Small, short-lived drops of early universe matter

What was matter like moments after the Big Bang? Particles emerging from the lowest energy collisions of small particles with large heavy nuclei at the Relativistic Heavy Ion Collider (RHIC) could hold the answer. Scientists ...

Within 10 years, a high-luminosity LHC at CERN

A new site opened on Friday, June 15, 2018, at the LHC, the Large Hadron Collider. Begun in 2011, this project aims to commission a high-luminosity LHC (HL-LHC) by 2026 that will increase the number of proton-proton collisions ...

Scientists studying nuclear spin make a surprising discovery

In proton-proton smashups, more neutrons scatter to the right than the left relative to the proton spin direction. That was the accepted wisdom, and scientists thought the pattern would hold even when the protons struck larger ...

Using the K computer, scientists predict exotic "di-Omega" particle

Based on complex simulations of quantum chromodynamics performed using the K computer, one of the most powerful computers in the world, the HAL QCD Collaboration, made up of scientists from the RIKEN Nishina Center for Accelerator-based ...

Collimators—the LHC's bodyguards

The performance of the LHC relies on accelerating and colliding beams made of tiny particles with unprecedented intensities. If even a small fraction of the circulating particles deviates from the precisely set trajectory, ...

Long-lived physics

New particles produced in the LHC's high-energy proton-proton collisions don't hang around for long. A Higgs boson exists for less than a thousandth of a billionth of a billionth of a second before decaying into lighter particles, ...

Surprising result shocks scientists studying spin

Imagine playing a game of billiards, putting a bit of counter-clockwise spin on the cue ball and watching it deflect to the right as it strikes its target ball. With luck, or skill, the target ball sinks into the corner pocket ...

Shocking results of galaxy-cluster collisions

A giant collision of several galaxy clusters, each containing hundreds of galaxies, has produced this spectacular panorama of shocks and energy. The collisions generated shock waves that set off a celestial fireworks display ...
