Search for Higgs boson exotic decays into Lorentz-boosted light bosons in the four-$\ddot{I}„$ final state at $\sqrt{s}=13$ TeV with the ATLAS detector

ATLAS Collaboration

A search for exotic decays of the Higgs boson into a pair of low-mass scalars that subsequently decay into $\ddot{I}„$-leptons, $H\to aa\to \ddot{I}{„}^{+}\ddot{I}{„}^{-}\ddot{I}{„}^{+}\ddot{I}{„}^{-}$, is presented…
