... 2nd example: magnetic moment of hyperons The neutral Λ0 lives τ = 0.26 ns. Its mass is mc2 = 1.1 GeV. When it is produced at Ekin = 400 GeV, its lifetime in the laboratory system is boosted to γτ = (Ekin /mc2)×0.26 ns ≈ 100 ns, and its mean flight length becomes cτ ≈ 30 m. The main decay mode is Λ0 ...

History of quantum field theory

In particle physics, the history of quantum field theory starts with its creation by Paul Dirac, when he attempted to quantize the electromagnetic field in the late 1920s. Major advances in the theory were made in the 1950s, and led to the introduction of quantum electrodynamics (QED). QED was so successful and ""natural"" that efforts were made to use the same basic concepts for the other forces of nature. These efforts were successful in the application of gauge theory to the strong nuclear force and weak nuclear force, producing the modern standard model of particle physics. Efforts to describe gravity using the same techniques have, to date, failed. The study of quantum field theory is alive and flourishing, as are applications of this method to many physical problems. It remains one of the most vital areas of theoretical physics today, providing a common language to many branches of physics.
