We discuss axionlike particles (ALPs) within the framework of Higgs effective field theory, targeting
instances of close alignment of ALP physics with a custodial singlet character of the Higgs boson.
We tension constraints arising from new contributions to Higgs boson decays against limits from highmomentum
transfer processes that become under increasing control at the LHC. Going beyond leadingorder
approximations, we highlight the importance of multitop and multi-Higgs production for the pursuit
of searches for physics beyond the Standard Model extensions.
