New bound on the vectorial axion-down-strange coupling from $K^{+} \to I ¨ ^{+} I^½ I^ˉ ½$ data

Diego Guadagnoli, Axel Iohner, Cristina Lazzeroni +3

We reinterpret publicly available $K^{+} \to I ¨ ^{+} I^½ I^ˉ ½$ data collected by NA62 from 2016 to 2024 to constrain the fundamental vectorial coupling of the QCD axion to down and stra…

Kaon Physics: A Cornerstone for Future Discoveries

Jason Aebischer, Atakan Tugberk Akmete, Riccardo Aliberti +153

The kaon physics programme, long heralded as a cutting-edge frontier by the European Strategy for Particle Physics, continues to stand at the intersection of discovery and innovati…

Probing QCD Axions or Axion-like Particles in three-body $K$ Decays

Mael Cavan-Piton, Diego Guadagnoli, Axel Iohner +2

Two-body decays like $K \to I ¨ a$ rank among the most constraining collider probes for new, low-mass, feebly interacting pseudoscalar particles $a$ . We explore an alternative class…
