SUMMARY:Searches for heavy resonances decaying into two Higgs bosons (
 HH) in the bb tau tau final state using Run 3 data from the CMS experi
 ment.\, Preliminary Exam\, Mitanshu Thakore
DESCRIPTION:The talk will focus on searches for heavy resonances decay
 ing into a pair of Higgs bosons predicted by beyond the Standard Model
  theories. The search targets final states where one Higgs boson decay
 s into a pair of tau leptons and the other into a pair of bottom quark
 s: X→HH→bb ττ. The analysis uses proton–proton collision dat
 a at a center-of-mass energy of 13.6 TeV\, collected with the Compact 
 Muon Solenoid experiment at the Large Hadron Collider during Run 3 (20
 22–2026). These final states are particularly challenging because\, 
 for heavy resonances\, the Higgs bosons are produced with large Lorent
 z boosts. As a result\, their decay products are separated by a small 
 angle in space and appear highly collimated in the detector. Due to th
 is collimation\, a single large-cone (AK8) jet is used to reconstruct 
 the H→bb decay. For the H→ττ decay\, the tau-lepton pair is also
  highly boosted and collimated. Depending on the event topology\, the 
 Taus may be reconstructed either within a single large jet or as two i
 solated tau leptons. The search is performed by scanning the distribut
 ion of the reconstructed resonance mass and looking for a local excess
  in data compared to the background prediction.
