0 v 2 3 0 M ar 1 99 5 The Low Energy Effective Lagrangian for Photon Interactions in Any Dimension
نویسنده
چکیده
The subject of low energy photon-photon scattering is considered in arbitrary dimensional space-time and the interaction is widened to include scattering events involving an arbitrary number of photons. The effective interaction Lagrangian for these processes in QED has been determined in a manifestly invariant form. This generalisation resolves the structure of the weak-field Euler-Heisenberg Lagrangian and indicates that the component invariant functions have coefficients related, not only to the space-time dimension, but also to the coefficients of the Bernoulli polynomial.

We consider a description of membranes by (2+1)-dimensional field theory, or alternatively a description of irrotational, isentropic fluid motion by a field theory in any dimension. We show that these systems, as well as others related to them, admit a peculiar diffeomorphism symmetry, where the transformation rule for coordinates involves the fields. Consider the following field Lagrangian, de...

Besides their appearance at short distances > ∼ 1/M W , local dimension-eight operators also contribute to kaon matrix elements at long distances of order > ∼ 1/µ ope , where µ ope is the scale controlling the Operator Product Expansion in pure QCD, without weak interactions. This comes about in the matching condition between the effective quark Lagrangian and the Chiral Lagrangian of mesons. W...

We study the effective weak chiral Lagrangian within the framework of the instanton vacuum. We incorporate the ∆S = 1, 2 effective weak Hamiltonian into the effective low-energy QCD partition function defining the chiral symmetric quark-Goldstone boson interactions with the momentum-dependent dynamical quark mass. Employing the derivative expansion, we derive the corresponding weak effective La...

A complete characterization of all the possible effective interactions up to dimension 5 of the top and bottom quarks with the electroweak gauge bosons have been made within the context of the chiral Lagrangian. We show that the anomalous dimension 5 operators (19 in total) can contribute to the leading energy power (E 3 for fermion pairs with same sign helicities and E 2 for opposite sign heli...

The various dynamical scales below the pion mass involved in π + π − atoms are sequentially integrated out using non-relativistic effective field theory techniques. This allows us to systematically organise the corrections to the energy levels and decay width. We present our results in terms of a single unknown constant which may be obtained by matching to the Chiral Lagrangian with electromagn...
