‘Inside the Box' Look at Excited Hadrons Could Help Solve Mystery of Particle X(3872)
Thomas Jefferson National Accelerator FacilitySo-called “XYZ states” defy the standard picture of particle behavior and have given rise to several attempts to understand their nature. But researchers with the Center for Theoretical and Computational Physics (Theory Center) at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility say there is a simpler way to explain the abundance of exotic charmonium particles using lattice quantum chromodynamics.
