TL;DR
This paper performs a comprehensive global fit of Type-II 2HDMs, assessing how future collider measurements could refine or constrain the model's parameter space using current and projected experimental data.
Contribution
It provides the first detailed analysis of the impact of future collider precision measurements on the 2HDM parameter space using the GAMBIT framework.
Findings
Current constraints limit 2HDM parameters significantly.
Future colliders like HL-LHC, CEPC, ILC, FCC-ee can further probe the model.
The study highlights the potential to exclude or discover parts of the 2HDM parameter space.
Abstract
In this work, we summarize a global fit study of Type-II two Higgs doublet models (2HDM), and explore the impact of future SM-like Higgs and Z-pole precision measurements on the allowed parameter space. The work is based on the study results of a global fit of 2HDMs with the tool GAMBIT, utilising various current constraints including theoretical constraints (unitarity, perturbativity and vacuum stability), Higgs searches at colliders, electroweak physics and flavour constraints. We further investigate the ability of future facilities, such as the HL-LHC, CEPC, ILC and FCC-ee to explore the 2HDM parameter space.
