Measurements of the branching fractions and CP-asymmetries of B- --> D0_(CP) K- decays
The BABAR Collaboration, B. Aubert
We present a study of the decay B- --> D0_(CP) K- and its charge conjugate, where D0_(CP) is reconstructed in CP-even, CP-odd, and non-CP flavor eigenstates, based on a sample of 2…
Search for rare quark-annihilation decays, B --> Ds(*) Phi
The BABAR Collaboration, B. Aubert
We report on searches for B- --> Ds- Phi and B- --> Ds*- Phi. In the context of the Standard Model, these decays are expected to be highly suppressed since they proceed through ann…
Supersymmetry Parameter Analysis: SPA Convention and Project
J. A. Aguilar-Saavedra, A. Ali, B. C. Allanach +122
High-precision analyses of supersymmetry parameters aim at reconstructing the fundamental supersymmetric theory and its breaking mechanism. A well defined theoretical framework is…
Bayesian updating of a probability distribution encoded on a quantum register
Andrei N. Soklakov, Ruediger Schack
We investigate the problem of Bayesian updating of a probability distribution encoded in the quantum state of n qubits. The updating procedure takes the form of a quantum algorithm…
Classical predictability and coarse-grained evolution of the quantum baker's map
Artur Scherer, Andrei N. Soklakov, Ruediger Schack
We investigate how classical predictability of the coarse-grained evolution of the quantum baker's map depends on the character of the coarse-graining. Our analysis extends earlier…
Superconducting phase coherent electron transport in proximity conical ferromagnets

We report superconducting phase-periodic conductance oscillations in ferromagnetic wires with interfaces to conventional superconductors. The ferromagnetic wires were made of Ho, a…
The Linear Arrangement Problem Parameterized Above Guaranteed Value
G. Gutin, A. Rafiey, S. Szeider +1
A linear arrangement (LA) is an assignment of distinct integers to the vertices of a graph. The cost of an LA is the sum of lengths of the edges of the graph, where the length of a…
Measurement of the production cross-section of positive pions in p-Al collisions at 12.9 GeV/c
HARP Collaboration
A precision measurement of the double-differential production cross-section, , for pions of positive charge, performed in the HARP experiment is presented.…

Minimum Cost and List Homomorphisms to Semicomplete Digraphs
G. Gutin, A. Rafiey, A. Yeo
The following optimization problem was introduced in \cite{gutinDAM}, where it was motivated by a real-world problem in defence logistics. Suppose we are given a pair of digraphs $…
Decoherence in a superconducting quantum bit circuit
G. Ithier, E. Collin, P. Joyez +8
Decoherence in quantum bit circuits is presently a major limitation to their use for quantum computing purposes. We present experiments, inspired from NMR, that characterise decohe…
Beam Profile Measurements and Simulations of the PETRA Laser-Wire
J. Carter, I. Agapov, G. A. Blair +13
The Laser-wire will be an essential diagnostic tool at the International Linear Collider. It uses a finely focussed laser beam to measure the transverse profile of electron bunches…

Tobias J. Osborne
In this Letter we show that an arbitrarily good approximation to the propagator e^{itH} for a 1D lattice of n quantum spins with hamiltonian H may be obtained with polynomial compu…
