W Boson Polarisation at LEP2
The OPAL collaboration, G. Abbiendi
Elements of the spin density matrix for W bosons in e+e- -> W+W- -> qqln events are measured from data recorded by the OPAL detector at LEP. This information is used calculate pola…
Measurement of the partial widths of the Z into up- and down-type quarks
The OPAL collaboration, G. Abbiendi
Using the entire OPAL LEP1 on-peak Z hadronic decay sample, Z -> qbarq gamma decays were selected by tagging hadronic final states with isolated photon candidates in the electromag…
The charges of a twisted brane
Matthias R Gaberdiel, Terry Gannon
The charges of the twisted D-branes of certain WZW models are determined. The twisted D-branes are labelled by twisted representations of the affine algebra, and their charge is si…
An Automorphism of A Free Metabelian Group Without Fixed Points
Martin Kassabov
We construct an example of an IA-automorphism of the free metabelian group of rank without nontrivial fixed points. That gives a negative answer to the question raised by…
Maximal Bell's Inequality Violation for Non Maximal Entanglement
M. Kobayashi, F. Khanna, A. Mann +2
Bell's inequality violation (BIQV) for correlations of polarization is studied for a {\it product} state of two two-mode squeezed vacuum (TMSV) states. The violation allowed is sho…
See-Saw Induced CMSSM Lepton-Flavour Violation Post-WMAP
Bruce A. Campbell, David W. Maybury, Brandon Murakami
The see-saw mechanism of neutrino mass generation, when incorporated in supersymmetric theories with supergravity mediated supersymmetry breaking, results in low-energy lepton-flav…
Cosmic microwave background snapshots: pre-WMAP and post-WMAP
J. R. Bond, C. R. Contaldi, D. Pogosyan
Abbreviated: We highlight the remarkable evolution in the CMB power spectrum over the past few years, and in the cosmological parameters for minimal inflation models derived from i…
Triangle Anomaly and the Muon g-2
Andrzej Czarnecki, William J. Marciano, Arkady Vainshtein
Hadronic electroweak corrections to the muon anomalous magnetic moment (g-2) are reviewed. Emphasis is on clarification of discrepancies among various published studies. A theorem…
Experimental studies of unbiased gluon jets from e+e- annihilations using the jet boost algorithm
The OPAL collaboration, G. Abbiendi
We present the first experimental results based on the jet boost algorithm, a technique to select unbiased samples of gluon jets in e+e- annihilations, i.e. gluon jets free of bias…
Spin Torque and its Relation to Spin Filtering
Wonkee Kim, F. Marsiglio
The spin torque exerted on a magnetic moment is a reaction to spin filtering when spin-polarized electrons interact with a thin ferromagnetic film. We show that, for certain condit…
Classical and Quantum Decay of Oscillatons: Oscillating Self-Gravitating Real Scalar Field Solitons
Don N. Page
The oscillating gravitational field of an oscillaton of finite mass M causes it to lose energy by emitting classical scalar field waves, but at a rate that is non-perturbatively ti…
A Connes-amenable, dual Banach algebra need not have a normal, virtual diagonal
Volker Runde
Let be a locally compact group, and let denote the space of weakly almost periodic functions on . We show that, if is a -group, but not compact, then the…
Transport in vortex state of d-wave superconductors at zero temperature: Wiedemann-Franz violation
Wonkee Kim, F. Marsiglio, J. P. Carbotte
We show that the Wiedemann-Franz law is violated at zero temperature in the vortex state of a d-wave BCS superconductor with isotropic impurity scattering. We use a semiclassical a…
Self Adjoint Extensions of Phase and Time Operators
G. Gour, F. C. Khanna, M. Revzen
It is shown that any real and even function of the phase (time) operator has a self-adjoint extension and its relation to the general phase operator problem is analyzed.
Phase fluctuations of s-wave superconductors on a lattice
Wonkee Kim, J. P. Carbotte
Based on an attractive Hubbard model on a lattice with up to second neighbor hopping we derive an effective Hamiltonian for phase fluctuations. The superconducting gap is assum…
A Study of W+W-gamma Events at LEP
The OPAL collaboration, G. Abbiendi
A study of W+W- events accomanied by hard photon radiation produced in e+e- collisions at LEP is presented. Events consistent with being two on-shell W bosons and an isolated photo…
Self-Consistent Modification To The Electron Density Of States Due To Electron-Phonon Coupling In Metals
Fatih Dogan, Frank Marsiglio
The "standard" theory of a normal metal consists of an effective electron band which interacts with phonons and impurities. The effects due to the electron-phonon interaction are o…
Universal temperature corrections to the free energy for the gravitational field
G. E. Volovik, A. I. Zelnikov
The temperature correction to the free energy of the gravitational field is considered which does not depend on the Planck energy physics. The leading correction may be interpreted…
Periodic diffraction patterns for 1D quasicrystals
Pawel Buczek, Lorenzo Sadun, Janusz Wolny
A simple model of 1D structure based on a Fibonacci sequence with variable atomic spacings is proposed. The model allows for observation of the continuous transition between period…
Search for the Single Production of Doubly-Charged Higgs Bosons and Constraints on their Couplings from Bhabha Scattering
The OPAL collaboration, G. Abbiendi
A search for single production of doubly-charged Higgs bosons has been performed using 600.7 pb^-1 of e+e- collision data with sqrt(s)=189--209GeV collected by the OPAL detector at…
