At the end of November, European funding agencies for astroparticle physics launched a new sustainable entity, the Astroparticle Physics European Consortium.
Read article 'ATLAS enlists monojets in search for new physics'
Events with a single jet of particles in the final state have traditionally been studied in the context of searches for supersymmetry, for large extra spatial dimensions and for candidates for dark ma...
Read article 'Bs → μμ seen after being sought for decades'
It has taken decades of hunting but finally the first evidence for one of the rarest particle decays ever seen in nature, the decay of a Bs (composed of a beauty antiquark and a strange quark) into tw...
Read article 'Mysterious long-range correlations seen in pPb collisions'
The CMS collaboration has published its first result on proton–lead (pPb) collisions, related to the observation of a phenomenon that was seen first in nucleus–nucleus collisions but also detected...
Read article 'New boson’s mirror image looks like the Higgs'
More than 20 years ago, the CMS and ATLAS experiments at the LHC embarked on a long road into the unknown and, rather like Christopher Columbus, the two collaborations reached a new land last summer....
Read article 'Terbium: a new ‘Swiss army knife’ for nuclear medicine'
A team of scientists from the Paul Scherrer Institute (PSI), CERN’s ISOLDE facility and the Institut Laue-Langevin (ILL) has published results from a preclinical study of new tumour-targeting radiop...
Read article 'Hubble reveals earliest galaxies'
Although the Hubble Space Telescope is more than 22 years old, the regular upgrade of its instruments preserves intact its discovery potential as time goes by. Now, its quest to detect the most d...
