Implications of the absence of high-mass radion signals
Aqeel Ahmed, Barry M. Dillon, Bohdan Grzadkowski +2
Given the disappearance of the 750 GeV di-photon LHC signal and the absence of signals at high mass in this and other channels, significant constraints on the mixed Higgs-radion of…
Scrutinizing the Alignment Limit in Two-Higgs-Doublet Models. Part 2: GeV
Jérémy Bernon, John F. Gunion, Howard E. Haber +2
In the alignment limit of a multi-doublet Higgs sector, one of the Higgs mass eigenstates aligns in field space with the direction of the scalar field vacuum expectation values, an…
Higgs dark matter from a warped extra dimension
Aqeel Ahmed, Bohdan Grzadkowski, John F. Gunion +1
We present a 5D -symmetric IR-UV-IR model with a {\it warped KK-parity} under which the bulk fields have towers of either even or odd KK-modes. We show that this $\ma…
Radius stabilization and dark matter with a bulk Higgs in warped extra dimension
Aqeel Ahmed, Bohdan Grzadkowski, John F. Gunion +1
We employ an bulk Higgs doublet as the stabilization field in Randall-Sundrum model with appropriate bulk and brane-localized potentials. The gauge hierarchy problem can be…
Isospin-violating dark-matter-nucleon scattering via two-Higgs-doublet-model portals
Aleksandra Drozd, Bohdan Grzadkowski, John F. Gunion +1
We show that in a multi-Higgs model in which one Higgs fits the LHC 125 GeV state, one or more of the other Higgs bosons can mediate DM-nucleon interactions with maximal DM isospin…
Scrutinizing the Alignment Limit in Two-Higgs-Doublet Models. Part 1: GeV
Jérémy Bernon, John F. Gunion, Howard E. Haber +2
In the alignment limit of a multi-doublet Higgs sector, one of the Higgs mass eigenstates aligns with the direction of the scalar field vacuum expectation values, and its couplings…
Higgs Dark Matter from a Warped Extra-Dimension -- the truncated-inert-doublet model
Aqeel Ahmed, Bohdan Grzadkowski, John F. Gunion +1
We construct a 5D -symmetric model with three D3-branes: two IR ones with negative tension located at the ends of an extra-dimensional interval and a UV-brane with po…
Light Higgs bosons in Two-Higgs-Doublet Models
Jeremy Bernon, John F. Gunion, Yun Jiang +1
We explore the possibilities in two-Higgs-doublet models (2HDMs) of Type I and Type II for Higgs states with mass below about 60 GeV, i.e. less than half of the ~125 GeV mass of th…
