abstract
A search for low-mass dilepton resonances in Higgs boson decays is conducted in the four-lepton final state. The decay is assumed to proceed via a pair of beyond the standard model particles, or one such particle and a Z boson. The search uses proton-proton collision data collected with the CMS detector at the CERN LHC, corresponding to an integrated luminosity of 137 fb$^{-1}$, at a center-of-mass energy $\sqrt{s} =$ 13 TeV. No significant deviation from the standard model expectation is observed. Upper limits at 95% confidence level are set on model-independent Higgs boson decay branching fractions. Additionally, limits on dark photon and axion-like particle production, based on two specific models, are reported.

Search for an exotic decay of the 125 GeV Higgs boson to a pair of light pseudoscalars in the final state of two muons and two c-quarks in proton-proton collisions at $\sqrt{s} = 13\;\text{TeV}$ with CMS Open Data
The first search for h->aa->mumu cc in LHC data sets 95% CL upper limits down to 3.3e-4 on sigma/sigma_SM times the branching fraction, excluding new parameter space in 2HDM+S models.

Light scalars within the $\mathcal{CP}$-conserving Aligned-two-Higgs-doublet model
All seven light-scalar scenarios of the CP-conserving aligned two-Higgs-doublet model contain sizeable parameter regions compatible with current collider and flavour data, with the lightest new scalars bounded by LEP ...

Limits on an Exotic Higgs Decay From a Recast ATLAS Four-Lepton Analysis
By recasting ATLAS's Z to three dark photon analysis, the authors set the best limits to date on the exotic Higgs decay chain H to aa to VVVV to eight fermions, bounding the branching fraction to roughly 4e-5 to 1e-4.

Charged Higgs Search in 2HDM
Updated LHC and LEP constraints on charged Higgses show that H+ to A W and H+ to H W decay channels are complementary to fermionic channels and extend the search reach in the Type-L 2HDM.
