Search for Higgs boson pair production in the $\mathrm{b\bar{b}WW}$ decay channel with two leptons in the final state using proton-proton collision data at $\sqrt{s}$ = 13.6 TeV
A search for Higgs boson pair production is presented, targeting final states where one Higgs boson decays to a pair of bottom quarks and the other Higgs boson decays to two W bosons, both of which decay leptonically, to an electron or a muon, and a neutrino. For the first time, the search is conducted with proton-proton collision data from the LHC at $\sqrt{s}$ = 13.6 TeV, recorded with the CMS detector in 2022 and 2023 and corresponding to an integrated luminosity of 62 fb$^{-1}$. The results are consistent with the standard model predictions. An upper limit of 12.0 times the standard model prediction at 95% confidence level is set on the Higgs boson pair production cross section, with an expected limit of 18.5. The results are also used to constrain the strength of the trilinear self-coupling of the Higgs boson, as well as of the quartic coupling between two Higgs bosons and two vector bosons.

Measurements of inclusive and differential cross sections for Higgs boson production with decay to four leptons in proton-proton collisions at 13.6 TeV
Measurements of Higgs boson ($\mathrm{H}$) production cross sections in the four-lepton ($4\ell, \ell=\mathrm{e},\mu$) final state at a center-of-mass energy $\sqrt{s}=13.6\,\mathrm{TeV}$ are presented. These measurements are based on data collected with the CMS detector at the CERN LHC between 2022 and 2024, corresponding to an integrated luminosity of $171\,\mathrm{fb}^{-1}$. Cross sections are measured in a fiducial region closely matching the experimental acceptance, both inclusively and differentially, as a function of a range of observables. Dedicated measurements targeting the production of the Higgs boson via vector boson fusion are also performed. The $\mathrm{H}\to\mathrm{ZZ}\to 4\ell$ inclusive fiducial cross section is measured to be $\sigma_\mathrm{fid} = 3.11^{+0.22}_{-0.22}(\mathrm{stat.})^{+0.14}_{-0.12}(\mathrm{syst.})\, \mathrm{fb}$, in agreement with the standard model expectation of $3.05^{+0.17}_{-0.22}\, \mathrm{fb}$.

Search for Higgs boson production at high transverse momentum in the WW decay channel in proton-proton collisions at $\sqrt{s}$ = 13 TeV
A search for Higgs boson (\PH) production at high transverse momentum ($p_\mathrm{T}$) in the WW decay channel is presented. The analysis uses proton-proton collisions at $\sqrt{s}$ = 13 TeV recorded by the CMS experiment in 2016$-$2018, corresponding to an integrated luminosity of 138 fb$^{-1}$. The visible decay products of the Higgs boson are reconstructed as a single large-radius jet with one isolated lepton or none (1$\ell$ and 0$\ell$, respectively; $\ell$ = e, $μ$). The \PH-candidate jets are identified using an advanced transformer-based algorithm and are calibrated with the Lund jet plane reweighting technique. The 1$\ell$ channel is further split into gluon fusion, vector boson fusion, and associated production with hadronically decaying vector boson categories, while the 0$\ell$ channel considers all production processes inclusively. The measured cross section times the H $\to$ WW branching fraction relative to the standard model expectation is $μ$ = $-$0.19$^{+0.48}_{-0.46}$, indicating no evidence of a signal above the background. This measurement represents the first dedicated study of highly Lorentz-boosted H $\to$ WW decays, complementing earlier searches for high-$p_\mathrm{T}$ Higgs boson in other decay channels.

A search for Higgs boson (H) production at high transverse momentum ($ p_{\mathrm{T}} $) in the WW decay channel is presented. The analysis uses proton-proton collisions at $ \sqrt{s}= $ 13 TeV recorded by the CMS experiment in 2016--2018, corresponding to an integrated luminosity of 138 fb$ ^{-1} $. The visible decay products of the Higgs boson are reconstructed as a single large-radius jet with one isolated lepton or none (1 $ \ell $ and 0 $ \ell $, respectively; $ \ell=\mathrm{e},\mu $). The H-candidate jets are identified using an advanced transformer-based algorithm and are calibrated with the Lund jet plane reweighting technique. The 1 $ \ell $ channel is further split into gluon fusion, vector boson fusion, and associated production with hadronically decaying vector boson categories, while the 0 $ \ell $ channel considers all production processes inclusively. The measured cross section times the $ \mathrm{H} \to \mathrm{W} \mathrm{W} $ branching fraction relative to the standard model expectation is $ \mu = - $ 0.19 $ ^{+0.48}_{-0.46} $, indicating no evidence of a signal above the background. This measurement represents the first dedicated study of highly Lorentz-boosted $ \mathrm{H} \to \mathrm{W} \mathrm{W} $ decays, complementing earlier searches for high-$ p_{\mathrm{T}} $ Higgs boson in other decay channels.

Search for a narrow resonance with a mass between 10 and 70 GeV decaying to a pair of photons in proton-proton collisions at $\sqrt{s}$ = 13 TeV
The existence of a new spin-zero particle with a mass below the electroweak scale is predicted by several theoretical models. Searches for resonant production of photon pairs at the LHC are able to probe these models. We present a search for a narrow resonance produced through gluon fusion that decays into a pair of photons with an invariant mass between 10 and 70 GeV, using a proton-proton collision data set from the CMS experiment. This data set, corresponding to an integrated luminosity of 54.4 fb$^{-1}$, was recorded in 2018 at a center-of-mass energy of 13 TeV using a newly introduced diphoton trigger that enabled exploration of the low-mass diphoton spectrum. No significant excess above the expected background is observed. Upper limits are set on the product of the gluon fusion production cross section and the branching fraction of the diphoton decay of a narrow resonance. An interpretation of these limits within an effective field theory framework for axion-like particles is also provided.
