  • 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 ...
  • Barak Kol (1999-11-01)
    5-brane configurations describing 5d field theories are promoted to an M-theory description la Witten in terms of polynomials in two complex variables. The coefficients of the polynomials are the Coulomb branch. This ...
  • 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 ...
  • Kazuo Hosomichi (1998-06-01)
    The absorption cross section of dilatinos by D3-branes is calculated by means of both classical type IIB supergravity and the effective gauge field theory on their worldvolume. The two methods give the same results, ...
  • 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 ...
  • Constantin P. Bachas; Michael B. Green (1998-01-01)
    The occupied and unoccupied fermionic BPS quantum states of a type-IIA string stretched between a D6-brane and an orthogonal D2-brane are described in M-theory by two particular holomorphic curves embedded in a ...
  • 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 ...
  • Raphael Bousso (1999-07-01)
    We conjecture the following entropy bound to be valid in all space-times admitted by Einstein's equation: let A be the area of any two-dimensional surface. Let L be a hypersurface generated by surface-orthogonal null ...
  • 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 ...
  • Gerardo Aldazabal; Luis E. Ibáñez; Fernando Quevedo (2000-02-01)
    The success of SU(5)-like gauge coupling unification boundary conditions g32 = g22 = 5/3g12 has biased most attempts to embed the SM interactions into a unified structure. After discussing the limitations ...
  • 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 ...
  • Andrew Strominger (1999-01-01)
    AdS2 has an SL(2,R) isometry group. It is argued that in the context of quantum gravity on AdS2 this group is enlarged to the full infinite-dimensional 1+1 conformal group. Massive scalar fields are coupled to AdS2 gravity ...
  • 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 ...
