Fredy Jimenez, Diego Restrepo, Andr\'es Rivera
TL;DR
This paper develops a type-II two-Higgs-doublet model within noncommutative geometry that aligns with the observed 125 GeV Higgs mass and predicts additional scalar particles with masses above 350 GeV.
Contribution
It introduces a novel NCG-based two-Higgs-doublet model that achieves realistic Higgs mass predictions and explores its phenomenology.
Findings
Higgs mass compatible with 125 GeV
Extra scalars with masses above 350 GeV
Model remains within alignment limit without decoupling
Abstract
In noncommutative geometry (NCG) the spectral action principle predicts the standard model (SM) particle masses by constraining the scalar and Yukawa couplings at some heavy scale, but gives an inconsistent value for the Higgs mass. Nevertheless, the scalar sector in the NCG approach to the standard model, is in general composed of two Higgs doublets and its phenomenology remains unexplored. In this work, we present a type-II two-Higgs-doublet model in NCG, with a SM-like Higgs mass compatible with the 125~GeV experimental value and extra scalars within the alignment limit without decoupling with masses from 350 GeV.
