title = "Searches for hidden sectors using K+→ π+X decays",
abstract = "Results from the study of the rare decays K+→π+νν¯, K+ → π+μ+μ− and K+ → π+γγ at the NA62 experiment at CERN are interpreted in terms of improved limits for BK+→π+X and coupling parameters of hidden-sector models, where X is a mediator. World-leading limits are achieved for dark photon, dark scalar and axion-like particle models.",
