First observation of photons-to-taus in proton–proton collisions by CMSPress releasexeno Mon, 03/25/2024 - 11:04924 Using the outstanding tracking capabilities of the CMS detector, the collaboration observed two photons producing two tau-leptons in proton–proton collisions In March 2024, the CMS collaboration announced the observation of two photons creating two tau leptons in proton–proton collisions. It is the first time that this process has been seen in proton–proton collisions, which was made possible by using the precise tracking capabilities of the CMS detector. It is also the most prec ..read more

Super Strong Magnetic Fields Leave Imprint on Nuclear MatterPress ReleaseLauren Fri, 02/23/2024 - 09:38824 Data from heavy ion collisions give new insight into electromagnetic properties of quark-gluon plasma Collisions of heavy ions generate an immensely strong electromagnetic field. Scientists investigate traces of this powerful electromagnetic field in the quark-gluon plasma (QGP), a state where quarks and gluons are liberated from the colliding protons and neutrons.
