  • Koch, Robert de Mello; Graham, Stuart; Messamah, Ilies (Springer, 2014-02-28)
    In this article we study the action of the one loop dilatation operator on operators with a classical dimension of order N. These operators belong to the su(2) sector and are constructed using two complex fields Y and Z. ...
  • Brummer, Felix; McGarrie, Moritz; Weiler, Andreas (Springer, 2014-04-10)
    We study models of gauge-mediated supersymmetry breaking with a gauged horizontal SU(3)F symmetry acting on the quark superfields. If SU(3)F is broken nonsupersymmetrically by F -term vacuum expectation values, the massive ...
  • Giataganasa, Dimitrios; Soltanpanahib, Hesam (Springer, 2014-06-09)
    We study the Langevin diffusion of a relativistic heavy quark in anisotropic strongly coupled theories in the local limit. Firstly, we use the axion space-dependent deformed anisotropic N = 4 sYM, where the geometry ...
  • Abela, Steven; McGarrie, Moritz (Springer, 2014-07-29)
    We show how gauged flavour breaking and N = 1 supersymmetry breaking can be dynamically aligned to produce natural models. Supersymmetry is broken in a metastable vacuum, while a weakly gauged flavour symmetry is identified ...
  • Abdalgabar, Ammar; Cornell, Alan S.; Deandrea, Aldo; McGarrie, Moritz (Springer, 2014-07-31)
    Even if the unification and supersymmetry breaking scales are around 106 to 109 TeV, a large A t coupling may be entirely generated at low energies through RGE evolution in the 5D MSSM. Independent of the precise details ...
  • Goldstein, Kevin; Nampuri, Suresh; V´eliz-Osorio, Alvaro (Springer, 2014-08-26)
    In this note, we explore the solution space of non-extremal black objects in 4D and 5D N = 2 gauged supergravity in the presence of fluxes. We present first order rewritings of the 4D action for a classes of non-extremal ...
  • Cardoso, Gabriel Lopes; Ciraficia, Michele; Nampurib, Suresh (Springer, 2014-10-03)
    In this note, we employ indefinite theta functions to regularize canonical partition functions for single-center dyonic BPS black holes. These partition functions count dyonic degeneracies in the Hilbert space of ...
  • Bhattacharyya, Arpan; Haque, S. Shajidul; Jejjala, Vishnu; Nampuri, Suresh; Véliz-Osorio, Álvaro (Springer, 2014-11-24)
    Using the attractor mechanism for extremal solutions in N = 2 gauged supergravity, we construct a c-function that interpolates between the central charges of theories at ultraviolet and infrared conformal fixed points ...
  • Abdalgabar, A.; Cornell, A.S.; Deandrea, A.; McGarrie, M. (Springer Verlag, 2016-01)
    We explore unification and natural supersymmetry in a five dimensional extension of the standard model in which the extra dimension may be large, of the order of 1–10 TeV. Power law running generates a TeV scale At term ...
  • Zayas, L.A.P.; Rodgers, V.G.J.; Whiting, C.A. (Springer, 2016-02)
    We present a large class of new backgrounds that are solutions of type II supergravity with a warped AdS(4) factor, non-trivial axion-dilaton, B-field, and three-and five-form Ramond-Ramond fluxes. We obtain these solutions ...
  • de Mello Koch, R.; Mathwin, C.; Van Zyl, H.J.R. (Springer Verlag, 2016-03)
    We consider excitations of LLM geometries described by coloring the LLM plane with concentric black rings. Certain closed string excitations are localized at the edges of these rings. The string theory predictions for the ...
  • Angus, S.; Matti, C.; Svanes, E.E. (Springer Verlag, 2016-03)
    We continue the investigation into non-maximally symmetric compactifications of the heterotic string. In particular, we consider compactifications where the internal space is allowed to depend on two or more external ...
  • de Mello Koch, R.; Tahiridimbisoa, N.H.; Mathwin, C. (Springer Verlag, 2016-03)
    We study spin chains with boundaries that are dual to open strings suspended between systems of giant gravitons and dual giant gravitons. Motivated by a geometrical interpretation of the central charges of su(2|2), we ...
  • He, Y.-H.; Jejjala, V.; Matti, C.; Nelson, B.D. (Springer Verlag, 2016-03)
    We present a complete classification of the vacuum geometries of all renormalizable superpotentials built from the fields of the electroweak sector of the MSSM. In addition to the Severi and affine Calabi-Yau varieties ...
  • de Mello Koch, R.; Ramgoolam, S. (Springer Verlag, 2016-03)
    In a recent paper we showed that the correlators of free scalar field theory in four dimensions can be constructed from a two dimensional topological field theory based on so(4, 2) equivariant maps (intertwiners). The free ...
  • Goldstein, K.; Jejjala, V.; Nampuri, S. (Springer Verlag, 2016-04)
    Non-extremal black holes in (Formula presented.) supergravity have two horizons, the geometric mean of whose areas recovers the horizon area of the extremal black hole obtained from taking a smooth zero temperature limit. ...
  • Athenodorou, A.; Bennett, E.; Bergner, G.; Elander, D.; Lin, C.-J.D.; Lucini, B.; Piai, M. (Springer Verlag, 2016-06)
    Besides the Higgs particle discovered in 2012, with mass 125 GeV, recent LHC data show tentative signals for new resonances in diboson as well as diphoton searches at high center-of-mass energies (2 TeV and 750 GeV, ...
  • Bizet, N.C; Loaiza-Brito, O.; Zavala, I (Springer Verlag, 2016-10)
    We study the moduli space of type IIB string theory flux compactifications on the mirror of the CY quintic 3-fold in ℙ 4. We focus on the dynamics of the four dimensional moduli space, defined by the axio-dilaton τ and the ...
  • Mutuma, B.K.; Matsoso, B.J.; Ranganathan, K.; Wamwangi, D.; Coville, N.J; Keartland, J. (Royal Society of Chemistry, 2017)
    Solid carbon spheres (CSs, d ≈ 200 nm) were synthesized (yield, <40%) in a vertically oriented chemical vapor deposition (CVD) reactor using acetylene as a carbon source and Ar or H2 as the carrier gas. The CSs synthesized ...
  • Kumar, M.; Ruan, X.; Islam, R.; Klein, M.; Klein, U.; Mellado, B.; Cornell, A.S. (Elsevier, 2017-01)
    A proposed high energy Future Circular Hadron-Electron Collider would provide sufficient energy in a clean environment to probe di-Higgs production. Using this channel we show that the azimuthal angle correlation between ...
