  • Beyond the script: Does the Higgs boson improvise in its interactions?

    Beyond the script: Does the Higgs boson improvise in its interactions?

    By observing decays of Higgs bosons into pairs of photons, the CMS experiment probes anomalous interactions, including those between Higgs bosons and W/Z bosons or gluons when all particles are replaced with their antiparticles and space is reflected.
