Observation of the Radiative Decays of Upsilon(1S) to chi(c1)

Olivier Schneider, Yiming Li, Mingkui Wang, Chao Wang, Tagir Aushev, Sun Hee Kim, Donghyun Kim, Xiao Wang

We report the first observation of the radiative decay of the Upsilon(1S) into a charmonium state. The significance of the observed signal of Upsilon(1S) -> gamma chi(c1) is 6.3 standard deviations including systematics. The branching fraction is calculate ...

Search for a Light CP-odd Higgs Boson and Low-Mass Dark Matter at the Belle Experiment

Olivier Schneider, Yiming Li, Chao Wang, Tagir Aushev, Sun Hee Kim, Tara Nanut, Jun Yong Kim, Ke Huang, Ji Hyun Kim, Donghyun Kim, Lei Li

We report on the first Belle search for a light CP-odd Higgs boson, A(0), that decays into low mass dark matter, chi, in final states with a single photon and missing energy. We search for events produced via the dipion transition (sic)(2S) -> (sic)(1S)pi( ...

Observation of e(+) e(-) -> gamma chi(c1) and search for e(+) e(-) -> gamma chi(c0), gamma chi(c2), and gamma eta(c) at root s near 10.6 GeV at Belle

Olivier Schneider, Yiming Li, Mingkui Wang, Chao Wang, Tagir Aushev, Sun Hee Kim, Jun Yong Kim, Ji Hyun Kim, Donghyun Kim, Xiao Wang, Lei Li

Using data samples of 89.5 fb(-1), 711.0 fb(-1), and 121.4 fb(-1) collected with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider at center-of-mass energies 10.52, 10.58, and 10.867 GeV, respectively, we study the exclusive reactions e(+) ...

Spherical Deconvolution of Multichannel Diffusion MRI Data with Non-Gaussian Noise Models and Spatial Regularization

Jean-Philippe Thiran, Erick Jorge Canales Rodriguez, Alessandro Daducci, Lester Melie Garcia

Spherical deconvolution (SD) methods are widely used to estimate the intra-voxel white-matter fiber orientations from diffusion MRI data. However, while some of these methods assume a zero-mean Gaussian distribution for the underlying noise, its real distr ...

Measurement of e(+)e(-) -> gamma chi(cJ) via initial state radiation at Belle

Olivier Schneider, Tagir Aushev, Sun Hee Kim, Jun Yong Kim, Ji Hyun Kim, Donghyun Kim, Dipanwita Dutta, Xiao Wang

The process e(+)e(-) -> gamma chi(cJ) (J = 1, 2) is studied via initial state radiation using 980 fb(-1) of data at and around the Gamma(nS) (n = 1, 2, 3, 4, 5) resonances collected with the Belle detector at the KEKB asymmetricenergy e(+)e(-) collider. No ...

Experimental response of Salix cuttings to different flow regimes due to human activities

Alexandre Buttler, Paolo Perona, Pascal Turberg, Constant Signarbieux, Lorenzo Gorla

Hydropower production and other human activities change the natural flow regime of rivers, in turn impacting the riparian environment. The main challenge in order to define eco-sustainable flows is to quantify the effects in terms of geomorphology and ecos ...

A weighted empirical interpolation method: a priori convergence analysis and applications

Alfio Quarteroni, Gianluigi Rozza, Peng Chen

We extend the classical empirical interpolation method to a weighted empirical interpolation method in order to approximate nonlinear parametric functions with weighted parameters, e.g. random variables obeying various probability distributions. A priori c ...

Experimental response of Salix cuttings to sudden water table changing dynamics

Alexandre Buttler, Paolo Perona, Pascal Turberg, Constant Signarbieux, Lorenzo Gorla

Hydropower production, agriculture and other human activities change the natural flow regime of rivers, in turn impacting the riparian environment. Inadequate flow rules (e.g., minimal or residual flows) reflecting our limited understanding of eco-hydrolog ...

Search for charmonium and charmoniumlike states in gamma(2S) radiative decays

Olivier Schneider, Yiming Li, Mingkui Wang, Chao Wang, Tagir Aushev, Jun Yong Kim, Remi Léandre Albert Louvot, Ji Hyun Kim, Xiao Wang, Jing Li, Xuan Li

Using a sample of 158 x 10(6) gamma (2S) events collected with the Belle detector, charmonium and charmoniumlike states with even charge parity are searched for in gamma (2S) radiative decays. No significant chi(cJ) or eta(c) signal is observed, and the fo ...
