Effective action of softly broken supersymmetric theories [PDF]
We study the renormalization of (softly) broken supersymmetric theories at the one loop level in detail. We perform this analysis in a superspace approach in which the supersymmetry breaking interactions are parameterized using spurion insertions. We comment on the uniqueness of this parameterization.

Construction of the effective action in nonanticommutative supersymmetric field theories [PDF]
We develop a general gauge invariant construction of the one-loop effective action for supersymmetric gauge field theories formulated in ${\cal N}=1/2$ superspace. Using manifestly covariant techniques (the background superfield method and proper-time representations) adopted to the ${\cal N}=1/2$ superspace we show how to define unambiguously the ...

One-loop effective potential in nonlocal supersymmetric theories [PDF]
Within the superfield approach, we consider the nonlocal generalization of the Wess-Zumino model and calculate the one-loop low-energy contributions to the effective action. Four different nonlocal models are considered, among which only the first model does not reduce to the standard Wess-Zumino model when we take the parameter of nonlocality of the ...

The effective lagrangian of supersymmetric Yang-Mills theory [PDF]
Abstract The one-loop effective action of the supersymmetric Yang-Mills theory in the presence of a covariantly constant Yang-Mills superfield is calculated. This is done with the help of Schwinger's proper time method. The propagator of the Yang-Mills superfield in the presence of a non-vanishing background superfield is derived in a closed form ...

The Supersymmetric Effective Field Theory of Inflation [PDF]
We construct the Supersymmetric Effective Field Theory of Inflation, that is the most general theory of inflationary fluctuations when time-translations and supersymmetry are spontaneously broken. The non-linear realization of these invariances allows us to define a complete SUGRA multiplet containing the graviton, the gravitino, the Goldstone of time ...

ON THE DETERMINATION OF EFFECTIVE POTENTIALS IN SUPERSYMMETRIC THEORIES [PDF]
Abstract We propose a renormalization procedure for dynamically generated effective actions. We show that, as expected, it leads to no spontaneous supersymmetry breaking if this is unbroken at the tree level. We also understand why the usually adopted renormalization prescription has led in some models to an apparent supersymmetry breaking for an ...
