Measurement of the branching fractions for B0→Ds+π - and B0→Ds-K+ decays

Olivier Schneider, Aurelio Bay, Remi Léandre Albert Louvot, Mingkui Wang, Chao Wang, Tagir Aushev, Vladislav Balagura, Sun Hee Kim, Ji Hyun Kim, Xiao Wang, Jing Li

We present a study of B0→Ds*+π- and B0→Ds*-K+ decays based on a sample of 657×106 BB̄ events collected with the Belle detector at the KEKB asymmetric-energy e+e- collider. We measure the branching fractions to be B(B0→Ds*+π-)=(1.75±0.34(stat)±0.17(syst) ±0 ...

Geodesic flows on semidirect-product Lie groups: geometry of singular measure-valued solutions

Cesare Tronci

The EPDiff equation (or dispersionless Camassa-Holm equation in 1D) is a well known example of geodesic motion on the Diff group of smooth invertible maps (diffeomorphisms). Its recent two-component extension governs geodesic motion on the semidirect produ ...

On the estimation of geodesic paths on sampled manifolds under random projections

Pierre Vandergheynst, Matteo Sorci

In this paper, we focus on the use of random projections as a dimensionality reduction tool for sampled manifolds in high-dimensional Euclidean spaces. We show that geodesic paths approximations from nearest neighbors Euclidean distances are well-preserved ...

Multiplicities of simple closed geodesics and hypersurfaces in Teichmuller space

Hugo Parlier

Using geodesic length functions, we define a natural family of real codimension 1 subvarieties of Teichmuller space, namely the subsets where the lengths of two distinct simple closed geodesics are of equal length. We investigate the point set topology of ...

Percolative properties of hard oblate ellipsoids of revolution with a soft shell

Peter Ryser, Claudio Grimaldi, Niklaus Johner, Gianluca Ambrosetti

We present an in-depth analysis of the geometrical percolation behavior in the continuum of random assemblies of hard oblate ellipsoids of revolution. Simulations were carried out by considering a broad range of aspect-ratios, from spheres up to aspect-rat ...
