  • Anatoly Konechny; Albert Schwarz (1999-09-01)
    We give an explicit expression for classical 1/4-BPS fields in supersymmetric Yang-Mills theory on noncommutative tori. We use it to study quantum 1/4-BPS states. In particular we calculate the degeneracy of 1/4-BPS energy ...
  • Alistair Hart; Biagio Lucini; Mike Teper; Zsolt Schram (2000-11-01)
    We calculate the euclidean action of a pair of 2 monopoles (instantons), as a function of their spatial separation, in D = 21 SU(2) lattice gauge theory. We do so both above and below the deconfining transition at T = Tc. ...
  • Leopoldo A. Pando Zayas; Arkady A. Tseytlin (2000-11-01)
    The type-IIB supergravity solution describing a collection of regular and fractional D3-branes on the conifold (hep-th/0002159) was recently generalized to the case of the deformed conifold (hep-th/0007191). Here we present ...
  • Fiorenzo Bastianelli; Roberto Zucchini (2000-05-01)
    We compute all 3-point functions of the ``universal'' scalar operators contained in the interacting, maximally supersymmetric CFTs at large N by using the AdS/CFT correspondence. These SCFTs are related to the low energy ...
  • Constantin P. Bachas; Michael B. Green; Adam Schwimmer (1998-01-01)
    The low-energy supersymmetric quantum mechanics describing D-particles in the background of D8-branes and orientifold planes is analyzed in detail, including a careful discussion of Gauss' law and normal ordering of ...
  • Ali Imaanpur (1999-09-01)
    A 3d topological sigma model describing maps from a 3-manifold Y to a Calabi-Yau 3-fold M is introduced. As the model is topological, we can choose an arbitrary metric on M. Upon scaling up the metric, the path integral ...
  • Jan Ambjørn; Konstantinos N. Anagnostopoulos; Jerzy Jurkiewicz (1999-08-01)
    We study the coupling of abelian gauge theories to four-dimensional simplicial quantum gravity. The gauge fields live on dual links. This is the correct formulation if we want to compare the effect of gauge fields on ...
  • Miguel S. Costa (2000-05-01)
    We calculate the classical cross-section for absorption of a minimally coupled scalar in the double-centered D3-brane geometry. The dual field theory has gauge symmetry broken to S(U(N1) U(N2)) and is on the Coulomb branch ...
  • Luis E. Ibáñez (1998-07-01)
    Supersymmetric N = 1, D = 4 string vacua are known to be finite in perturbation theory. However, the effective low energy D = 4, N = 1 field theory lagrangian does not yield, in general, finite theories. In this note ...
  • Marcello Ciafaloni; Dimitri Colferai; Gavin P. Salam (1999-10-01)
    We propose a simple model for studying small-x physics in which we take only the collinearly enhanced part of leading and subleading kernels, for all possible transverse momentum orderings. The small-x equation reduces to ...
  • Jiunn-Wei Chen; Markus A. Luty; Eduardo Pontón (2000-09-01)
    We consider `brane universe' scenarios with standard-model fields localized on a 3-brane in 6 spacetime dimensions. We show that if the spacetime is rotationally symmetric about the brane, local quantities in the bulk are ...
  • Marco Caldarelli; Luciano Vanzo; Gianluigi Catelani (2000-10-01)
    The boundary terms in the hamiltonian, in the presence of horizons, are carefully analyzed in a simple 2D theory admitting AdS black holes. The agreement between the euclidean, Gibbons-Hawking approach and CFT through ...
  • Noriaki Ikeda (2000-11-01)
    We consider a deformation of three dimensional BF theory by means of the antifield BRST formalism. Possible deformations for the action and the gauge symmetries are analyzed. We find a new class of gauge theories which ...
  • Juan Maldacena; Andrew Strominger (1998-12-01)
    The duality relating near-horizon microstates of black holes obtained as orbifolds of a subset of AdS3 to the states of a conformal field theory is analyzed in detail. The SL(2,R)LSL(2,R)R invariant vacuum on AdS3 ...
  • Jacek Pawelczyk; Stefan Theisen (1998-09-01)
    We compute (3) corrections to the AdS5S5 black hole metric. We find that the radius of the S5 depends on the radial AdS5 coordinate. This completes the computation of Gubser, Klebanov and Tseytlin (hep-th/9805156). The ...
  • Edward Witten (1998-12-01)
    In = 4 super Yang-Mills theory on a four-manifold M, one can specify a discrete magnetic flux valued in H2(M,N). This flux is encoded in the AdS/CFT correspondence in terms of a five-dimensional topological field theory ...
  • Roberto Emparan (1999-06-01)
    The horizon of a static black hole in anti-de Sitter space can be spherical, planar, or hyperbolic. The microscopic dynamics of the first two classes of black holes have been extensively discussed recently within the ...
  • Esperanza Lopez (1999-02-01)
    We obtain = 1 SU(N)k gauge theories with bifundamental matter and a quartic superpotential as the low energy theory on D3-branes at singular points. These theories generalize that on D3-branes at a conifold point, ...
  • Igor Pesando (1998-11-01)
    We describe the type IIB supergravity background on AdS5S5 using the potentials of AdS5|4S5 and we use the supersolvable algebra associated to AdS5|4 to compute the gauge fixed type IIB string action.
  • Tim R. Morris (2000-12-01)
    A manifestly gauge invariant and regularized renormalization group flow equation is constructed for pure SU(N) gauge theory in the large-N limit. In this way we make precise and concrete the notion of a non-perturbative ...
