(19990901)We give an explicit expression for classical 1/4BPS fields in supersymmetric YangMills theory on noncommutative tori. We use it to study quantum 1/4BPS states. In particular we calculate the degeneracy of 1/4BPS energy ...

(20001101)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. ...

(20001101)The typeIIB supergravity solution describing a collection of regular and fractional D3branes on the conifold (hepth/0002159) was recently generalized to the case of the deformed conifold (hepth/0007191). Here we present ...

(20000501)We compute all 3point 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 ...

(19991101)5brane configurations describing 5d field theories are promoted to an Mtheory description la Witten in terms of polynomials in two complex variables. The coefficients of the polynomials are the Coulomb branch. This ...

(19980101)The lowenergy supersymmetric quantum mechanics describing Dparticles in the background of D8branes and orientifold planes is analyzed in detail, including a careful discussion of Gauss' law and normal ordering of ...

(19990901)A 3d topological sigma model describing maps from a 3manifold Y to a CalabiYau 3fold M is introduced. As the model is topological, we can choose an arbitrary metric on M. Upon scaling up the metric, the path integral ...

(19990801)We study the coupling of abelian gauge theories to fourdimensional 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 ...

(20000501)We calculate the classical crosssection for absorption of a minimally coupled scalar in the doublecentered D3brane geometry. The dual field theory has gauge symmetry broken to S(U(N1) U(N2)) and is on the Coulomb branch ...

(19980601)The absorption cross section of dilatinos by D3branes 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, ...

(19980701)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 ...

(19980101)The occupied and unoccupied fermionic BPS quantum states of a typeIIA string stretched between a D6brane and an orthogonal D2brane are described in Mtheory by two particular holomorphic curves embedded in a ...

(19991001)We propose a simple model for studying smallx physics in which we take only the collinearly enhanced part of leading and subleading kernels, for all possible transverse momentum orderings. The smallx equation reduces to ...

(19990701)We conjecture the following entropy bound to be valid in all spacetimes admitted by Einstein's equation: let A be the area of any twodimensional surface. Let L be a hypersurface generated by surfaceorthogonal null ...

(20000901)We consider `brane universe' scenarios with standardmodel fields localized on a 3brane in 6 spacetime dimensions. We show that if the spacetime is rotationally symmetric about the brane, local quantities in the bulk are ...

(20001001)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, GibbonsHawking approach and CFT through ...

(20000201)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 ...

(20001101)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 ...

(19990101)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 infinitedimensional 1+1 conformal group. Massive scalar fields are coupled to AdS2 gravity ...

(19981201)The duality relating nearhorizon 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 ...
