Description
The exploration of Higgs boson self-coupling has remained a key focus of research since its discovery in 2012. The Higgs boson pair production in association with a top-quark pair, ttHH, is one of the rare and unexplored processes in the Standard Model (SM), with a cross-section of 0.756 (0.860) fb at 13 (13.6) TeV. Due to the strong Yukawa coupling of the top quark, ttHH is highly sensitive to potential Beyond Standard Model (BSM) physics. Additionally, it provides valuable insights into BSM interactions described by Effective Field Theories (EFTs).
