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.

Scientists wrote over 1500 letters sharing what they hope the next decade of particle physics will bring. One motif: studying long-lived particles in a variety of ways — including an idea using a detector atop the CMS experiment at the Large Hadron Collider at CERN.

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.

Matter and antimatter particles can behave differently, but where these differences show up is still a puzzle. Scientists on the LHCb experiment at the Large Hadron Collider study much more subtle differences between matter particles and their antimatter equivalents. A recent analysis allowed them to revisit an old mystery — an asymmetry between asymmetries.

From the CMS collaboration, Nov. 30, 2020: On Nov. 24, the CMS collaboration at CERN’s Large Hadron Collider announced the publication of the 1,000th paper in a peer-review journal, an exceptional achievement for a single experiment. Fermilab scientist Boaz Klima, CMS Publications Committee chair, is quoted.

Results from the ProtoDUNE single-phase detector at CERN pave the way for detectors 20 times larger for the international Deep Underground Neutrino Experiment, hosted by Fermilab.

From CERN Courier, Sept. 23, 2020: Fermilab scientist Panagiotis Spentzouris, head of the Fermilab Quantum Science Program, is one of several experts featured in this article on CERN alumni who have ventured into diverse careers in different fields.

From CERN Courier, Sept. 9, 2020: The first ICHEP meeting since the publication of the update of the European strategy for particle physics covered Higgs and neutrino physics, including results from the CMS collider experiment and the DUNE, NOvA and MicroBooNE neutrino experiments.

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