CMS has sharpened its eyesight for highly collimated electron-positron pairs
The CMS collaboration has developed a new technique to distinguish electron-positron pairs travelling so closely together that we see them as a single cluster of deposited energy.

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.
