Non-Large Hadron Collider Physics Program at CERN

CERN has a diversified program at the chain of accelerators also used as LHC injectors. Selected examples of recent results will be used to illustrate the depth and the breadth of the overall physics program. Starting from lowest energies – the only decelerator at CERN (AD) is looking at antimatter production and trapping. First trapped anti-hydrogen were reported in 2010. Interdisciplinary team is working in the CLOUD experiment, where systematic studies on condensation have just started with the unique equipment allowing control of contamination, temperature and radiation dose. They may affect our understanding of climate changes. At SPS, results from Compass on the studies of nucleon spin structure bring the conclusion on how much gluons contribute to the nucleon spin. These results will be presented in more details. SPS beam is also used to produce high energy neutrinos which are sent towards Gran Sasso underground laboratory where OPERA and ICARUS detectors are waiting to register them. First observation of tau neutrino interaction was reported by OPERA last year. It is expected that the broad and evolving physics program will be supported at CERN to complement the research at the energy frontier.
