LHC completes proton run for 2015, preps for lead

The Large Hadron Collider (LHC) has successfully completed its planned proton run for 2015, delivering the equivalent of about 400 trillion (1012) proton-proton collisions – some 4 inverse femtobarns of data – to both ...

Tiny drops of early universe 'perfect' fluid

The Relativistic Heavy Ion Collider (RHIC), a particle collider for nuclear physics research at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, smashes large nuclei together at close to the speed of ...

Accelerating argon

Over the past few days, the SPS has been accelerating argon ions, which have started to be sent to the NA61/SHINE experiment. This operating mode, using a new type of ion, required a number of modifications to the accelerator.

Infographic: Rhic cooks up a quantum tempest in a teacup

When particles collide inside Brookhaven Lab's Relativistic Heavy Ion Collider (RHIC), they melt at trillion-degree temperatures and form a friction-free "perfect" liquid. This quark-gluon plasma, composed of the liberated ...
