Overview

Search identifies upper limits on heavy resonances decaying into Higgs bosons in proton-proton collisions, suggesting new physics may exist.

Key Points

  • The research aims to search for heavy resonances decaying into pairs of Higgs bosons in proton-proton collisions.
  • Analyzed collision data from 2016-2018 collected at the LHC using the CMS detector.
  • Focused on final states involving one Higgs boson decaying into bottom quarks and the other into tau leptons.
  • Used large jet reconstruction to identify decay processes of Higgs bosons.
  • Set upper limits on production cross section for resonant HH production.
  • Observed data align with standard model background predictions.
  • Established the most sensitive limits on decays for mass range of 1.4 to 4.5 TeV.
  • Defined upper limits at 95% confidence level on the production cross section.
