Point Splitting and U(1) Gauge Invariance
Dirk Olivie
A gauge transformation in quantum electrodynamics involves the product of field operators at the same space-time point and hence does not have a well-defined meaning. One way to av…
Two-point functions of chiral operators in {\cal N}=4 SYM at order g^4
S. Penati, A. Santambrogio, D. Zanon
We compute two-point functions of chiral operators Tr Φ^3 in {\cal N}=4 SU(N) supersymmetric Yang-Mills theory to the order g^4 in perturbation theory. We perform explicit calculat…
Quantisation and Gauge Invariance
Jan Govaerts
Recent developments concerning canonical quantisation and gauge invariant quantum mechanical systems and quantum field theories are briefly discussed. On the one hand, it is shown…
An action for the (2,0) self-dual tensor multiplet in a conformal supergravity background
Kor Van Hoof
We present the action for a self-dual tensor in six dimensions, coupled to a (2,0) conformal supergravity background. This action gives rise to the expected equations of motion. An…
On the fundamental structure of nature and the unification of forces
J. Witters
A model for the fundamental structure of nature is presented. It is based on two fundamental fermions moving with the velocity of light and differing from each other by the project…
Magnetic fields, branes and noncommutative geometry
Daniela Bigatti, Leonard Susskind
We construct a simple physical model of a particle moving on the infinite noncommutative 2-plane. The model consists of a pair of opposite charges moving in a strong magnetic field…
corrections to the N=2 supersymmetric Born-Infeld action
A. De Giovanni, A. Santambrogio, D. Zanon
We consider the N=2 supersymmetric Born-Infeld action and compute one-loop divergences quantizing the theory in N=1 superspace. We find that in the presence of non constant curvatu…
Gravitino Production After Inflation
Renata Kallosh, Lev Kofman, Andrei Linde +1
We investigate the production of gravitinos in a cosmological background. Gravitinos can be produced during preheating after inflation due to a combined effect of interactions with…
Ramond-Ramond couplings of non-BPS D-branes
Marco Billo', Ben Craps, Frederik Roose
We study how non-BPS type II D-branes couple to R-R potentials. Upon tachyon condensation the couplings we find give rise to the Wess-Zumino action of BPS D-branes.
BRST Quantization of a Particle in AdS_5
Piet Claus, Renata Kallosh, J. Rahmfeld
We perform the quantization of a massive particle propagating on AdS_5. We use the twistor formulation in which the action can be brought into a quadratic form. We construct the BR…
A Simple Particle Action from a Twistor Parametrization of AdS_5
Piet Claus, J. Rahmfeld, Yonatan Zunger
The SO(4,2) isometries of AdS_5 are realized non-linearly on its horospherical coordinates (x^m,ρ). On the other hand, Penrose twistors have long been known to linearly realize the…
NS fivebranes in type 0 string theory
Ben Craps, Frederik Roose
The massless degrees of freedom of type 0 NS5-branes are derived. A non-chiral, purely bosonic spectrum is found in both type 0A and 0B. This non-chirality is confirmed by a one-lo…
The Gravitational Action in Asymptotically AdS and Flat Spacetimes
Per Kraus, Finn Larsen, Ruud Siebelink
The divergences of the gravitational action are analyzed for spacetimes that are asymptotically anti-de Sitter and asymptotically flat. The gravitational action is rendered finite…
Supertwistors as Quarks of SU(2,2|4)
Piet Claus, Murat Gunaydin, Renata Kallosh +2
The GS superstring on AdS_5 x S^5 has a nonlinearly realized, spontaneously broken SU(2,2|4) symmetry. Here we introduce a two-dimensional model in which the unbroken SU(2,2|4) sym…
Batalin-Vilkovisky gauge-fixing of a chiral two-form in six dimensions
Chris Van Den Broeck, Kor Van Hoof
We perform the gauge-fixing of the theory of a chiral two-form boson in six dimensions starting from the action given by Pasti, Sorokin and Tonin. We use the Batalin-Vilkovisky for…
(2,0) Tensor Multiplets and Conformal Supergravity in D=6
Eric Bergshoeff, Ergin Sezgin, Antoine Van Proeyen
We construct the supercurrent multiplet that contains the energy-momentum tensor of the (2,0) tensor multiplet. By coupling this multiplet of currents to the fields of conformal su…
A symplectic covariant formulation of special Kahler geometry in superconformal calculus
Piet Claus, Kor Van Hoof, Antoine Van Proeyen
We present a formulation of the coupling of vector multiplets to N=2 supergravity which is symplectic covariant (and thus is not based on a prepotential) and uses superconformal te…
On D-branes in Type 0 String Theory
Marco Billo', Ben Craps, Frederik Roose
Using boundary states we derive the presence of (chiral) fermions on the intersection of type 0 D-branes. The corresponding anomalous couplings on the branes are then computed. Fur…
The 0-brane action in a general D=4 supergravity background
Marco Billo, Sergio Cacciatori, Frederik Denef +3
We begin by presenting the superparticle action in the background of N=2, D=4 supergravity coupled to n vector multiplets interacting via an arbitrary special Kahler geometry. Our…
The D2-D6 System and a Fibered AdS Geometry
Oskar Pelc, Ruud Siebelink
The system of D2 branes localized on or near D6 branes is considered. The world-volume theory on the D2 branes is investigated, using its conjectured relation to the near-horizon g…
2D Yang-Mills Theory as a Matrix String Theory
M. Billo', M. Caselle, A. D'Adda +1
Quantization of two-dimensional Yang-Mills theory on a torus in the gauge where the field strength is diagonal leads to twisted sectors that are completely analogous to the ones th…
BPS solutions of a D5-brane worldvolume in a D3-brane background from superalgebras
Ben Craps, Joaquim Gomis, David Mateos +1
The BPS method is used to find BPS solutions of the worldvolume theory of a D5-brane in the near horizon geometry of a D3-brane. The BPS bound is interpreted in terms of the `maxim…
