making a case for targeted low mass searches at future lepton colliders, with a focus on production of the pseudo-scalar at the FCC-ee collider with a subsequent decay to a di-tau pair.
