Abstract: (arXiv)

A search for exotic decays of the 125 GeV Higgs boson into a pair of new spin-0 particles,

H \to aa

, where one decays into a photon pair and the other into a

\tau

-lepton pair, is presented. Both

\tau

-leptons are reconstructed in the hadronic decay modes using a dedicated tagger for collimated

\tau

-lepton pairs. The search uses 140 fb

^{-1}

of proton-proton collision data at a centre-of-mass energy of

\sqrt{s}=13

TeV recorded between 2015 and 2018 by the ATLAS experiment at the Large Hadron Collider. The search is performed in the mass range of the

a

boson between 10 GeV and 60 GeV. No significant excess of events is observed above the Standard Model background expectation. Upper limits at 95% confidence level are set on the branching ratio of the Higgs boson to the

\gamma\gamma\tau\tau

final state,

\mathcal{B}(H\to aa\to \gamma\gamma\tau\tau)

, ranging from 0.2% to 2%, depending on the

a

-boson mass hypothesis.
