The mixmaster universe: A chaotic Farey tale
Neil Cornish, Janna Levin
When gravitational fields are at their strongest, the evolution of spacetime is thought to be highly erratic. Over the past decade debate has raged over whether this evolution can…
The tale of two centres
Neil Cornish, Gary Gibbons
We study motion in the field of two fixed centres described by a family of Einstein-dilaton-Maxwell theories. Transitions between regular and chaotic motion are observed as the dil…
The correlation function of radio sources
A. J. Loan, J. V. Wall, O. Lahav
We investigate the large-scale clustering of radio sources in the Green Bank and Parkes-MIT-NRAO 4.85 GHz surveys by measuring the angular two-point correlation function w(θ). Excl…
Classical Monopoles: Newton, NUT-space, gravomagnetic lensing and atomic spectra
Donald Lynden-Bell, Mohammad Nouri-Zonoz
Stimulated by a scholium in Newton's Principia we find some beautiful results in classical mechanics which can be interpreted in terms of the orbits in the field of a mass endowed…
signals at LEP2 energies in the Minimal Supersymmetric Standard Model
S. Moretti, K. Odagiri
In this paper we compare and into four-fermion production at centre-of-mass energies typical of LEP2 and somewhat larger. The theoretical framework considered is…
Non-Perturbative Corrections to Heavy Quark Fragmentation in e^+e^- Annihilation
P. Nason, B. R. Webber
We estimate the non-perturbative power-suppressed corrections to heavy flavour fragmentation and correlation functions in e^+e^- annihilation, using a model based on the analysis o…
Evidence for strong electron-phonon coupling and polarons in the optical response of La_{2-x}Sr_xCuO_4
O. V. Dolgov, H. J. Kaufmann, E. K. H. Salje +1
The normal state optical response of La_{2-x}Sr_xCuO_4 is found to be consistent with a simple multi-component model, based on free carriers with strong electron-phonon interaction…
Cygnus X-3 in outburst : quenched radio emission, radiation losses and variable local opacity
R. P. Fender, S. J. Bell Burnell, E. B. Waltman +3
We present multiwavelength observations of Cygnus X-3 during an extended outburst in 1994 February - March. Intensive radio monitoring at 13.3, 3.6 & 2.0 cm is complemented by obse…
The twelve dimensional super (2+2)-brane
S. F. Hewson, M. J. Perry
We discuss supersymmetry in twelve dimensions and present a covariant supersymmetric action for a brane with worldsheet signature (2,2), called a super (2+2)-brane, propagating in…
Radiation-Driven Warping: The Origin of Warps and Precession in Accretion Disks
Philip R. Maloney, Mitchell C. Begelman, J. E. Pringle
A geometrically thin, optically thick, warped accretion disk with a central source of luminosity is subject to non-axisymmetric forces due to radiation pressure; the resulting torq…
Higgs Production at the LHC: an Updated Signal-to-Background Analysis
S. Moretti
This paper follows hep-ph/9611397, where updated calculations of cross sections and branching ratios relevant for Standard Model Higgs phenomenology at the LHC were presented. Here…
Artificial Neural Networks as a Tool for Galaxy Classification
Ofer Lahav
We describe an Artificial Neural Network (ANN) approach to classification of galaxy images and spectra. ANNs can replicate the classification of galaxy images by a human expert to…
Minimal Length Uncertainty Relation and Ultraviolet Regularisation
A. Kempf, G. Mangano
Studies in string theory and quantum gravity suggest the existence of a finite lower limit to the possible resolution of distances, at the latest on the scale of the Planck…
CFRS XIV: Spectral Properties Of Field Galaxies Up To z = 1
F. Hammer, H. Flores, S. J. Lilly +6
The spectral properties of more than 400 CFRS galaxies and their changes over the redshift interval 0 - 1.3 are investigated. Emission line intensities and equivalent widths for ac…
Hamiltonian Reduction of Diffeomorphism Invariant Field
Jens Hoppe, Tudor Ratiu
For a variety of diffeomorphism-invariant field theories describing hypersurface motions (such as relativistic M-branes in space-time dimension M+2) we perform a Hamiltonian reduct…
Building Blocks in Turaev-Viro Theory
Radu Ionicioiu
We study the form of the Turaev-Viro partition function Z(M) for different 3-manifolds with boundary. We show that for boundaries Z(M) factorizes into a term which contains t…
Revisiting Bell's theorem for a class of down-conversion experiments
Sandu Popescu, Lucien Hardy, Marek Zukowski
A certain class of parametric down-conversion Bell type experiments has the following features. In the idealized perfect situation it is in only 50% of cases that each observer rec…
Graded contractions and bicrossproduct structure of deformed inhomogeneous algebras
J. A. de Azcarraga, M. del Olmo, J. C. Perez Bueno +1
A family of deformed Hopf algebras corresponding to the classical maximal isometry algebras of zero-curvature N-dimensional spaces (the inhomogeneous algebras iso(p,q), p+q=N, as w…
Central Extensions of the Quasi-orthogonal Lie algebras
J. A. de Azcarraga, F. J. Herranz, J. C. Perez Bueno +1
We determine the central extensions of a whole family of Lie algebras, obtained by the method of graded contractions from so(N+1), N arbitrary. All the inhomogeneous orthogonal and…
Superstring dualities and p-brane bound states
M. S. Costa, G. Papadopoulos
We show that the M-theory/IIA and IIA/IIB superstring dualities together with the diffeomorphism invariance of the underlying theories require the presence of certain p-brane bound…
The Z_2-graded Schouten-Nijenhuis bracket and generalized super-Poisson structures
J. A. de Azcarraga, J. M. Izquierdo, A. M. Perelomov +1
The super or Z_2-graded Schouten-Nijenhuis bracket is introduced. Using it, new generalized super-Poisson structures are found which are given in terms of certain graded-skew-symme…
Dissipating Cosmic Vortons and Baryogenesis
Anne-Christine Davis, Warren B. Perkins
Grand unified theories can admit cosmic strings with fermion zero modes which result in the string carrying a current and the formation of stable remnants, vortons. We consider the…
Maximum Information and Quantum Prediction Algorithms
Jim McElwaine
This paper describes an algorithm for selecting a consistent set within the consistent histories approach to quantum mechanics and investigates its properties. The algorithm uses a…
