Nonlinear realizations of symmetries and unphysical Goldstone bosons
I. N. McArthur
The embedding of a -brane into higher dimensional spacetime breaks not only translational symmetries transverse to the worldvolume, but also Lorentz symmetries. There exist form…
Effective action of beta-deformed N = 4 SYM theory: Farewell to two-loop BPS diagrams
Sergei M. Kuzenko, Ian N. McArthur
Within the background field approach, all two-loop sunset vacuum diagrams, which occur in the Coulomb branch of N = 2 superconformal theories(including N = 4 SYM), obey the BPS con…
The SU(N) Matrix Model at Two Loops
D. Grasso, I. N. McArthur
Multi-loop calculations of the effective action for the matrix model are important for carrying out tests of the conjectured relationship of the matrix model to the low energy desc…
Relaxed super self-duality and N = 4 SYM at two loops
S. M. Kuzenko, I. N. McArthur
A closed-form expression is obtained for a holomorphic sector of the two-loop low-energy effective action for the N = 4 super Yang-Mills theory on its Coulomb branch where the gaug…
Low-energy dynamics in N = 2 super QED: Two-loop approximation
S. M. Kuzenko, I. N. McArthur
The two-loop (Euler-Heisenberg-type) effective action for N = 2 supersymmetric QED is computed using the N = 1 superspace formulation. The effective action is expressed as a series…
On the Background Field Method Beyond One Loop: A manifestly covariant derivative expansion in super Yang-Mills theories
S. M. Kuzenko, I. N. McArthur
There are currently many string inspired conjectures about the structure of the low-energy effective action for super Yang-Mills theories which require explicit multi-loop calculat…
