Particle accelerator

Physicists at Brookhaven National Laboratory have discovered a completely new type of quantum entanglement, the spooky phenomenon that binds particles across any distance. This allowed scientists to peer inside nuclei in more detail than ever before.

This month marks the 10th anniversary of the discovery of the Higgs boson. But what exactly is this particle, and why is it so important? What has it taught us in the last decade – and more importantly, what could it teach us in the next decade?

The Large Hadron Collider (LHC), the largest and most powerful particle accelerator ever built, is ready to renter service after a three-year overhaul and refit. On April 22, two proton beams were sent around the the 27-kilometer-long ring.

A collaboration of physicists has made the most precise measurement of the mass of the W boson. The new measurement of this key particle differs drastically from the Standard Model's predictions– and it may unravel physics as we know it.

Fermilab physicists have developed a next-generation magnet that can generate a magnetic field with great efficiency, and used it to demonstrate what they describe as the world’s fastest ramping rates for particle accelerator magnets.

Physicists have detected “ghost particles” in the Large Hadron Collider for the first time. An experiment called FASER picked up signals of neutrinos being produced in particle collisions, which can help scientists better understand key physics.

A groundbreaking new imaging technique, utilizing X-rays 100 billion times brighter than a hospital X-ray machine, is offering 3D images in unprecedented detail, allowing whole organs to be imaged down to a resolution of 1 micron.

Physicists have outlined a relatively simple new way to create antimatter, by firing two lasers at each other to reproduce the conditions near a neutron star, converting light into matter and antimatter. Doing so could unlock cosmological mysteries.

A subatomic particle has been found switching between matter and antimatter, in Large Hadron Collider data. It turns out an unfathomably tiny weight difference between two particles could have saved the universe from annihilation soon after it began.

CERN’s Large Hadron Collider probes the fringes of known physics, and now the facility has found particles not behaving as predicted. While it’s early days, the discovery hints at the existence of new particles or forces beyond the Standard Model.

After a two-year shutdown for repairs and upgrades, CERN’s Large Hadron Collider is beginning to fire back up. The newest particle accelerator, Linac 4, completed its first test run over the past few weeks, and will produce much more powerful beams.

An extensive search for a hypothetical particle has turned up empty. The sterile neutrino is a proposed subatomic particle that could even be a candidate for the mysterious dark matter, but two new experiments have all but ruled it out.
