Read article 'CMS measures the ‘underlying event’ in pp collisions'
Ever since the earliest experiments with hadron beams, and subsequently during the era of the hadron colliders heralded by CERN’s Intersecting Storage Rings, it has been clear that hadron collisions...
Read article 'LHCb observes two new strange-beauty baryons'
Predicted to exist by the quark model, they are both baryons containing three quarks, in this case, b, s and d.
Read article 'Profiling jets with ALICE'
Scaled pT spectra of charged particles in jets for different bins of jet transverse momentum. “Jets are collimated sprays of particles.” This ubiquitous characterization used in man...
Read article 'Two teams take big steps forward in plasma acceleration'
The high electric-field gradients that can be set up in plasma have offered the promise of compact particle accelerators since the late 1970s.
Read article 'Nuclei come under the microscope in California'
It has long been known that, when they are put under a sufficiently energetic microscope, nuclei reveal a complicated structure – the more energetic the probe, the more complex the structure.
Read article 'Gamma-ray bursts are a real threat to life'
A new study confirms the potential hazard of nearby gamma-ray bursts (GRBs), and quantifies the probability of an event on Earth and more generally in the Milky Way and other galaxies. The authors fin...

At its 173rd closed session on 4 November, CERN Council selected the Italian physicist Fabiola Gianotti as the organization’s next director-general.
Read article 'CUORE has the coldest heart in the known universe'
The CUORE collaboration at the INFN Gran Sasso National Laboratory has set a world record by cooling a copper vessel with the volume of a cubic metre to a temperature of 6 mK.
Read article 'NA62 gets going at the SPS'
With the end in sight for CERN’s Long Shutdown (LS1), the accelerator chain has been gradually restarting. Since early October, the Super Proton Synchrotron (SPS) has been delivering beams of proton...
