Dalitz analysis of B→Kπ+ψ′ decays and the Z(4430)

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

From a Dalitz plot analysis of B→Kπ+ψ′ decays, we find a signal for Z(4430)+→π+ψ′ with a mass M=(4443-12-13+15+19)MeV/ c2, width Γ=(107-43-56+86+74)MeV, product branching fraction B(B̄0→K-Z(4430)+)×B(Z(4430)+→π+ψ′)=(3.2-0.9-1. 6+1.8+5.3)×10-5, and signific ...

Search for lepton-flavor-violating τ decay into a lepton and an f0 (980) meson

Olivier Schneider, Aurelio Bay, Chao Wang, Tagir Aushev, Remi Léandre Albert Louvot, Xiao Wang, Jing Li

We search for lepton-flavor-violating τ decays into a lepton (electron or muon) and an f0 (980) meson using 671 fb-1 of data collected with the Belle detector at the KEKB asymmetric-energy e+ e- collider. No events are observed and we set the following 90% ...

Spectral element approximation of the incompressible Navier-Stokes equations in a moving domain and applications

Gonçalo Pena

In this thesis we address the numerical approximation of the incompressible Navier-Stokes equations evolving in a moving domain with the spectral element method and high order time integrators. First, we present the spectral element method and the basic to ...

Degree and valuation of the Schur elements of cyclotomic Hecke algebras

Following the generalization of the notion of families of characters, defined by Lusztig for Weyl groups, to the case of complex reflection groups, thanks to the definition given by Rouquier, we show that the degree and the valuation of the Schur elements ...

Le carré de la fonction des diviseurs

Nicolas Bersier

Let d(n) denote Dirichlet's divisor function for positive integer numbers. This work is primarily concerned with the study of We are interested, in the error term where Ρ3 is a polynomial of degree 3 ; more precisely xΡ3(log x) is the residue of in s = 1. ...

Symmetry breaking in mechanical systems

The first part of this thesis studies the problem of symmetry breaking in the context of simple mechanical systems with compact symmetry Lie group G. In this part we shall assume that the principal stratum of the G-action on the configuration space Q of a ...

Generalizing the Affine Framework to HJM and Random Field Models

Pierre Collin Dufresne

We identify a class of term structure models possessing a generalized affine-structure that significantly extends the class studied by Duffie, Pan, and Singleton (2000) and Chacko and Das (2002). This class of models, which includes both infinite-state-var ...

On the products obtained from reaction of rac-diphenyl[2.2]para-cyclophanylphosphine with (cycloocta-1,5-diene)palladium(II)chloride

Paul Joseph Dyson

The reaction of Pd(cod)Cl-2 (cod = cycloocta-1,5-diene) with 1 and 2 equiv. of rac-diphenyl[2.2]paracyclophanylphosphine, rac-PPh2(C16H15), affords the dimer Pd{PPh2(C16H15)}Cl-2 (1) and the square-planar complex trans-Pd{PPh2(C16H15)}(2)Cl-2 (2), res ...

Generalized Bessel Functions in Incommensurate Structure Analysis

Gervais Chapuis

The analysis of incommensurate structures is computationally more difficult than that of normal ones. This is mainly a result of the structure-factor expression, which involves numerical integrations or infinite series of Bessel functions. Both approaches ...

Biocatalysts having an enzymic activity, and products obtained

Albert Renken

An enzyme carrier is prepd. by coating 0.1-0.25 mm mineral particles with chitosan [9012-76-4] and binding it with glutaraldehyde [111-30-8], which may be reduced by NaBH4. Alternatively, an enzyme may be bonded to the chitosan layer by a carbodiimide to s ...
