abstract

Measurements of Higgs boson properties in the H $\to\gamma\gamma$ decay channel are reported. The analysis is based on data collected by the CMS experiment in proton-proton collisions at $\sqrt{s} =$ 13 TeV during the 2016 LHC running period, corresponding to an integrated luminosity of 35.6 fb$^{-1}$. Allowing the Higgs mass to float, the measurement yields a signal strength relative to the standard model prediction of 1.18 $^{+0.17}_{-0.14} =$ 1.18 $^{+0.12}_{-0.11}$ (stat) $^{+0.09}_{-0.07}$ (syst) $^{+0.07}_{-0.06}$ (theo), which is largely insensitive to the exact Higgs mass around 125 GeV. Signal strengths associated with the different Higgs boson production mechanisms, couplings to bosons and fermions, and effective couplings to photons and gluons are also measured.

  1. Resolving the $(g-2)_{\mu}$ and $B$ anomalies with leptoquarks and a dark Higgs boson

    hep-ph 2019-08 conditional novelty 5.0 of 10

    A model with a light dark Higgs and TeV-scale leptoquarks can simultaneously explain the muon g-2 and B decay anomalies, and predicts rare B, K, and Higgs decays within reach of current experiments.

  2. Constraining new physics from Higgs measurements with Lilith: update to LHC Run 2 results

    hep-ph 2019-08 conditional novelty 5.0 of 10

    Lilith-2.0 updates the Higgs signal-strength likelihood tool to ATLAS and CMS Run 2 data, adding variable Gaussian and Poisson likelihoods, arbitrary-dimensional correlations, and new global coupling fits.

  3. A measurement of the Higgs boson mass in the diphoton decay channel in proton-proton collisions at $\sqrt{s}$ = 13 TeV

    hep-ex 2026-07 accept novelty 4.0 of 10

    CMS measures the Higgs mass in H→γγ with 138 fb⁻¹ at 13 TeV as 125.13 ± 0.15 GeV, and 125.06 ± 0.14 GeV when combined with 7+8 TeV diphoton data.
