The CMS collaboration expands the search for supersymmetry by exploring a wide variety of final states with boosted particles, in a new analysis called “razor boost”. Supersymmetry, or SUSY, which suggests that every known particle has a new…
CMS breaks new ground by reconstructing challenging photon signatures using machine learning, opening new paths in the search for physics beyond the standard model. What if a new exotic particle from a non-standard Higgs boson decay escaped…
  Remember the media buzz when we finally pinned down the Higgs boson in 2012? Turns out it might have a shadowy cousin – the dark Higgs – and CMS is chasing it down. CMS scoured its entire Run 2 data set,138 fb–1 of proton-proton collisions at…
  For the first time, the CMS experiment measures the production of single top quarks in a mode called the “t-channel” at 5.02 TeV, reporting results aligned with the standard model expectations. In the quest to probe the fundamental laws of…
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. Identifying electrons is one of the greatest strengths of the CMS…
  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…
The CMS experiment sets limits for BSM particles down to tens-of-MeV aided by machine learning techniques. Axion-like particles (ALPs) are hypothetical light-weight neutral bosons that could solve deep mysteries in physics, from the strong CP…
The CMS experiment employs a new machine-learning algorithm to improve the reconstruction of invisible particles. How can one measure particles that escape the detector without interaction? This is the challenge for a key fundamental particle, the…
For the first time ever, the excited states of three beauty mesons are fully reconstructed and their masses are measured directly, using data from the CMS experiment. The existence of the excited B meson states, B*+, B*0, and B*0s(also known as…
The CMS Collaboration hunts for Higgs bosons recoiling against dark matter particles Dark matter is one of the most perplexing mysteries of our universe, accounting for roughly 27% of its total energy. Dark matter does not emit, absorb, or reflect…
  The CMS experiment achieves the most precise determination of the strength of the strong nuclear force using the rates of production of jets at several centre-of-mass energies. The strengths of the fundamental interactions in Nature drive the…
  By studying events with only a single energetic photon, the CMS experiment places some of the most stringent constraints to date on dark matter models and theories predicting extra dimensions of space. One way to explore physics beyond the…
