TL;DR: In this article, the existence of a horizon is intimately related with the requirement that the scalars are not constant, but given in terms of harmonic functions in analogy to the attractor flow in ungauged supergravity.
Abstract: We elaborate further on the static supersymmetric AdS4 black holes found in [1], investigating thoroughly the BPS constraints for spherical symmetry in N = 2 gauged supergravity in the presence of Fayet-Iliopoulos terms. We find Killing spinors that preserve two of the original eight supercharges and investigate the conditions for genuine black holes free of naked singularities. The existence of a horizon is intimately related with the requirement that the scalars are not constant, but given in terms of harmonic functions in analogy to the attractor flow in ungauged supergravity. The black hole charges depend on the choice of the electromagnetic gauging, with only magnetic charges for purely electric gaugings. Finally we show how these black holes can be embedded in N = 8 supergravity and thus in M-theory.

TL;DR: In this paper, a model-independent search for a narrow resonance produced in proton-proton collisions at square root(s) = 8 TeV and decaying to a pair of 125 GeV Higgs bosons that in turn each decays into bottom quark-antiquark pairs is performed by the CMS experiment at the LHC.

TL;DR: In this article, the production of J/psi mesons from b-hadron decays at the LHC was studied in pp collisions at 6.5 to 30 GeV/c and in three rapidity ranges.
Abstract: The production of J/psi mesons is studied in pp collisions at sqrt(s)=7 TeV with the CMS experiment at the LHC. The measurement is based on a dimuon sample corresponding to an integrated luminosity of 314 inverse nanobarns. The J/psi differential cross section is determined, as a function of the J/psi transverse momentum, in three rapidity ranges. A fit to the decay length distribution is used to separate the prompt from the non-prompt (b hadron to J/psi) component. Integrated over J/psi transverse momentum from 6.5 to 30 GeV/c and over rapidity in the range |y| < 2.4, the measured cross sections, times the dimuon decay branching fraction, are 70.9 \pm 2.1 (stat.) \pm 3.0 (syst.) \pm 7.8(luminosity) nb for prompt J/psi mesons assuming unpolarized production and 26.0 \pm 1.4 (stat.) \pm 1.6 (syst.) \pm 2.9 (luminosity) nb for J/psi mesons from b-hadron decays.

TL;DR: In this article, the authors explore the shadow of rotating traversable wormholes within classical general relativity and compare the results with the case of the Kerr black hole, showing that the shadows for small angular momenta are nearly identical; however, with the increasing of the angular momentum, they start to deviate considerably.
Abstract: We explore the shadow of a certain class of rotating traversable wormholes within classical general relativity. The images depend on the angular momentum of the wormhole and the inclination angle of the observer. We compare the results with the case of the Kerr black hole. For small angular momenta, the shadows for the two solutions are nearly identical; however, with the increasing of the angular momentum, they start to deviate considerably.

01 Jan 2000TL;DR: In this paper, a review on recent development in self-consistent description of high-frequency discharges is presented, based on fluid models of travelling-wave-sustained plasmas and results for the axial structure of discharges in different gases.
Abstract: A review on recent development in self-consistent description of high-frequency discharges is presented. The discussions are based on fluid models of travelling-wave-sustained plasmas and results for the axial structure of discharges in different gases. (© 2004 WILEY-VCH Verlag GmbH & Co.
