   Beta function
   [physics] This dependence on the energy scale is known as the running of the coupling parameter, and theory of this kind of scale-dependence in quantum field theory is described by the renormalization group. ==Scale invariance== If the beta functions of a quantum field theory vanish, usually...

   Beta function
   A measure of beam width. The beta function details how the beam changes around the accelerator. There are separate Beta functions for the x and y planes. The square root of bx is proportional to the beam's x-axis extent in phase space.

   Beta function
   The beta function was the first known scattering amplitude in string theory, first conjectured by Gabriele Veneziano. It also occurs in the theory of the preferential attachment process, a type of stochastic urn process. == Integrals == The Nörlund–Rice integral is a contour integral involving t...

   beta function
   The function B(m, n) = x^{m -1} (1 - x)^{n - 1} dx. It can be defined in terms of the gamma function by B(m, n) = G(m) G(n) ^____________ G(m + n) Many integrals can be reduced to the evaluation of b...
