TL;DR: In this paper, it was shown that the ten-dimensional E 8 × E 8 heterotic string is related to an eleven-dimensional theory on the orbifold R 10 × S 1 / Z 2.

TL;DR: In this paper, the authors constructed compact examples of D-manifolds for type IIB strings and showed that the construction has a natural interpretation in terms of compactification of a 12-dimensional ''F-theory''.

TL;DR: In this paper, it was shown that the Type IIB superstring in ten dimensions has a family of soliton and bound state strings permuted by SL(2, Z ) and the space-time coordinates enter tantalizingly in the formalism as noncommuting matrices.

TL;DR: In this article, the authors present a systematic analysis of eleven-dimensional supergravity on a manifold with boundary, which is believed to be relevant to the strong coupling limit of the E 8 × E 8 heterotic string.

TL;DR: In this paper, it was argued that every Calabi-Yau manifold X with a mirror Y admits a family of supersymmetric toroidal 3-cycles and that the moduli space of such cycles together with their flat connections is precisely the space Y.

TL;DR: In this article, the leading logarithms for high-energy scattering can be obtained as a result of evolution of the non-local operators (straight-line ordered gauge factors) with respect to the slope of the straight line.

TL;DR: In this article, the full set of constraints on gluino and photino-mediated SUSY contributions to FCNC and CP violating phenomena are analyzed and a model-independent parameterization for the mass insertion method is provided.

TL;DR: In this article, the authors studied compactifications of F-theory on Calabi-Yau three-folds and showed that string/string duality in six dimensions gets mapped to fiber/base exchange in Ftheory.

TL;DR: In this article, it was shown that the quantum heterotic string has vacua with higher rank than is possible in conformal field theory, and that an extra SU (2) gauge symmetry appears that is supported in the core of the instanton.

TL;DR: In this paper, the equations for unbroken supersymmetry are expanded to the first non-trivial order, near this limit, verifying the consistency of the description and showing how, in some cases, if one tries to make Newton's constant too small, strong coupling develops in one of the two E8's.

TL;DR: In this paper, it was shown that configurations of multiple D-branes related by SU(N) rotations will preserve unbroken supersymmetry, including cases in which two Dbranes are related by a rotation of arbitrarily small angle.

TL;DR: In this article, the equivalence between F-theory on K3 and an orientifold of type IIB on T2 was established by a T-duality transformation to type I theory on T 2.

TL;DR: In this paper, the pressure and energy density of the SU(3) gauge theory are calculated on lattices with temporal extent N-tau = 4, 6 and 8 and spatial extent n-sigma = 16 and 32.

TL;DR: In this article, Liouville Field Theory (LFT) was shown to reproduce some of the predictions of the matrix model approach, in particular the scaling behavior, genus one partition functions, and integrated correlation functions.

TL;DR: The Coulomb branch of N = 2 supersymmetric gauge theories in four dimensions is described in general by an integrable Hamiltonian system in the holomorphic sense as mentioned in this paper.

TL;DR: In this paper, the implications of T -duality and extended gauge symmetry for the conjectured equivalence of heterotic and Type I superstrings were studied. But the results of the study were limited to the Dirichlet one-brane of Type I string theory.

TL;DR: In this paper, a Type-II D-brane description of a class of extremal and non-extremal five-dimensional Reissner-Nordstrom solutions and a corresponding set of degenerate Dbrane configurations were given.

TL;DR: In this article, Tate's algorithm was used to identify loci in the moduli of F-theory compactifications corresponding to enhanced gauge symmetry and to test the proposed Ftheory/heterotic dualities in six dimensions.

TL;DR: In this paper, the nonperturbative superpotential can be calculated in M-theory compactification to three dimensions on a Calabi-Yau four-fold X. The results carry over to certain Type IIB and heterotic string compactifications to four dimensions with N = 1 supersymmetry.

TL;DR: In this article, the authors re-analyze the subtraction method and point out the advantage of using angle and energy variables, which leads to simpler results and has complete generality, extending its validity to n-jet production.

TL;DR: In this article, the authors investigated baryogenesis from the coherent production of a scalar condensate along a flat direction of the supersymmetric extension of the standard model (Aflleck-Dine mechanism).

TL;DR: In this article, phase transitions are studied in M -theory and F-theory, where the non-geometrical phases known in conformal field theory are absent at boundaries of moduli space where such phases might have been expected, by a conventional or unconventional physical mechanism.

TL;DR: In this article, it was shown that for curved D-branes the corresponding sector is a (partially twisted) topological field theory, which is in accord with string duality and the fact that the left-moving ground state energy of the heterotic string starts at −1.

TL;DR: In this article, it was shown that in certain compactifications of M-theory on eight-manifolds to three-dimensional Minkowski space-time the four-form field strength can have a non-vanishing expectation value, while an N = 2 supersymmetry is preserved.

TL;DR: In this article, the singularities in the moduli space of string compactifications to six dimensions with N = 1 supersymmetry were studied and shown to arise from either massless particles or non-critical tensionless strings.

TL;DR: In this paper, the scaling dimensions of SU(2) N = 2 supersymmetric conformal field theories are analyzed in terms of the structure of relevant deformations of a y2 = x3 singular curve.

TL;DR: In this article, the Bekenstein-Hawking entropy of non-dilatonic p-branes with the dilaton constant throughout spacetime has been studied in various dimensions, including self-dual 3-brave and 2-and 5-braves.

TL;DR: In this paper, the authors present the results of the tree-level calculation of deepinelastic leptoproduction, including polarization of target hadron and produced hadron, and discuss the dependence on transverse momenta of the quarks which leads to azimuthal asymmetries for the produced hadrons.

TL;DR: In this paper, the role played by BPS states in the calculation of threshold corrections of D = 4, N = 2 heterotic string compactifications is clarified, and the relation of their results with string duality is discussed.

TL;DR: In this article, the authors show how the Riemann surface of N = 2 Yang-Mills field theory arises in type II string compactifications on Calabi-Yau threefolds.
