The OPERA experiment, located at the Gran Sasso Laboratory of the Italian National Institute for Nuclear Physics (INFN), was designed to conclusively prove that muon-neutrinos can convert to tau-neutrinos, through a process called neutrino oscillation, whose discovery was awarded the 2015 Nobel Physics Prize.
In this section you will find CERN's latest updates and press releases.
The ALPHA collaboration has reported the most precise direct measurement of antimatter ever made, revealing the spectral structure of the antihydrogen atom in unprecedented colour. The result, published today in Nature, is the culmination of three decades of research and development at CERN, and opens a completely new era of high-precision tests between matter and antimatter.
Cameras at the ready! On 1st June 2018, 20 photographers will be given an exclusive opportunity to explore the world’s largest particle physics laboratory. CERN is teaming up with major science laboratories for an international photography competition: the Global Physics Photowalk.
Arts at CERN pioneers new ways of bringing together artists and scientists, leads the conversation about art and science, and supports artistic creativity and curiosity towards fundamental research. Artists from all over the world are invited, through our cultural programmes, to spend time at CERN and work alongside particle physicists and engineers.
Geneva 12 February 2018. In a paper published today in the European Physical Journal C, the ATLAS Collaboration reports the first high-precision measurement at the Large Hadron Collider (LHC) of the mass of the W boson. This is one of two elementary particles that mediate the weak interaction – one of the forces that govern the behaviour of matter in our universe. The reported result gives a value of 80370±19 MeV for the W mass, which is consistent with the expectation from the Standard Model of Particle Physics, the theory that describes known particles and their interactions.
