The role of the top Yukawa coupling in triple Higgs production at the LHC
Luca Panizzi
TL;DR
This paper investigates how variations in the top Yukawa coupling influence triple Higgs production at the LHC, showing significant effects on total cross-section but minimal impact on distribution shapes.
Contribution
It quantifies the impact of top Yukawa coupling variations on triple Higgs production, providing insights into potential experimental sensitivities.
Findings
Total cross-section is highly sensitive to Yukawa coupling variations.
Distribution shapes of global observables are relatively unaffected.
Experimental measurements could constrain the top Yukawa coupling.
Abstract
In this letter I quantify the effects of varying the top Yukawa coupling in the process of production of three Higgs bosons at the LHC. Modifications of the coupling within experimentally observed ranges have a sizeable impact on the total cross-section, but do not have large effects on the distributions of the invariant mass of the three-Higgs system and other global observables.
