Comments on the complex linear Goldstino superfield
Sergei M. Kuzenko, Simon J. Tyler
It is shown that the complex linear Goldstino superfield recently proposed in arXiv:1507.01885 is obtained from the one originally constructed in arXiv:1102.3042 by a field redefin…
The one-loop effective potential of the Wess-Zumino model revisited
Sergei M Kuzenko, Simon J Tyler
The full one-loop supersymmetric effective potential for the Wess-Zumino model is calculated using superfield techniques. This includes the Kähler potential and the auxiliary field…
Studies of low-energy effective actions in supersymmetric field theories
Simon James Tyler
This thesis examines low-energy effective actions of supersymmetric quantum field theories. These actions contain information about the low-energy field content and dynamics of qua…
On the Goldstino actions and their symmetries
Sergei M. Kuzenko, Simon J. Tyler
Starting from the Akulov-Volkov (AV) action, we compute a finite-dimensional Lie group G of all field transformations of the form λ-> λ' = λ+ O(λ^3) which preserve the functional s…
Complex linear superfield as a model for Goldstino
Sergei M. Kuzenko, Simon J. Tyler
We propose a Goldstino model formulated in terms of a constrained complex linear superfield. Its comparison to other Goldstino models is given. Couplings to supersymmetric matter a…
Relating the Komargodski-Seiberg and Akulov-Volkov actions: Exact nonlinear field redefinition
Sergei M. Kuzenko, Simon J. Tyler
This paper constructs an exact field redefinition that maps the Akulov-Volkov action to that recently studied by Komargodski and Seiberg in arXiv:0907.2441. It is also shown that t…
Two loop Kahler potential in beta-deformed N=4 SYM theory
Simon J. Tyler
In N=2 superconformal field theories the Kahler potential is known to be tree level exact. The beta-deformation of N=4 SU(N) SYM reduces the amount of supersymmetry to N=1, allowin…
Supersymmetric Euler-Heisenberg effective action: Two-loop results
Sergei M. Kuzenko, Simon J. Tyler
The two-loop Euler-Heisenberg-type effective action for N = 1 supersymmetric QED is computed within the background field approach. The background vector multiplet is chosen to obey…
