Search for anomalous top quark couplings with the D0 detector
D0 Collaboration, V. Abazov
Anomalous Wtb couplings modify the angular correlations of the top quark decay products and change the single top quark production cross section. We present limits on anomalous top…
Search for -mesic nuclei in recoil-free transfer reaction
GEM Collaboration, A. Budzanowski
We have studied the reaction at recoil-free kinematics. An meson possibly produced in this reaction would be thus almost at rest in the labora…
A Sensitive Search For [NII] Emission in a z=6.4 Quasar Host Galaxy
F. Walter, A. Weiss, D. A. Riechers +4
We present a sensitive search for the ^3P_1->^3P_0 ground state fine structure line at 205 microns of ionized nitrogen ([NII]) in one of the highest redshift quasars (J1148+5251 at…
Measurement of D+- and D0 production in deep inelastic scattering using a lifetime tag at HERA
ZEUS Collaboration, S. Chekanov
The production of D+- and D0 mesons has been measured with the ZEUS detector at HERA using an integrated luminosity of 133.6 pb-1. The measurements cover the kinematic range 5 < Q^…
Active Galactic Nuclei: Sources for ultra high energy cosmic rays?
P. L. Biermann, J. K. Becker, L. Caramete +11
The origin of ultra high energy cosmic rays promises to lead us to a deeper understanding of the structure of matter. This is possible through the study of particle collisions at c…
New CO detections of lensed submillimeter galaxies in A2218: Probing molecular gas in the LIRG regime at high redshift
K. K. Knudsen, R. Neri, J. -P. Kneib +1
Context: Submillimeter galaxies (SMGs) are distant, dusty galaxies undergoing star formation at prodigious rates. Recently there has been major progress in understanding the nature…
Worst-Case Optimal Adaptive Prefix Coding
Travis Gagie, Yakov Nekrich
A common complaint about adaptive prefix coding is that it is much slower than static prefix coding. Karpinski and Nekrich recently took an important step towards resolving this: t…
Quark mass dependence of the pion vector form factor
Feng-Kun Guo, Christoph Hanhart, Felipe J. Llanes-Estrada +1
We examine the quark mass dependence of the pion vector form factor, particularly the curvature (mean quartic radius). We focus our study on the consequences of assuming that the c…
Nucleosynthetic osmium isotope anomalies in acid leachates of the Murchison meteorite
L. Reisberg, N. Dauphas, A. Luguet +3
We present osmium isotopic results obtained by sequential leaching of the Murchison meteorite, which reveal the existence of very large internal anomalies of nucleosynthetic origin…
The ages of Galactic globular clusters in the context of self-enrichment
T. Decressin, H. Baumgardt, P. Kroupa +2
A significant fraction of stars in globular clusters (about 70%-85%) exhibit peculiar chemical patterns with strong abundance variations in light elements along with constant abund…
Subjet distributions in deep inelastic scattering at HERA
ZEUS Collaboration, S. Chekanov
Subjet distributions were measured in neutral current deep inelastic ep scattering with the ZEUS detector at HERA using an integrated luminosity of 81.7 pb-1. Jets were identified…
Predictions for the cusp in eta->3pi0 decay
C. -O. Gullström, A. Kupść, A. Rusetsky
A realistic estimate of the cusp effect in the eta->3pi0 decay is required for the forthcoming high precision experiments. The predictions for the size of this effect are given wit…
A Note on Normal Forms of Quantum States and Separability
Ming Li, Shao-Ming Fei, Zhi-Xi Wang
We study the normal form of multipartite density matrices. It is shown that the correlation matrix (CM) separability criterion can be improved from the normal form we obtained unde…
Fixing D7 Brane Positions by F-Theory Fluxes
Andreas P. Braun, Arthur Hebecker, Christoph Ludeling +1
To do realistic model building in type IIB supergravity, it is important to understand how to fix D7-brane positions by the choice of fluxes. More generally, F-theory model buildin…
A Factor 3/2 Approximation for Generalized Steiner Tree Problem with Distances One and Two
Piotr Berman, Marek Karpinski, Alex Zelikovsky
We design a 3/2 approximation algorithm for the Generalized Steiner Tree problem (GST) in metrics with distances 1 and 2. This is the first polynomial time approximation algorithm…
Large hierarchies from approximate R symmetries
Rolf Kappl, Hans Peter Nilles, Saul Ramos-Sanchez +3
We show that hierarchically small vacuum expectation values of the superpotential in supersymmetric theories can be a consequence of an approximate R symmetry. We briefly discuss t…
Sources of contamination to weak lensing tomography: redshift-dependent shear measurement bias
Elisabetta Semboloni, Ismael Tereno, Ludovic van Waerbeke +1
The current methods available to estimate gravitational shear from astronomical images of galaxies introduce systematic errors which can affect the accuracy of weak lensing cosmolo…
Structure of the SMC - Stellar component distribution from 2MASS data
I. Gonidakis, E. Livanou, E. Kontizas +5
The spatial distribution of the SMC stellar component is investigated from 2MASS data. The morphology of the different age populations is presented. The center of the distribution…
Group actions on geodesic Ptolemy spaces
Thomas Foertsch, Viktor Schroeder
In this paper we study geodesic Ptolemy metric spaces which allow proper and cocompact isometric actions of crystallographic or, more generally, virtual polycyclic groups. We s…
Measurement of charged current deep inelastic scattering cross sections with a longitudinally polarised electron beam at HERA
ZEUS Collaboration
Measurements of the cross sections for charged current deep inelastic scattering in e-p collisions with longitudinally polarised electron beams are presented. The measurements are…
Thermalization of coupled atom-light states in the presence of optical collisions
I. Yu. Chestnov, A. P. Alodjants, S. M. Arakelian +4
The interaction of a two-level atomic ensemble with a quantized single mode electromagnetic field in the presence of optical collisions (OC) is investigated both theoretically and…
The Fate of Unstable Gauge Flux Compactifications
C. P. Burgess, S. L. Parameswaran, I. Zavala
Fluxes are widely used to stabilise extra dimensions, but if they arise within a non-abelian gauge sector they are often unstable. We seek the fate of this instability, focussing o…
