Gauge Theories in the Derivative Expansion
نویسنده
چکیده
Gauge theories with and without matter are formulated in the derivative expansion. Amplitudes are derived as a power series in the energy scales; there are simplifications as compared with the usual loop expansion. The incorporation and summation of Wilson loops is natural in this approach and allows for a derivation of the confining potential as well as the masses of the gauge invariant observables.

N = 4 Supersymmetric Gauge Theory in the Derivative Expansion
Maximally supersymmetric gauge theories have experienced renewed interest due to the AdS/CFT correspondence and its conjectured S-duality. These gauge theories possess a large amount of symmetry and have quasi-integrable properties. We derive the amplitudes in the derivative expansion of the spontaneously broken examples and perform all loop integrations. The S-matrix is found via an algebraic ...
متن کاملInstantons, Higher-Derivative Terms, and Nonrenormalization Theorems in Supersymmetric Gauge Theories
We discuss the contribution of ADHM multi-instantons to the higher-derivative terms in the gradient expansion along the Coulomb branch of N = 2 and N = 4 supersymmetric SU(2) gauge theories. In particular, using simple scaling arguments, we confirm the DineSeiberg nonperturbative nonrenormalization theorems for the 4-derivative/8-fermion term in the two finite theories (N = 4, and N = 2 with NF...

We investigate the convergence of the derivative expansion of the exact renormali-sation group, by using it to compute the β function of scalar λϕ 4 theory. We show that the derivative expansion of the Polchinski flow equation converges at one loop for certain fast falling smooth cutoffs. The derivative expansion of the Legendre flow equation trivially converges at one loop, but also at two loo...
متن کاملGauge independence of the bubble nucleation rate in theories with radiative symmetry breaking.
In field theories where a metastable false vacuum state arises as a result of radiative corrections, the calculation of the rate of false vacuum decay by bubble nucleation depends on the effective potential and the other functions that appear in the derivative expansion of the effective action. Beginning with the Nielsen identity, we derive a series of identities that govern the gauge dependenc...

Higher Derivative (HD) Field Theories can be transformed into second order equivalent theories with a direct particle interpretation. In a simple model involving abelian gauge symmetries we examine the fate of the possible gauge fixings throughout this process. This example is a useful test bed for HD theories of gravity and provides a nice intuitive interpretation of the " third ghost " occurr...
