![]() | DeTar, Carleton | Lattice quantum chromodynamics comes of age | The strength of the electron-photon interaction is characterized by the fine-structure constant α ≈ 1/137.036. Because α is small, quantum electrodynamics (QED), the theory of interacting electrons and photons, can be solved to very good approximation with the traditional technology of pencil an... | Quarks; Gluons; Mesons; CKM matrix | 2004 |
