In an extraordinary feat of precision physics, CMS measures the mass of the W boson, and finds it to be in good agreement with the prediction by the Standard Model of particle physics. In the most precise measurement of its kind ever obtained at the…

  A primary goal of the Large Hadron Collider (LHC) is to hunt for evidence of beyond the Standard Model (BSM) dynamics through deviations from the Standard Model (SM) predictions. If the mass of BSM particles exceeds the energy accessible in LH…

  With the discovery of the Higgs boson in 2012, an important piece in our puzzle to understand the Universe was found. However, there are still many open questions: why is the Higgs boson so light? What is dark matter? How does gravity work at…
