abstract
The first evidence for the Higgs boson decay to a $Z$ boson and a photon is presented, with a statistical significance of 3.4 standard deviations. The result is derived from a combined analysis of the searches performed by the ATLAS and CMS Collaborations with proton-proton collision data sets collected at the CERN Large Hadron Collider (LHC) from 2015 to 2018. These correspond to integrated luminosities of around 140 fb$^{-1}$ for each experiment, at a center-of-mass energy of 13 TeV. The measured signal yield is $2.2\pm0.7$ times the Standard Model prediction, and agrees with the theoretical expectation within 1.9 standard deviations.

Higgs boson precision analysis of two-Higgs-doublet models: Full LHC Run 1 and Run 2 data
The type-I two-Higgs-doublet model fits the combined LHC and Tevatron Higgs data best among the twelve scenarios considered, while wrong-sign type-II and type-IV scenarios fit worse than the Standard Model.

The Two Scales of New Physics in Loop-Induced Higgs Couplings
A deviation in the loop-induced Higgs couplings hgg, hγγ, or hZγ caused solely by new vectorlike fermions implies an upper bound on the mass scale of new bosons needed to restore perturbativity and vacuum stability.

Measurement of the Higgs boson decay to a low-mass dilepton system and a photon in $pp$ collisions at $\sqrt{s} =$ 13 and 13.6 TeV with the ATLAS detector
Combined Run-2+Run-3 ATLAS measurement of H to ell ell gamma (m_ll < 30 GeV) gives mu = 1.03 (+0.35/-0.32) with 3.4 sigma observed (3.3 sigma expected) significance, consistent with the Standard Model.

$CP$ violation in the $HZZ$ vertex and left-right asymmetries
Flavor-changing Z and Higgs couplings can induce CP-violating HZZ form factors up to about 10^-7, and a new asymmetry in Z* -> Z H is proposed to search for them.

Dark Matter and CP Violation in Some Symmetry-Constrained 3HDMs
S3-symmetric three-Higgs-doublet models allow dark matter in a 29-42 GeV window, exclude heavy candidates above 500 GeV, and admit MeV-scale light scalars, while continuous-symmetry variants produce mass-degenerate da...

Light quark contributions to Higgs decays
The authors claim the u, d, and s quark contributions to H→γγ and H→Zγ vanish exactly after non-perturbative pion effects are included, rather than being merely small.
