Abstract: 
We revisit the Higgs portal vector dark matter model including a hidden sector Higgs field that generates the mass of the vector dark matter. The model becomes renormalizable and has two scalar bosons, the mixtures of the standard model (SM) Higgs and the hidden sector Higgs bosons. The strong bound from direct detection such as XENON100 is evaded due to the cancellation mechanism between the contributions from two scalar bosons. As a result, the model becomes still viable in large range of dark matter mass, contrary to some claims in the literature. The Higgs properties are also affected, the signal strengths for the Higgs boson search being universally suppressed relative to the SM value, which could be tested at the LHC in the future.

Search for invisible decays of a Higgs boson produced through vector boson fusion in proton-proton collisions at root s=13 TeV

Albert M. Sirunyan, +2301 more
- 10 Jun 2019 - 
TL;DR: In this article, a search for invisible decays of a Higgs boson via vector boson fusion is performed using proton-proton collision data collected with the CMS detector at the LHC in 2016 at a center-of-mass energy root s = 13 TeV, corresponding to an integrated luminosity of 35.9fb(-1).

Searches for invisible decays of the Higgs boson in pp collisions at √s = 7, 8, and 13 TeV

Vardan Khachatryan, +2328 more
- 28 Feb 2017 - 
TL;DR: In this paper, an upper bound on the branching fraction of the Higgs boson decay to invisible particles, as a function of the assumed production cross-sections, was established, and the results were also interpreted in the context of Higgs-portal dark matter models.

Toward (finally!) ruling out Z and Higgs mediated dark matter models

Miguel Escudero, +5 more
- 15 Dec 2016 - 
TL;DR: In this paper, the authors focus on the subset of WIMP models in which the dark matter annihilates in the early universe through couplings to either the Standard Model Z or the Higgs boson, and find that the overwhelming majority of these dark matter candidates are already ruled out by existing experiments.

Dark Matter through the Higgs portal

Giorgio Arcadi, +2 more
- 03 Feb 2020 - 
TL;DR: In this paper, the authors review scenarios in which the particles that account for the Dark Matter (DM) in the Universe interact only through their couplings with the Higgs sector of the theory, the so-called Higgs-portal models.

Weak Interactions with Lepton-Hadron Symmetry

Sheldon L. Glashow, +2 more
- 01 Oct 1970 - 
TL;DR: In this paper, a model of weak interactions was proposed in which the currents are constructed out of four basic quark fields and interact with a charged massive vector boson, and it was shown that the leading divergences do not violate any strong-interaction symmetry.
