Direct Observation of Dynamical Switching between Two Driven Oscillation States of a Josephson Junction
I. Siddiqi, R. Vijay, F. Pierre +8
We performed a novel phase sensitive microwave reflection experiment which directly probes the dynamics of the Josephson plasma resonance in both the linear and non-linear regime.…
Measurements of Branching Fractions and CP-Violating Asymmetries in B Meson Decays to Charmless Two-Body States Containing a K0
B. Aubert, BABAR Collaboration
We present measurements of branching fractions and \CP-violating asymmetries in decays of mesons to two-body final states containing a \Kz. The results are based on a data samp…
XMM-Newton observations of Sagittarius A East
Masaaki Sakano, Robert S. Warwick, Anne Decourchelle +1
We present an analysis of a recent XMM-Newton observation of Sgr A East, a supernova remnant located close to the Galactic Centre. Very high quality X-ray spectra reveal many emiss…
Measurement of the Branching Fraction for B- --> D0 K*-
B. Aubert, BABAR Collaboration
We present a measurement of the branching fraction for the decay B- --> D0 K*- using a sample of approximately 86 million BBbar pairs collected by the BaBar detector from e+e- coll…
Towards complete string effective actions beyond leading order
Kasper Peeters, Pierre Vanhove, Anders Westerberg
We review the current knowledge of higher-derivative terms in string effective actions, the various approaches that have been used to obtain them and their applications.
Remarks on transient photon production in heavy ion collisions
E. Fraga, F. Gelis, D. Schiff
In this note, we discuss the derivation of a formula that has been used in the literature in order to compute the number of photons emitted by a hot or dense system during a finite…
Structural and scaling properties of galaxy clusters: probing the physics of structure formation
M. Arnaud, G. W. Pratt, E. Pointecouteau
We present XMM-Newton studies of the total mass, gas density, temperature and entropy profiles in nearby hot and cool clusters, together with follow-up observations of distant clus…
The complete experiment for elastic scattering in presence of two-photon exchange
M. P. Rekalo, E. Tomasi-Gustafsson
We propose possible methods to measure the nucleon electromagnetic form factors in presence of two-photon exchange. Using a general parametrization of the spin structure of the mat…
Bethe Ansatz calculation of the spectral gap of the asymmetric exclusion process
O. Golinelli, K. Mallick
We present a new derivation of the spectral gap of the totally asymmetric exclusion process on a half-filled ring of size L by using the Bethe Ansatz. We show that, in the large L…
From exact-WKB towards singular quantum perturbation theory
André Voros
We use exact WKB analysis to derive some concrete formulae in singular quantum perturbation theory, for Schrödinger eigenvalue problems on the real line with polynomial potentials…
Measurement of Cosmic Shear with the Space Telescope Imaging Spectrograph
Jason Rhodes, Alexandre Refregier, Nicholas R. Collins +3
Weak lensing by large-scale structure allows a direct measure of the dark matter distribution. We have used parallel images taken with the Space Telescope Imaging Spectrograph (STI…
XMM-Newton Observations of the Ultraluminous Nuclear X-ray Source in M33
L. Foschini, J. Rodriguez, Y. Fuchs +5
We present observations with XMM-Newton of M33 X-8, the ultraluminous X-ray source (L_{0.5-10 keV} ~ 2x10^39 erg/s) closest to the centre of the galaxy. The best-fit model is simil…
Measurement of Branching Fractions and Charge Asymmetries in B+ --> rho+pi0 and B+ -->rho0pi+ Decays, and Search for B0 --> rho0pi0
B. Aubert
We present measurements of branching fractions and charge asymmetries in -meson decays to , and . The data sample comprises $Υ(4S)…
Hints for a fast precessing relativistic radio jet in LS I +61 303
M. Massi, M. Ribo, J. M. Paredes +3
Here we discuss two consecutive MERLIN observations of the X-ray binary LS I +61 303. The first observation shows a double-sided jet extending up to about 200 AU on both sides of a…
Effects of dissipation on disordered quantum spin models
L. F. Cugliandolo, D. R. Grempel, G. Lozano +1
We study the effects of the coupling to an Ohmic quantum reservoir on the static and dynamical properties of a family of disordered SU(2) spin models in a transverse magnetic field…
Boundary Ground Ring in 2D String Theory
Ivan K. Kostov
The 2D quantum gravity on a disc, or the non-critical theory of open strings, is known to exhibit an integrable structure, the boundary ground ring, which determines completely the…
DPEMC : A Monte-Carlo for Double Diffraction
Maarten Boonekamp, Tibor Kucs
We extend the POMWIG Monte Carlo generator developed by B.Cox and J.Forshaw, to include new models of central production through inclusive and exclusive Double Pomeron Exchange in…
Saturation at Hadron Colliders
C. Marquet, R. Peschanski
We extend the saturation models a la Golec-Biernat and Wusthoff to cross-sections of hard processes initiated by virtual-gluon probes separated by large rapidity intervals at hadro…
The \bar q q Bound States and Instanton Molecule at T >~ T_c
Gerald E. Brown, Chang-Hwan Lee, Mannque Rho +1
The main objective of this work is to explore the evolution in the structure of the quark-anti-quark bound states in going down in the chirally restored phase from the so-called "z…
Effect of interactions on the noise of chiral Luttinger liquid systems
B. Trauzettel, P. Roche, D. C. Glattli +1
We analyze the current noise, generated at a quantum point contact in fractional quantum Hall edge state devices, using the chiral Luttinger liquid model with an impurity and the a…
Cooperativity in sandpiles: statistics of bridge geometries
Anita Mehta, G. C. Barker, J. M. Luck
Bridges form dynamically in granular media as a result of spatiotemporal inhomogeneities. We classify bridges as linear and complex, and analyse their geometrical characteristics.…
