### LHCb discovers new baryon

The LHCb collaboration has discovered a new weakly decaying particle: a baryon called the Ξ++cc, which contains two charm quarks and an up quark. The discovery of the new particle, which was observed...

### FAIR forges its future

Supernova explosions, neutron-star mergers and rare radioactive ions might not seem to have much connection to terrestrial matters. Yet, while the lightest elements were synthesised immediately after ...

### Proton–proton collisions become stranger

Recreating the intense fireball of quarks and gluons that existed immediately after the Big Bang, the quark–gluon plasma (QGP), traditionally requires high-energy collisions between heavy ions such ...

### LHCb brings cosmic collisions down to Earth

The LHCb collaboration has generated high-energy collisions between protons and helium nuclei similar to those that take place when cosmic rays strike the interstellar medium.

### ALICE reveals dominance of collective flow

The study of the anisotropic flow in heavy-ion collisions at the LHC, which measures the momentum anisotropy of the final-state particles, has been effective in characterising the extreme states of ma...

### ATLAS reveals more strangeness in the proton

The excellent theoretical understanding of the production of electroweak W and Z gauge bosons in proton–proton collisions at the LHC makes these “standard-candle” processes ideal for studying th...
