TL;DR: In this article, a world-sheet sigma model is applied to string theories dual to four-dimensional gauge theories, and semi-classical soliton solutions representing highly excited string states are identified which correspond to gauge theory operators with relatively small anomalous dimensions.

TL;DR: In this article, a general analysis of extensions of the Standard Model which satisfy the criterion of Minimal Flavour Violation (MFV) is presented, with the most stringent constraints imposed by B → Xsγ.

TL;DR: In this article, the total cross-section for direct Higgs boson production in hadron collisions at NNLO in perturbative QCD was computed, based on the Cutkosky rules, integration by parts and the differential equation method for computing master integrals.

TL;DR: In this article, the covariant κ-symmetric superstring action for type IIB superstring on plane wave space supported by Ramond-Ramond background is defined as a 2d sigma-model on the coset superspace.

TL;DR: In this article, the authors considered the pre-Big-Bang scenario with a massive axion field which starts to dominate energy density when oscillating in an instanton-induced potential and subsequently reheats the universe as it decays into photons, thus creating adiabatic CMB perturbations.

TL;DR: In this paper, it was shown that B-model topological strings on local Calabi-Yau threefolds are large-N duals of matrix models, which in the planar limit naturally give rise to special geometry.

TL;DR: In this paper, the authors extended the formulation of soft-collinear effective theory, previously worked out to leading order, to second order in a power series in the inverse of the hard scale.

TL;DR: In this paper, it was shown that there is a bijective correspondence between equivalence classes of asymptotic reducibility parameters and (n−2)-forms in the context of Lagrangian gauge theories.

TL;DR: A survey of massless HS theories with 32 supersymmetries in D =4,5,7 (where the 7D results are new) is given and corresponding composite operators are discussed in this paper.

TL;DR: In this paper, it was shown that near-extremal black holes are obtained by exciting the Ramond sector of the D1-D5 CFT, where the ground state is highly degenerate.

TL;DR: In this article, the relation between matrix models, topological strings and N = 1 supersymmetric gauge theories was studied and it was shown that by considering double scaling limits of unitary matrix models one can obtain large-N duals of the local Calabi-Yau geometries that engineer N = 2 gauge theories.

TL;DR: In this paper, the dipole subtraction method for calculating next-to-leading order corrections in QCD was extended to include massive partons, namely quarks, squarks and gluinos.

TL;DR: In this article, the authors present results on the QCD phase diagram for μ B ⩽ πT with an imaginary chemical potential μ = iμ I for which the fermion determinant is positive.

TL;DR: In this paper, a solution to the nonlinear small-x "projectile side" evolution equations as derived by Balitskii in 1996 is presented, based on functional Fokker-Planck methods.

TL;DR: In this paper, the authors investigated the charged Schwarzschild-anti-de-Sitter (SAdS) BH thermodynamics in 5d Einstein-Gauss-Bonnet gravity with electromagnetic field.

TL;DR: In this article, the potential of a static quark-anti-quark pair in the range 0.05 -0.8 -fm was investigated using a sequence of lattices up to 64 4.

TL;DR: In this article, rational conformal field theory is formulated in terms of a symmetric special Frobenius algebra A and its representations, which is an algebra in the modular tensor category of Moore-Seiberg data of the underlying chiral CFT.

TL;DR: In this article, the authors studied three-flavor neutrino oscillations in the early universe and found that effective flavor equilibrium between all active neutrinos species is established well before the big-bang nucleosynthesis (BBN) epoch.

TL;DR: In this article, the dynamics of a large class of N = 1 quiver theories, geometrically realized by type IIB D-brane probes wrapping cycles of local Calabi-Yau three-folds, are studied.

TL;DR: In this article, a review of recent results on QCD at finite temperature is presented, with a discussion of observables which are of immediate interest to experimental searches for the Quark Gluon Plasma.

TL;DR: In this article, it was shown that the evolution equations in QCD predict geometric scaling for quark and gluon distribution functions in a large kinematical window, which extends above the saturation scale up to momenta Q 2 of order 100GeV 2.

TL;DR: In this paper, it was shown that a subset of non-planar diagrams of arbitrary genus survive and that a non-trivial double scaling limit may be defined for chiral primaries.

TL;DR: In this article, the implications of thermal leptogenesis for neutrino parameters were studied and it was shown that quasi-degenerate neutrinos are incompatible with thermal leptonogenesis.

TL;DR: In this article, superconformal transformations for the N = 2,4 supermultiplets corresponding to the simplest chiral primary operators are derived for two-, three-and four-point correlation functions.

TL;DR: In this article, the energy dependence of the saturation momentum in the presence of saturation boundaries limiting the region of linear BFKL evolution was studied and it was shown that the scaling of the scattering amplitude is valid in a wide range of momenta for fixed coupling evolution and in a more restricted region for running coupling evolution.

TL;DR: In this article, the cross section for leptoproduction of the real photon off the nucleon, which is sensitive to the deeply virtual Compton scattering amplitude with power accuracy, is computed.

TL;DR: In this paper, the equivalence between the Chern-Simons gauge theory on S-3 and the topological closed string theory on the resolved conifold geometry was shown.

TL;DR: In this paper, the authors investigated correlations between basic properties of the mean field models and the neutron skin thickness in lead, and found that conventional covariant models are too limited to explain the variations in mean field predictions of neutron radii.

TL;DR: In this paper, the physics potential of planned superbeams with the one of neutrino factories is compared, and the experimental setups as well as the most relevant uncertainties and errors are considered on the same footing as much as possible.

TL;DR: In this paper, the covariant coupled-channel Bethe-salpeter equation with the interaction kernel truncated at chiral order Q 3 was solved, where only those terms which are leading in the large-N c limit of QCD were included.
