Read article 'Run 2 promises a harvest of beauty for LHCb'
The first b-physics analysis using data from LHC Run 2, which began in 2015 with proton–proton collisions at an energy of 13 TeV, shows great promise for the physics programme of LHCb. During 201...
Read article 'ALICE zeroes in on cold-matter effects'
Measuring the production cross-section of charm hadrons in proton–proton collisions provides an important test of perturbative quantum chromodynamics (QCD). In proton–nucleus collisions, “cold-m...
Read article 'Protons probe quark–gluon plasma at CMS'
Proton–nucleus collisions provide a crucial tool to investigate the quark–gluon plasma (QGP), a state of nuclear matter with a high energy density spread over a relatively large volume. Although p...
Read article 'Electron gun shrunk to matchbox size'
A team of researchers from DESY and MIT has built a new kind of electron gun that is about the size of a matchbox.
Read article 'Compact star hints at vacuum polarisation'
Astronomers may have found the first observational indication of a strange quantum effect called vacuum birefringence.
Read article 'Ukraine becomes associate Member State of CERN'
Ukraine has been a long-time contributor to the ALICE, CMS and LHCb experiments at the LHC and to R&D in accelerator technology.
Read article 'CLOUD experiment sharpens climate predictions'
Future global climate projections have been put on more solid empirical ground, thanks to new measurements of the production rates of atmospheric aerosol particles by CERN’s Cosmics Leaving OUtdoor ...
Read article 'n_TOF deepens search for missing cosmic lithium'
CERN’s neutron time-of-flight (n_TOF) facility has filled in a missing piece of the cosmological-lithium problem puzzle.
Read article 'ATLAS spots light-by-light scattering'
Heisenberg and his student Euler realised that photons may scatter off of each other through a quantum-loop process involving virtual electron and positron pairs.
Read article 'Studies of electroweak-boson production by CMS'
It is quite improbable for two colliding protons to produce a W or Z electroweak gauge boson. Producing two or more W or Z bosons in the same collision is even less likely.
