LEPP

Cornell's Laboratory for Elementary-Particle Physics studies nature's fundamental particles and the laws that govern them. These studies shed light on questions like: how did the universe evolve? What is the nature of space and time? What, really, is mass?

LEPP physicists also develop the technology behind accelerators, which are our central window onto nature at its tiniest and are a vital tool for other sciences that explore nature at the scale of atoms and molecules.

LEPP communicates widely about its research in order to deepen public understanding of the physical sciences, improve scientific literacy, and share the excitement of discovery.

LEPP, the Cornell University Laboratory for Elementary-Particle Physics, and CHESS resources have merged and a new lab, (CLASSE), has formed. CLASSE develops and operates facilities and provides infrastructure for the study of beams and accelerators, photon science, particle physics and the early universe, serving students, the public and scientists from Cornell and elsewhere. LEPP's primary source of support is the National Science Foundation.
