order of perturbation मीनिंग इन हिंदी

उदाहरण वाक्य

1. These conditions can only be satisfied perturbatively, but this has to hold at any order of perturbation theory.
2. Later uses include the extension of the proof of Goldstone's theorem to all orders of perturbation theory.
3. The number of Feynman diagrams at high orders of perturbation theory is very large, because there are as many diagrams as there are graphs with a given number of nodes.
4. Dyson could show that a rescaling of charge and mass ('renormalization') is sufficient to remove all divergences in QED consistently, to all orders of perturbation theory.
5. The implication of this for physics is that there are some phenomena which are impossible to understand by perturbation theory, regardless of how many orders of perturbation theory we use.
6. Using LSZ reduction formula we get from the " n "-point functions the corresponding process amplitudes, renormalizable and corrections are finite at any order of perturbation theory.
7. Gravity is itself a source of gravity, analogously to gauge theories ( whose couplings, are, by contrast, dimensionless ) leading to uncontrollable divergences at increasing orders of perturbation theory.
8. Elementary cross sections \ hat { \ sigma } are e . g . calculated to the leading order of perturbation theory in Peskin & Schroeder ( 1995 ), section 17.4.
9. The existence of such a fixed point is relevant, as it grants, at this order of perturbation theory, that conformal invariance is not lost due to quantum corrections, so that the quantum field theory of this model is sensible ( renormalizable ).
10. He also demonstrated that the 4d N = 4 supersymmetric gauge theory is power counting finite, proving that this theory is scale invariant to all orders of perturbation theory, the first example of a field theory where all the infinities in Feynman diagrams cancel.
