Quantum Chromodynamics and Particle Interactions

Physicists refine the map of matter just after the Big Bang

A review of quantum chromodynamics surveys what scientists have learned about the phases of matter that existed about 10 microseconds after the Big Bang. It focuses on particle production, fluctuations and comparisons between collision data and theoretical predictions.

A new analysis could sharpen the search for a top-quark bound state

Researchers have proposed a way to reconstruct a possible bound state made of a top quark and its antimatter partner near the production threshold at the Large Hadron Collider. Preliminary results suggest the method could improve sensitivity by as much as 12 percent over the current strategy planned for the collider’s Run 3.
