Bounds on scalar masses in two Higgs doublet models
P.M. Ferreira, D.R.T. Jones
TL;DR
This paper analyzes stability and perturbativity bounds in two-Higgs doublet models, incorporating experimental LEP constraints to tightly restrict the lighter Higgs mass, providing comprehensive theoretical and experimental insights.
Contribution
It offers a detailed analysis of theoretical bounds in various two-Higgs doublet models and integrates LEP experimental data to refine Higgs mass constraints.
Findings
Stability and perturbativity bounds are established for different model variants.
LEP data imposes strict lower limits on the lighter Higgs mass.
The analysis covers both CP-conserving and CP-violating scenarios.
Abstract
A thorough analysis of stability and perturbativity bounds is performed in several versions of the two-Higgs doublet model, for both CP-conserving and spontaneously broken CP minima. LEP results further aid in establishing very strict constraints on the mass of the lighter Higgs particle.
