    From pieces to precision: building the Higgs boson’s clearest portrait to date

    In a much anticipated result, the CMS experiment presents the legacy combination of Higgs boson studies using the full LHC Run 2 data, recorded between 2016 and 2018 – the result is the most precise and comprehensive measurement of the Higgs boson by CMS to date.

    Broken mirrors: Do top quarks and Z bosons defy charge-inversion and reflection symmetry?

    For the first time, the CMS experiment has employed physics-informed machine learning to observe whether the laws of physics still hold true when top quarks and Z bosons are replaced with their antiparticles and space is reflected.
