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.
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.
This year, the LHC is colliding more than protons and lead ions: oxygen and neon have also made it into the collider, and are being studied by CMS and the other LHC experiments in order to understand the early universe!
The CMS experiment sets limits for BSM particles down to tens-of-MeV aided by machine learning techniques.
On the 9th of June, CMS took part in the annual ‘Colour Run’ in Cessy, France. This is a local event organised by the Cessy town hall for the people of Cessy and Pays du Gex, and features a 5km fun run with powdered paint being thrown at 1km intervals by eager spectators!
The CMS Collaboration is pleased to announce the recipients of the 2024 CMS Awards, recognizing individuals who have made significant contributions across the experiment.
The CMS experiment employs a new machine-learning algorithm to improve the reconstruction of invisible particles.
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.
CMS has officially inaugurated its new control room in Cessy, France. Guests from CERN management and all the LHC experiments were invited to celebrate this significant upgrade to CMS’ operational infrastructure.
