A Holographic Interpretation of Asymptotically de Sitter Spacetimes
A. J. M. Medved
One of the remarkable outcomes of the AdS/CFT correspondence has been the generalization of Cardy's entropy formula for arbitrary dimensionality, as well as a variety of anti-de Si…
Thorny Spheres and Black Holes with Strings
V. P. Frolov, D. V. Fursaev, D. N. Page
We consider thorny spheres, that is 2-dimensional compact surfaces which are everywhere locally isometric to a round sphere except for a finite number of isolated points wher…
Expansion of bound state energies in powers of m/M and (1-m/M)
Ian Blokland, Andrzej Czarnecki, Kirill Melnikov
Elaborating on a previous letter, we use a new approach to compute energy levels of a non-relativistic bound-state of two constituents, with masses m and M, by systematic expansion…
Semileptonic b --> u decays: lepton invariant mass spectrum
Andrzej Czarnecki, Kirill Melnikov
We compute O(alpha_s^2) QCD corrections to the lepton invariant mass spectrum in the decay b --> u l nu_l, relevant for the determination of the CKM matrix element |V_{ub}|. Our me…
Search for Leptoquarks in Electron-Photon Scattering at sqrt(s_ee) up to 209 GeV at LEP
The OPAL collaboration, G. Abbiendi
Searches for first generation scalar and vector leptoquarks, and for squarks in R-parity violating SUSY models with the direct decay of the squark into Standard Model particles, ha…
Near-Extremal Spherically Symmetric Black Holes in an Arbitrary-Dimensional Spacetime
A. J. M. Medved
In a recent paper (hep-th/0111091), the near-extremal thermodynamics of a 4-dimensional Reissner-Nordstrom black hole had been considered. In the current letter, we extend this pri…
A Note on Holography on a Curved Brane
A. J. M. Medved
Some recent literature has examined the holographic-induced cosmology of a brane universe in the background of an anti-de Sitter-black hole geometry. In this regard, curved-brane s…
On Algebraic Hyperbolicity of Log Varieties
Xi Chen
Fix a very general hypersurface D in P^n of degree at least 2n + 1 and we show that the complement P^n - D does not contain any algebraic torus C^*.
Stochastic Production Of Kink-Antikink Pairs In The Presence Of An Oscillating Background
Rajarshi Ray, Supratim Sengupta
We numerically investigate the production of kink-antikink pairs in a dimensional field theory subject to white noise and periodic driving. The twin effects of noise…
Pion pole contribution to hadronic light-by-light scattering and muon anomalous magnetic moment
Ian Blokland, Andrzej Czarnecki, Kirill Melnikov
We derive an analytic result for the pion pole contribution to the light-by-light scattering correction to the anomalous magnetic moment of the muon, . Using the ve…
dS/CFT Duality on the Brane with a Topological Twist
A. J. M. Medved
We consider a brane universe in an asymptotically de Sitter background spacetime of arbitrary dimensionality. In particular, the bulk spacetime is described by a ``topological de S…
On quasi-affine transforms of Read's operator
Thomas Schlumprecht, Vladimir G. Troitsky
We show that C.J.Read's example of an operator T on l_1 which does not have any non-trivial invariant subspaces is not the adjoint of an operator on a predual of l_1. Furthermore,…
A Thermodynamical Approach to Quantifying Quantum Correlations
Jonathan Oppenheim, Michal Horodecki, Pawel Horodecki +1
We consider the amount of work which can be extracted from a heat bath using a bipartite state shared by two parties. In general it is less then the amount of work extractable when…
An Exactly Conservative Integrator for the n-Body Problem
Oksana Kotovych, John C. Bowman
The two-dimensional n-body problem of classical mechanics is a non-integrable Hamiltonian system for n > 2. Traditional numerical integration algorithms, which are polynomials in t…
Single-spin azimuthal asymmetry in exclusive electroproduction of pi^+ mesons
HERMES Collaboration, A. Airapetian
A single-spin asymmetry in the distribution of exclusively produced pi^+ mesons azimuthally around the virtual photon direction relative to the lepton scattering plane has been mea…
CFT on the Brane with a Reissner-Nordstrom-de Sitter Twist
A. J. M. Medved
We consider a brane universe in a Reissner-Nordstrom-de Sitter background spacetime of arbitrary dimensionality. It is shown that the brane evolution is described by generalized Fr…
First Order Radiative Corrections to Polarized Muon Decay Spectrum
A. B. Arbuzov
The first order QED corrections to the polarized muon decay spectrum are considered. The exact dependence on electron and muon masses is kept. Numerical results are presented.
Reissner-Nordstrom Near Extremality from a Jackiw-Teitelboim Perspective
A. J. M. Medved
In this paper, we investigate the near-extremal thermodynamics of the Reissner-Nordstrom (RN) black hole. Our methodology is based on a duality that exists between the near-horizon…
Search for Doubly Charged Higgs Bosons with the OPAL detector at LEP
The OPAL collaboration, G. Abbiendi
A search for pair-produced doubly charged Higgs bosons has been performed using data samples corresponding to an integrated luminosity of about 614 pb-1 collected with the OPAL det…
Brick Walls on the Brane
A. J. M. Medved
The so-called ``brick-wall model'' is a semi-classical approach that has been used to explain black hole entropy in terms of thermal matter fields. Here, we apply the brick-wall fo…
(Conformal) Killing vectors in the Newman-Penrose formalism
Garry Ludwig, S. Brian Edgar
This paper presents an efficient technique for finding Killing, homothetic, or even proper conformal Killing vectors in the Newman-Penrose (NP) formalism. Leaning on, and extending…
Connes-amenability and normal, virtual diagonals for measure algebras, II
Volker Runde
We prove that the following are equivalent for a locally compact group : (i) is amenable; (ii) is Connes-amenable; (iii) has a normal, virtual diagonal.
Connes-amenability and normal, virtual diagonals for measure algebras, I
Volker Runde
We prove that the measure algebra of a locally compact group is Connes-amenable if and only if is amenable.
Operator Figa-Talamanca-Herz algebras
Volker Runde
Let G be a locally compact group. We use the canonical operator space structure on the spaces for introduced by G. Pisier to define operator space analo…
