Twin Higgs with exact Z 2

open access: yesJournal of High Energy Physics, 2020
We present a novel mechanism for realistic electroweak symmetry breaking in Twin Higgs/neutral naturalness models where the Z 2 exchange symmetry can remain exactly unbroken.

Naturalness sum rules and their collider tests

open access: yesJournal of High Energy Physics, 2019
We present the most general sum rules reflecting the cancellation of ultraviolet divergences in the Higgs potential, which provide necessary conditions for any weakly-coupled extension of the Standard Model to be natural. There is a separate sum rule for

Testing naturalness at 100 TeV

open access: yesJournal of High Energy Physics, 2017
Solutions to the electroweak hierarchy problem typically introduce a new symmetry to stabilize the quadratic ultraviolet sensitivity in the self-energy of the Higgs boson.

Vacuum alignment in a composite 2HDM

open access: yesJournal of High Energy Physics, 2019
We study in detail the vacuum structure of a composite two Higgs doublet model based on a minimal underlying theory with 3 Dirac fermions in pseudo-real representations of the condensing gauge interactions, leading to the SU(6)/Sp(6) symmetry breaking ...

Constraining composite Higgs models using LHC data

open access: yesJournal of High Energy Physics, 2018
We systematically study the modifications in the couplings of the Higgs boson, when identified as a pseudo Nambu-Goldstone boson of a strong sector, in the light of LHC Run 1 and Run 2 data.

Relaxation of the composite Higgs little hierarchy

open access: yesJournal of High Energy Physics, 2017
We describe a composite Higgs scenario in which a cosmological relaxation mechanism naturally gives rise to a hierarchy between the weak scale and the scale of spontaneous global symmetry breaking.
