Read article 'First measurements of electroweak boson fusion'
In proton collisions at the LHC, vector boson fusion (VBF) happens when quarks from each one of the two colliding protons radiate W or Z bosons that subsequently interact or "fuse" as in the Feynman d...
Read article 'LHCb pins down X(3872) quantum numbers'
One of the most interesting discoveries of the past decade is that of an unconventional hadron, the X(3872), by the Belle experiment (Belle 2003).

Despite first being described over three centuries ago, gravity remains one of the least understood of the fundamental forces.
Read article 'Pulsar exhibits puzzling switches in state'
Astronomers have detected simultaneous X-ray and radio-mode switches in co-ordinated observations of a pulsar. Pulsed X-ray emission is only present in states of weak radio emission. This indicates a ...
Read article 'Marking the end of the first proton run'
At 6 a.m. on 17 December, operators ended the LHC’s first three-year-long run for proton physics with a new performance milestone. In the preceding days, the space between proton bunches had been ...
Read article 'CERN becomes UN observer'
On 14 December, the UN General Assembly adopted a resolution to allow CERN to participate in the work of the General Assembly and to attend its sessions as an observer.
Read article 'BOSS gives clearer view of baryon oscillations'
In November the Baryon Oscillation Spectroscopic Survey (BOSS) released its second major result of 2012, using 48,000 quasars with redshifts (z) up to 3.5 as backlights to map intergalactic hydrogen ...
Read article 'Europe launches consortium for astroparticle physics'
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...
