Physicists discover new class of pentaquarks

Tomasz Skwarnicki, professor of physics in the College of Arts and Sciences at Syracuse University, has uncovered new information about a class of particles called pentaquarks. His findings could lead to a new understanding ...

Compelling evidence for small drops of perfect fluid

Nuclear physicists analyzing data from the PHENIX detector at the Relativistic Heavy Ion Collider (RHIC)—a U.S. Department of Energy (DOE) Office of Science user facility for nuclear physics research at Brookhaven National ...

Producing four top quarks at once to explore the unknown

For several decades, particle physicists have been trying to better understand nature at the smallest distances by colliding particles at the highest energies. While the Standard Model of particle physics has successfully ...

The state of the early universe: The beginning was fluid

Scientists from the Niels Bohr Institute, University of Copenhagen, and their colleagues from the international ALICE collaboration recently collided xenon nuclei in the superconducting Large Hadron Collider in order to gain ...

The early universe was a fluid quark-gluon plasma

Scientists from the Niels Bohr Institute, University of Copenhagen, and their colleagues from the international ALICE collaboration recently collided xenon nuclei, in order to gain new insights into the properties of the ...

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, ...
