beta function in a sentence
Examples
- In general, LAD are modelled with one-or two-parameters functions including ellipsoidal, rotated-ellipsoidal and Beta functions.
- Then for QCD, with N _ c = 3, the above equation reduces to that listed for the quantum chromodynamics beta function.
- In particular the renormalization group defines a flow on the space of coupling constants, with the beta function giving the corresponding vector field.
- where B is the beta function, \ alpha and \ beta are the shape parameters, and \ lambda is the noncentrality parameter.
- In non-Abelian gauge theories, the beta function can be negative, as first found by Frank Wilczek, David Politzer and David Gross.
- An example of this is the beta function for quantum chromodynamics ( QCD ), and as a result the QCD coupling decreases at high energies.
- Methods also exist for determining the flow coefficient as a function of the beta function \ beta and the location of the downstream pressure sensing tap.
- The Beta function ( in the denominator of the beta distribution ) approaches infinity, for both parameters approaching zero, ?, ? ?! 0.
- It is intimately connected with the polylogarithm, inverse tangent integral, polygamma function, Riemann zeta function, Dirichlet eta function, and Dirichlet beta function.
- Moreover, the perturbative beta function tells us that the coupling continues to increase, and QED becomes " strongly coupled " at high energy.
