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 n…

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 vect…

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. The event took place on the 15th of M…
