Higgs II
- Kaoru Hagiwara
We explore the extent to which future precision measurements of the Standard Model (SM) parameters at the proposed $Z$-factories and Higgs factories may have impacts on new physics beyond the Standard Model, as illustrated by studying the Type-I two Higgs doublet model (Type-I 2HDM). We include the contributions from the heavy Higgs bosons at the tree-level and at the one-loop level in a full...
Searches for Higgs bosons in different extensions of the Standard Model (SM) are presented. These include models with additional scalar singlets, doublets, or triplets, and generic searches for models with couplings modified with respect to the SM or for non-SM Higgs boson decay channels. Results are based on data collected by the ATLAS in 2015 and 2016 at the LHC
We investigate the discovery potential for double Higgs production in a relatively overlooked $hh \to b \bar{b} W W^* \to b \bar{b} \ell^+ \ell^- + \;/\!\! \vec{P}_T$ final state. We supplement a novel kinematic method presented in Ref.[1] with jet images resulting from the $h\to b \bar b$ decay. Two $b$-quarks from the decay of the Higgs boson, are color-connected with each other. In...
I will discuss the di-Higgs production via gluon fusion within the context of Minimal Supersymmetric Standard Model (MSSM) and Next-to-Minimal Supersymmetric Standard Model (NMSSM). The calculation is based on the analytical expression of the leading order Feynman amplitudes (which includes both quark and squark loops), and therefore, both off-shell effects and interference between resonant...
We study the custodial Randall-Sundrum model with two Higgs doublets localized in the TeV brane. The scalar potential is CP- conserving and has a softly broken
Z2 symmetry. In the presence of a curvature-scalar mixing term the radion that
stabilizes the extra dimension now mixes with the two CP-even neutral scalars.
A goodness of fit of the LHC data on the properties of the light Higgs is...
