Out of the loop: CMS advances in the search for a rare Higgs boson decay
CMS pushes the sensitivity frontier towards a measurement of the rare Higgs boson decay into a Z boson and a photon The 2012 discovery of the Higgs boson at CERN by CMS and ATLAS was a landmark achievement in the world of particle physics – but it was only the beginning.

CMS weighs the Higgs boson using flashes of light
The CMS experiment reports a new measurement of the Higgs boson mass in the decay into two photons, improving the precision of this result over earlier measurements by refining detector calibration and new analysis techniques.
