DESCRIPTION:Extensions of the Standard Model\, such as the Minimal Supersy
 mmetric Standard Model (MSSM)\, predict an extended Higgs sector with addi
 tional neutral heavy Higgs bosons (H/A). These particles can have enhanced
  couplings to down-type fermions at large tan⁡β.\n\nThis talk presents 
 a search for heavy Higgs bosons decaying to tau lepton pairs in the fully 
 hadronic (τ-had τ-had​) final state using ATLAS Run~2 and Run~3 data. 
 The analysis uses the topology of two high-pT taus produced back-to-back 
 in the transverse plane. The dominant multijet background is estimated usi
 ng a data-driven method\, while other backgrounds are modeled using simula
 tion. A statistical analysis is performed using the total transverse mass 
 distribution\, and the results are interpreted as upper limits on the prod
 uction cross section times branching ratio.\n\nhttps://indico.ific.uv.es/e
