Limits on dark matter WIMPs using upward-going muons in the MACRO detector

The MACRO Collaboration, M. Ambrosio et al

We perform an indirect search for Weakly Interacting Massive Particles (WIMPs) using the MACRO detector to look for neutrino-induced upward-going muons resulting from the annihilat…

A Measurement of the tau->electron Branching Ratio

The OPAL Collaboration, G. Abbiendi et al

The branching ratio for the decay tau->e nue nutau has been measured using Z0 decay data collected by the OPAL experiment at LEP. In total 33073 tau->e nue nutau candidates were id…

Probing the plateau-insulator quantum phase transition in the quantum Hall regime

R. T. F. van Schaijk, A. de Visser, S. Olsthoorn +2

We report quantum Hall experiments on the plateau-insulator transition in a low mobility In_{.53} Ga_{.47} As/InP heterostructure. The data for the longitudinal resistance ρ_{xx} f…

A See-saw model of sterile neutrino

Biswajoy Brahmachari

If the smallness of the mass of the sterile neutrino is to be explained by the see-saw mechanism, the off-diagonal entries of the mass matrix needs to be protected by some symmetry…

Pauli-Limited Superconductivity in Small Grains

M. C. Bonsager, A. H. MacDonald

We report on an exploration of the mean-field phase diagram for Pauli-limited superconductivity in small metallic grains. Emphasis is placed on the crossover from the ultra-small g…

Sudakov suppression in the soft heavy to light meson transition form factor

Adam P. Szczepaniak, Anatoly Radyushkin

We calculate hard gluon contribution to the decay vertex that determines the heavy-to-light meson transition form factor at large recoil. It is found that resulting Sudakov suppres…
