What if the Mass Difference is around 18 Inverse Picoseconds?
A. Ali, D. London
Present experiments in pursuit of the mass difference in the Bs-Bs(bar) system have put a lower bound on this quantity of (at 95% C.L.). The same experiments…
Topological symmetry breaking and the confinement of anyons
P. W. Irwin, M. B. Paranjape
We study topological symmetry breaking via the behaviour of Wilson and 't Hooft loop operators for the 2+1 dimenesional Abelian-Higgs model with Chern-Simons term. The topological…
Exact Solvability of Superintegrable Systems
Piergiulio Tempesta, Alexander V. Turbiner, Pavel Winternitz
It is shown that all four superintegrable quantum systems on the Euclidean plane possess the same underlying hidden algebra . The gauge-rotated Hamiltonians, as well as thei…
Photometric and Spectroscopic Analysis of Cool White Dwarfs with Trigonometric Parallax Measurements
P. Bergeron, S. K. Leggett, Maria Teresa Ruiz
A photometric and spectroscopic analysis of 152 cool white dwarf stars is presented. The discovery of 7 new DA white dwarfs, 2 new DQ white dwarfs, 1 new magnetic white dwarf, and…
Two-dimensional algebro-geometric difference operators
Alexei A. Oblomkov, Alexei V. Penskoi
A generalized inverse problem for a two-dimensional difference operator is introduced. A new construction of the algebro-geometric difference operators of two types first considere…
Some families of special Lagrangian tori
Diego Matessi
We give a simple proof of the local version of a result of R. Bryant, stating that any 3-dimensional Riemannian manifold can be isometrically embedded as a special Lagrangian subma…
Exciton-phonon droplets with Bose-Einstein condensate: transport and optical properties
D. Roubtsov, Y. Lepine, I. Loutsenko
We discuss the possibility for a moving droplet of excitons and phonons to form a coherent state inside the packet. We describe such an inhomogeneous state in terms of Bose-Einstei…
Fission barriers of neutron-rich and superheavy nuclei calculated with the ETFSI method
A. Mamdouh, J. M. Pearson, M. Rayet +1
Using the ETFSI (extended Thomas-Fermi plus Strutinsky integral) method, we have calculated the fission barriers of nearly 2000 exotic nuclei, including all the neutron-rich nuclei…
Searching for New Physics via CP Violation in B -> pi pi
D. London, N. Sinha, R. Sinha
It is well known that one can use B -> pi pi decays to probe the CP-violating phase α. In this paper we show that these same decays can be used to search for new physics. This is d…
Measurement of the B0 Lifetime and Oscillation Frequency using B0->D*+l-v decays
The OPAL collaboration, G. Abbiendi
The lifetime and oscillation frequency of the B0 meson has been measured using B0->D*+l-v decays recorded on the Z0 peak with the OPAL detector at LEP. The D*+ -> D0pi+ decays were…
Geometric Phase of Three-level Systems in Interferometry
Barry C. Sanders, Hubert de Guise, Stephen D. Bartlett +1
We present the first scheme for producing and measuring an Abelian geometric phase shift in a three-level system where states are invariant under a non-Abelian group. In contrast t…
Unitary transformations for testing Bell inequalities
S. D. Bartlett, D. A. Rice, B. C. Sanders +2
It is shown that optical experimental tests of Bell inequality violations can be described by SU(1,1) transformations of the vacuum state, followed by photon coincidence detections…
Symplectic Structures on Fiber Bundles
Francois Lalonde, Dusa McDuff
Let be a locally trivial fiber bundle over a connected CW complex with fiber equal to the closed symplectic manifold $(M,\om)$. Then is said to be a symplectic…
A Measurement of the Rate of Charm Production in W Decays
The OPAL collaboration, G. Abbiendi
Using data recorded at centre-of-mass energies around 183 GeV and 189 GeV with the OPAL detector at LEP, the fundamental coupling of the charm quark to the W boson has been studied…
WW Production Cross Section and W Branching Fractions in e+e- Collisions at 189 GeV
The OPAL collaboration, G. Abbiendi
From a data sample of 183 pb^-1 recorded at a center-of-mass energy of roots = 189 GeV with the OPAL detector at LEP, 3068 W-pair candidate events are selected. Assuming Standard M…
Measurement of the Mass and Width of the W Boson in e+e- Collisions at 189 GeV
The OPAL collaboration, G. Abbiendi
The mass and width of the W boson are determined in e+e- collisions at LEP using 183 pb^-1 of data recorded at a centre-of-mass energy roots=189 GeV with the OPAL detector. The inv…
The Impact of External Tidal Fields on the ISM of Dwarf Spheroidals
Sergey Mashchenko, Claude Carignan
It was found that for three dwarf spheroidal galaxies - Sculptor, Tucana, and Cetus - there is a correspondence between the distribution of associated HI gas and the projected tida…
A near-IR [Fe II] line imaging survey of supernova remnants in M33
T. Morel, R. Doyon, N. St-Louis
We report on the first near-IR [Fe II] line imaging survey of extragalactic SNRs. Observations of a sample of 42 objects drawn from an optically-selected catalogue of SNRs in M33 p…
