In the presence of axions and axion-like particles (ALPs) that couple to the Standard Model via non-renormalisable dimension-5 operators, non-zero Wilson coefficients (WCs) of the Standard Model effective field theory (SMEFT) are induced by renormalisation group evolution. Since many of the SMEFT WCs are experimentally constrained, this ALP-SMEFT interference allows to derive indirect bounds...

In this talk, I review recent work developing dilaton effective field theory (EFT), which provides a framework for describing the Higgs boson as composite state. The EFT describes a multiplet of pseudo-Goldstone bosons which arise when an approximate global symmetry gets spontaneously broken, as well as a dilaton - a pseudo-Goldstone boson arising from the spontaneous breaking of an...

Dark photons are massive abelian gauge bosons that interact with ordinary photons via a kinetic mixing with the hypercharge field strength tensor. This theory is probed by a variety of different experiments and limits are set on a combination of the dark photon mass and kinetic mixing parameter. These limits can however be strongly modified by the presence of additional heavy degrees of...
