2 and N = 4 Supergravity and the Liouville Theory in Superspace 1

چکیده

The two-dimensional (2d) manifestly locally supersymmetric actions describing the N=2 and N=4 extended super-Liouville theory coupled to the N=2 and N=4 conformal supergravity, respectively, are constructed in superspace. It is shown that the N=4 super-Liouville multiplet is described by the improved twisted-II scalar mul-tiplet TM-II, whose kinetic terms are given by the SU(2) ⊗ U(1) WZNW model.

A new N = 1 superfield model in D = 4 flat superspace is suggested. This model describes dynamics of chiral compensator and can be treated as a low-energy limit of D = 4, N = 1 quantum superfield supergravity. Renormalization structure of this model is studied and one-loop counterterms are calculated. It is shown that the theory is infrared free. An effective action for the model under consider...

N = 2 Super - Weyl Symmetry , Super - Liouville Theory and Super - Riemannian Surfaces

The finite form of the N = 2 super-Weyl transformations in the chiral and twistedchiral irreducible formulations of the two-dimensional N = 2 superfield supergravity are found in N = 2 superspace. The super-Weyl anomaly of the N = 2 extended fermionic string theory is computed in terms of the N = 2 superfields, by using a short time expansion of the N = 2 chiral heat kernel. The super-Weyl inva...

Superspace formulation of ten-dimensional N=1 supergravity coupled to N=1 super Yang-Mills theory.

We present an on-shell superspace formulation of ten-dimensional N = 1 supergravity coupled to N = 1 super Yang-Mills theory. The coupling is completely specified in superspace by the Bianchi dH = crtrF2, where H is the gauge-invariant S-form field strength of supergravity and F is the 2-form super Yang-Mills field strength. We also briefly discuss the theory that results from modifying this Bi...

R 4 terms and d = 4 supergravity

We start by a concise yet thorough revision of four-dimensional super-space supergravity. We present curved superspace geometry, for arbitrary N , including torsion, curvature and Bianchi identities. We motivate the choice of torsion constraints. We then consider the particular cases of N = 1, 2. In both cases we show how Poincaré supergravity can be obtained from conformal supergravity. We see...
