Physics beyond the standard model with kaons at NA62
Also a search for an invisible dark photon A′ has been performed, exploiting the efficient photon-veto capability and high resolution tracking of the NA62. The signal stems from the chain $\mathit{K}$+ → $\pi ^{+} \pi^{0}$ followed by $ \pi^{0}$ → $\mathit{A}$′γ. No significant statistical excess ha...
