We search for a charged partner of the X(3872) in the decay B --> X- K, X- --> J/psi pi- pi0, using 234 million BBbar events collected at the Y(4S) resonance with the BaBar detecto…
Polarized Electrons for Linear Colliders
J. E. Clendenin, A. Brachmann, E. L. Garwin +7
Future electron-positron linear colliders require a highly polarized electron beam with a pulse structure that depends primarily on whether the acceleration utilizes warm or superc…
Highly Ionized Gas in the Galactic Halo and the High Velocity Clouds Toward PG 1116+215
Rajib Ganguly, Kenneth R. Sembach, Todd M. Tripp +1
We have obtained high resolution FUSE and HST/STIS echelle observations of the quasar PG 1116+215. The semi-continuous coverage of the ultraviolet spectrum over the wavelength rang…
A systematic study of polarized electron emission from strained GaAs/GaAsP superlattice photocathodes
T. Maruyama, D. -A. Luh, A. Brachmann +8
Spin-polarized electron photoemission has been studied for GaAs/GaAsP strained superlattice cathodes grown by gas-source molecular beam epitaxy. The superlattice struct…
Atomic Hydrogen Cleaning of Polarized GaAs Photocathodes
T. Maruyama, D. -A. Luh, A. Brachmann +6
Atomic hydrogen cleaning followed by heat cleaning at 450C was used to prepare negative-electron-affinity GaAs photocathodes. When hydrogen ions were eliminated, quantum ef…
Characterizing Subgroups of Compact Abelian Groups
Dikran Dikranjan, Kenneth Kunen
We prove that every countable subgroup of a compact metrizable abelian group has a characterizing set. As an application, we answer several questions on maximally almost periodic (…
Spectroscopy of Red Giants in the LMC Bar: Abundances, Kinematics, and the Age-Metallicity Relation
Andrew A. Cole, E. Tolstoy, J. S. Gallagher +1
We report metallicities and radial velocities derived from spectra at the near-infrared calcium triplet for 373 red giants in a 200 square arcminute area at the optical center of t…

From parameter space constraints to the precision determination of the leptonic Dirac CP phase
Patrick Huber, Manfred Lindner, Walter Winter
We discuss the precision determination of the leptonic Dirac CP phase in neutrino oscillation experiments, where we apply the concept of ``CP coverage''. We demonstrate th…

The AMANDA Collaboration, M. Ackermann
The results of a search for point sources of high energy neutrinos in the northern hemisphere using data collected by AMANDA-II in the years 2000, 2001 and 2002 are presented. In p…
Surface diffuseness anomaly in heavy-ion potentials for large-angle quasielastic scattering
