Transverse spin structure of the nucleon from lattice QCD simulations
M. Göckeler, Ph. Hägler, R. Horsley +7
We present the first calculation in lattice QCD of the lowest two moments of transverse spin densities of quarks in the nucleon. They encode correlations between quark spin and orb…
First results from 2+1-Flavor Domain Wall QCD: Mass Spectrum, Topology Change and Chiral Symmetry with
D. J. Antonio, T. Blum, K. C. Bowler +23
We present results for the static interquark potential, light meson and baryon masses, and light pseudoscalar meson decay constants obtained from simulations of domain wall QCD wit…
Cosmology with Weak Lensing Surveys
D. Munshi, P. Valageas, L. Van Waerbeke +1
Weak gravitational lensing is responsible for the shearing and magnification of the images of high-redshift sources due to the presence of intervening matter. The distortions are d…
The near-IR shape of the big blue bump emission from quasars: under the hot dust emission
Makoto Kishimoto, Robert Antonucci, Omer Blaes
One primary difficulty in understanding the nature of the putative accretion disk in the central engine of AGNs is that some of its key intrinsic spectral signatures are buried und…
ACS photometry of newly-discovered globular clusters in the outer halo of M31
A. D. Mackey, A. Huxor, A. M. N. Ferguson +6
We report the first results from deep ACS imaging of ten classical globular clusters in the far outer regions (15 < R_p < 100 kpc) of M31. Eight of the clusters, including two of t…
Depolarization regions of nonzero volume for anisotropic, cubically nonlinear, homogenized nanocomposites
Jiajia Cui, Tom G. Mackay
An implementation of the strong-permittivity-fluctuation theory (SPFT) is presented in order to estimate the constitutive parameters of a homogenized composite material (HCM) which…
