The templated growth of a chiral transition metal chalcogenide
We demonstrate that an intrinsically chiral, high Miller index surface of an achiral metal can be used to template the enantioselective growth of chiral transition metal chalcogenide films. Specifically, Cu(643)R can be used as a template for the enantioselective growth of a chiral copper telluride alloy surface. Beyond a critical alloy thickness the chiral influence of the Cu(643)R surface diminishes and an achiral surface forms. Our work demonstrates a new method of producing chiral transition metal chalcogenide surfaces, with potential applications in the study of structurally chiral topological insulators
A complete solution to neutrino mixing
Deviations from expectations have been claimed for solar, atmospheric and
high energy prompt neutrinos from charm decay. This information, supplemented
only by the existing very good upper limits for oscillations of the
at accelerator energies, is used as input to a phenomenological three-flavour
analysis of neutrino mixing. The solution found is unique and completely
determines the mass eigenstates as well as the mixing matrix relating mass and
flavour eigenstates. Assuming the mass eigenstates to follow the hierarchy
, their values are found to be
eV, eV, eV. These masses are
in agreement with the leptonic quadratic hierarchy of the see-saw model and
large enough to render energy-independent any oscillation-induced phenomenon in
solar neutrino physics observable on Earth. This possibility is not excluded by
the present knowledge of solar neutrino physics. The mixing angles are
determined to be , ,
. Small values of are typical of any solution
in which lies in the cosmological interesting region. The solution
found is not in serious contradiction with any of the present limits to the
existence of neutrino oscillations. The most relevant implications in particle
physics, astrophysics and cosmology are discussed.Comment: 17 pages, 3 figures, to be published in Astroparticle Physic

Observation of the decay
Several 14 Ω-e+ pairs of which 11.4±3.8 are consistent with the decay Ωc0→ Ω-e+ve were reconstructed. The probability that a background fluctuation was observed is 7.6×10-5. The measured Β·σ is (42.2±14.1±5.7) fb
