Large Hadron Collider

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.

When two heavy ions collide inside a particle accelerator, they produce a near-perfect fluid through which an assortment of fundamental particles swim. For scientists to accurately simulate even a tiny drop of this hot and dense subatomic brew with a classical computer, it would take longer than the age of the universe. Scientists show how quantum computing could be a game-changer in our understanding of quantum processes.

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.
