  • 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. ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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. ...
  • 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 ...
  • 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 ...
  • 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 ...
