ATLAS

The ATLAS experiment at CERN sees possible evidence of quark-gluon plasma production during collisions between photons and heavy nuclei inside the Large Hadron Collider.

From IRIS-HEP, April 10, 2021: Allison Hall, Fermilab LHC Physics Center researcher, is quoted in this story on the hardware upgrade to CERN’s Large LHC that will significantly boost the proton beams’ intensity.

Higgs-boson pairs could help scientists understand the stability of our universe. The trick is finding them.

From CERN, Jan. 26, 2021: This week marks the 50th anniversary of the first proton collisions in CERN’s Intersecting Storage Rings, the first hadron collider ever built. To celebrate, see hadron colliders of the last half-century — including the Tevatron and the Large Hadron Collider — through a historical lens, with an eye toward the quest for high luminosity and new energy frontiers.

The ATLAS collaboration has begun to publish likelihood functions, information that will allow researchers to better understand and use their experiment’s data in future analyses.

Once the most popular framework for physics beyond the Standard Model, supersymmetry is facing a reckoning — but many researchers are not giving up on it yet.

Scientists on an experiment at the Large Hadron Collider see massive W particles emerging from collisions with electromagnetic fields. How can this happen?

Scientists on experiments at the LHC are redesigning their methods and building supplemental detectors to look for new particles that might be evading them.

Scientists know the Higgs boson interacts with extremely massive particles. Now, they’re starting to study how it interacts with lighter particles as well.

Those who study particle physics will find that every step of the journey offers a new perspective and new set of responsibilities. Symmetry chats with scientists working at the Large Hadron Collider to hear about differences between seven different rungs on the academic career ladder.
