No 2, § Instituto de Fisica Teorica, IFT-UAM/CSIC, Cantoblanco, 28049, Madrid, Spain Departamento de Fisica Teorica, Universidad Autonoma de Madrid, Cantoblanco, 28049, Madrid, Spain We study exotic Higgs decays h → ZX, with X an invisible beyond the Standard Model (SM) particle, resulting in a semi-dark final state. Such exotic Higgs decays may occur in theories of axionlike-particles (ALPs), dark photons or pseudoscalar…

### Simplified dark matter models with two Higgs doublets: I. Pseudoscalar mediators

• Physics
• 2017
A bstractWe study a new class of renormalisable simplified models for dark matter searches at the LHC that are based on two Higgs doublet models with an additional pseudoscalar mediator. In contrast

### Collider probes of axion-like particles

• Physics
• 2017
A bstractAxion-like particles (ALPs), which are gauge-singlets under the Standard Model (SM), appear in many well-motivated extensions of the SM. Describing the interactions of ALPs with SM fields by

### Probing ALP-sterile neutrino couplings at the LHC

• Physics
• 2019
In this work, prospects to probe an overlooked facet of axion-like particles (ALPs) -- their potential couplings to sterile neutrinos -- are presented. We found that mono-photon searches have the

### HiggsSignals-2: probing new physics with precision Higgs measurements in the LHC 13 TeV era

• Physics
• 2020
The program HiggsSignals confronts the predictions of models with arbitrary Higgs sectors with the available Higgs signal rate and mass measurements, resulting in a likelihood estimate. A new version

Abstract We propose a new search for Axion-Like Particles (ALPs), targeting Vector Boson Scattering (VBS) processes at the LHC. We consider nonresonant ALP-mediated VBS, where the ALP participates

• 2011
No evidence for processes in the mass range m(A⁰) ≤ 9.2 GeV and m(χ) ≤ 4.5 GeV is found in the sample of 98 × 10⁶ Υ(2S) decays collected with the BABAR detector and stringent limits on new physics models that contain light dark matter states are set.

### Search for a light pseudoscalar Higgs boson in the boosted μμττ final state in proton-proton collisions at √s = 13 TeV

• Physics
• 2020
A search for a light pseudoscalar Higgs boson (a) decaying from the 125 GeV (or a heavier) scalar Higgs boson (H) is performed using the 2016 LHC proton-proton collision data at $$\sqrt{s}$$ =
