Search for decays of the Higgs boson into pair-produced pseudoscalar particles decaying into $τ^+τ^-τ^+τ^-$ using $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector

A search for a pair of low-mass pseudoscalars $a$ that promptly decay into $τ$-leptons is presented using 140 fb$^{-1}$ of proton-proton collision data at $13$ TeV centre-of-mass energy recorded with the ATLAS detector at the Large Hadron Collider. The result is used …
