Size Distribution of Superparamagnetic Particles Determined by Magnetic Sedimentation
J. -F. Berret, O. Sandre, A. Mauger
We report on the use of magnetic sedimentation as a means to determine the size distribution of dispersed magnetic particles. The particles investigated here are i) single anionic…
zCOSMOS: A Large VLT/VIMOS redshift survey covering 0 < z < 3 in the COSMOS field
S. J. Lilly, O. Le Fevre, A. Renzini +42
zCOSMOS is a large redshift survey that is being undertaken in the COSMOS field using 600 hours of observation with the VIMOS spectrograph on the 8-m VLT. The survey is designed to…
Quantum corrections to the effective neutrino mass operator in 5D MSSM
Aldo Deandrea, Pierre Hosteins, Micaela Oertel +1
We discuss in detail a five-dimensional Minimal Supersymmetric Standard Model compactified on extended by the effective Majorana neutrino mass operator. We study the evol…
Mass modelling of dwarf spheroidal galaxies: the effect of unbound stars from tidal tails and the Milky Way
Jaroslaw Klimentowski, Ewa L. Lokas, Stelios Kazantzidis +3
We study the origin and properties of the population of unbound stars in the kinematic samples of dwarf spheroidal galaxies. For this purpose we have run a high resolution N-body s…
Scalar meson properties from D-meson decays
B. El-Bennich, O. M. A. Leitner, B. Loiseau +1
Decay amplitudes of D(D_s)->f0(980)X, X=pi, K, are compared to experimental branching ratios with the aim of singling out the poorly known D->f0(980) transition form factor in thes…
Can we probe right-handed charged quark currents?
Micaela Oertel
Different scenarios of new physics beyond the standard model give rise to a direct coupling of right-handed quarks to W bosons. We will discuss how the prediction of the Callan-Tre…
