A lattice estimate of the g_{D^* D pi} coupling [PDF]

, 2002
We present the results of the first direct determination of the g_{D^* D pi} coupling using lattice QCD. From our simulations in the quenched approximation, we obtain g_{D^* D pi} = 18.8 +/- 2.3^{+1.1}_{-2.0} and hat(g) = 0.67 +/- 0.08^{+0.04}_{-0.06 ...

Green Scalar Function Method for Analyzing Dielectric Media

Applied Sciences
In this work we present a formalism based on scalar Green’s functions to deal with electromagnetic scattering problems. Although the formulations of the Mie theory and Born approximations in terms of electromagnetic scattering are well known and relevant,

Scattering of light halo nuclei on heavy target at energies around the Coulomb barrier

EPJ Web of Conferences, 2014
We report here on experiments performed at TRIUMF to study the scattering of the light halo nuclei 11Li on lead at energies below and around the Coulomb barrier.

Correlation energy contribution to nuclear masses

, 2004
The ground state correlation energies associated with collective surface and pairing vibrations are calculated for Pb- and Ca-isotopes. It is shown that this contribution, when added to those predicted by one of the most accurate modern nuclear mass ...

Top Quark Flavor Changing Couplings at a Muon Collider

Advances in High Energy Physics
There is growing interest in the development of a muon collider that would make it possible to produce lepton collisions at energies of several TeV. Among others, there can be significant contributions to electroweak gauge boson, Higgs boson, and top ...

Self-assembly of active amphiphilic Janus particles

New Journal of Physics, 2017
In this article, we study the phenomenology of a two dimensional dilute suspension of active amphiphilic Janus particles. We analyze how the morphology of the aggregates emerging from their self-assembly depends on the strength and the direction of the ...

Electrochemical Analysis on Compounds of the Vitamin B6 Family Using Glassy Carbon Electrodes

International Journal of Electrochemical Science, 2012
The electrochemical reduction of vitamin B6 group and related compounds has been performed at pH neutral using glassy carbon electrodes. Irreversible bi- or tetra-electronic processes controlled by diffusion on the top of the wave are observed for these ...

Spin-torque driven magnetic vortex self-oscillations in perpendicular magnetic fields

, 2010
We have employed complete micromagnetic simulations to analyze dc current driven self-oscillations of a vortex core in a spin-valve nanopillar in a perpendicular field by including the coupled effect of the spin-torque and the magnetostatic field ...

Elucidating the Role of Surface Ligands on the Oxidative Etching of Au Bipyramids During Photothermia Using Liquid Cell Transmission Electron Microscopy

Advanced Functional Materials, EarlyView.
Gold bipyramids can act as efficient plasmonic nanoheaters, but they often reshape during laser heating. This study shows that oxygen nanobubbles drive oxidative etching and that surface ligands control stability. CTAB‐ and citrate‐coated particles blunt and lose optical performance, whereas polystyrene sulfonate preserves shape and heating by ...
