Action for IIB Supergravity in 10 dimensions
G. Dall'Agata, K. Lechner, M. Tonin
We review the construction of a manifestly covariant, supersymmetric and SL(2R) invariant action for IIB supergravity in D=10.
Gauge-invariant charged, monopole and dyon fields in gauge theories
J. Froehlich, P. A. Marchetti
We propose explicit recipes to construct the euclidean Green functions of gauge-invariant charged, monopole and dyon fields in four-dimensional gauge theories whose phase diagram c…
The instanton contributions to Yang-Mills theory on the torus: localization, Wilson loops and the perturbative expansion
L. Griguolo
The instanton contributions to the partition function and to homologically trivial Wilson loops for a U(N) Yang-Mills theory on a torus are analyzed. An exact expression for…
Self-dual tensors and gravitational anomalies in 4n+2 dimensions
Kurt Lechner
Starting from a manifestly Lorentz- and diffeomorphism-invariant classical action we perform a perturbative derivation of the gravitational anomalies for chiral bosons in 4n+2 dime…
On gauge-fixed superbrane actions in AdS superbackgrounds
Paolo Pasti, Dmitri Sorokin, Mario Tonin
To construct actions for describing superbranes propagating in AdS x S superbackgrounds we propose a coset space realization of these superbackgrounds which results in a short poly…
Equivalence Principle: Tunnelling, Quantized Spectra and Trajectories from the Quantum HJ Equation
Alon E. Faraggi, Marco Matone
A basic aspect of the recently proposed approach to quantum mechanics is that no use of any axiomatic interpretation of the wave function is made. In particular, the quantum potent…
Equivalence Principle, Planck Length and Quantum Hamilton-Jacobi Equation
Alon E. Faraggi, Marco Matone
The Quantum Stationary HJ Equation (QSHJE) that we derived from the equivalence principle, gives rise to initial conditions which cannot be seen in the Schroedinger equation. Exist…
Intersecting Branes and Anti-de Sitter Spacetimes in Gauged Supergravity
Harvendra Singh
In this note we extend our work in a previous paper hep-th/9801038. We show here that various intersecting brane-like configurations can be found in the vacuum of superg…
Harmonics, Notophs and Chiral Bosons
Paolo Pasti, Dmitri Sorokin, Mario Tonin
A way of covariantizing duality symmetric actions is described.
Time exponentiation of a Wilson loop for Yang-Mills theories in 2+εdimensions
A. Bassetto, R. Begliuomini, G. Nardelli
A rectangular Wilson loop centered at the origin, with sides parallel to space and time directions and length and respectively, is perturbatively evaluated ${\cal O}(g^4)…
Two-dimensional QCD, instanton contributions and the perturbative Wu-Mandelstam-Leibbrandt prescription
A. Bassetto, L. Griguolo
The exact Wilson loop expression for the pure Yang-Mills U(N) theory on a sphere of radius exhibits, in the decompactification limit , the expected pure area…
D=10, N=IIB Supergravity: Lorentz-invariant actions and duality
Gianguido Dall'Agata, Kurt Lechner, Mario Tonin
We present a manifestly Lorentz invariant and supersymmetric component field action for , type supergravity, using a newly developed method for the construction of ac…
Duality of Self-Dual Actions
Alexey Maznytsia, Christian Preitschopf, Dmitri Sorokin
Using examples of a D=2 chiral scalar and a duality-symmetric formulation of D=4 Maxwell theory we study duality properties of actions for describing chiral bosons. In particular,…
Effective interactions of a light gravitino
Fabio Zwirner
We review some recent results on the effective interactions of a light gravitino with ordinary particles. In particular, we discuss on a simple example a novel aspect of the low-en…
Beta Function, C--Theorem and WDVV Equations in 4D N=2 SYM
G. Bertoldi, M. Matone
We show that the exact --function of 4D N=2 SYM plays the role of the metric whose inverse satisfies the WDVV--like equations $\F_{ikl}β^{lm} \F_{mnj}=\F_{jkl}β^{lm}\F_{mni}$…
New Supersymmetric Vacua for N=4, D=4 Gauged Supergravity
Harvendra Singh
In this paper we obtain supersymmetric brane-like configurations in the vacuum of N=4 gauged supergravity theory in four spacetime dimensions. Almost all of the…
Quantum Transformations
Alon E. Faraggi, Marco Matone
We show that the stationary quantum Hamilton-Jacobi equation of non-relativistic 1D systems, underlying Bohmian mechanics, takes the classical form with replaced by $\…
